A personal computer is a general-purpose computer whose size, capabilities and price make it useful for individuals, and is intended to be operated directly by an end-user with no intervening computer time-sharing models that allowed systems to be used by many people, usually at the same time. Personal computers may be connected to a local area network (LAN), either by a cable or a wireless connection, and through that to the Internet. A personal computer may be a laptop computer or a desktop computer running an operating system such as Windows, Linux or Macintosh OS.

No single Antivirus application (despite claims by manufacturers) will catch or protect you from all Virus / Malware or Spyware threats. That doesn't stop you from further protecting yourself however - and this article is to show you how.

Andy,

I'm impressed with this article.  I like the way you tested it out. Extremely well thought out.  Some things you may woah to address:

1. Don't repeat the summary.  Summary was good, but repeating it (or copying the first paragraph) is not a great practice.
2. Remove the word "not" from the summary.

I had a somewhat similar situation. I built my computer, ordered parts off Newegg. Included was a nice graphics card, my first one. I kept fiddling with the monitor wondering why it wasn't displaying. After awhile, I realized the monitor was hooked to the mother board, instead it needed to be hooked to the new graphics card. lesson learned.

I don't know if many of you have made the great mistake of using the Cisco Thin Client model with the management software VXC. If you have then you are probably more then familiar with the incredibly clunky interface, the numerous work arounds, and the awful customer support. I can not tell you the countless hours i have spent on the phone with Cisco attempting to fix issues.

Well I have good and bad news for you all. Cisco has "End of Lifed" this platform and will no longer continue to support or sell it. The official timeline for this is below. But for some of you who have invested a lot of time and more importantly money into the product are probably pretty upset.

http://www.cisco.com/c/en/us/products/collateral/collaboration-endpoints/virtualization-experience-client-manager/eos-eol-notice-c51-731181.html

Well, there is a solution out there: the Dell Wyse Platform. The VXC platform was "purchased" from Wyse and simply branded by Cisco and they made a few coding changes but all in all the source code is the same. Even the asthetic look of the software is almost identical to the VXC. However, Wyse takes much better care of the software and has had out for quite some time a version of the management software that is compatible with Windows Server 2012 R2, that is something those of us with Cisco have been waiting for, for a while.

Wyse also releases patches much more quickly and has much better support, as well as an FAQ with discussion boards and forums. And the…

We are looking at Wyse with Cloud Client Manager. Are you aware if it's able to manage both WyseOS and Windows Embedded TCs? We're also looking at the desktop extender LinuxOS to load on old laptops to keep them from going obsolete. Working with a rep there but haven't gotten answers yet.

Upper back Pain:
My back hurt for months. Upper back, mostly my neck, spine and across my shoulder blades. I was getting headaches too, that felt like they were caused by tension in my shoulders, but now I feel fine! I'm sharing this hoping someone else can benefit.

Diagnosis:
I felt like I was stooping while I sat at my desk at work, the monitors were a bit low with no height adjustment so I was bending forward to look at them which made the pain in my back feel worse.

Health and safety studies suggest that the height of your chair seat is adjusted so when sitting with your feet flat on the floor and your lower legs vertical, your knees bend at roughly 90 degrees so your thighs are horizontal or sloping slightly downward, your back should be vertical and supported by the back of the chair, and the arms of the chair should be raised to the height of your elbows so as to just support your forearms, basically sit up straight.

The page at: http://www.globaltotaloffice.com/ggi_08/adjusting_a_chair.html gives a pretty good description of how to adjust an office chair for comfort, right up until step eleven where you forget all the settings you have made and change it all so it will fit underneath the desk.

All the other desk related instructions are about raising the chair or using a footrest if your feet don't reach the floor. None of them suggest what to do if you are too tall …

I have been focused recently on finding the source(s) of my neck and back pain. A couple of weeks ago I dragged a lectern from the conference room into my office and use it periodically during the day as a standing desk. It helps relieve the neck and back pain, however, my feet and legs start to hurt if I use it too much : (

Another example: I have an unusual tall man's build in that my legs are disproportionately longer than my torso. My commuter car was causing me serious leg pain until I modified the driver's seat rails so I could move the chair three more inches further back than what the manufacturer intended. The pain relief was amazing. Now if I could just extend the steering column so I can comfortably reach the wheel : (

I'm going to modify my office desk ergonomics as a result of this article. My chair does not fit under my desk currently, but it will soon. With my long legs, I might need 6" blocks!!

Thanks for the tips!

This is an excellent article and clearly demonstrates the benefits of having a comfortable seating and monitor position for people who have to sit at a desk for many hours in a row.  Another difficulty arises where the desk is a shared one and the other user, or main user, user is diminutive in stature.

I have to sit at a desk for about 3 or 4 hours to do nightly reports after the work is finished in the warehouse and other areas.  I use the dayshift Manager's desk, and he is fairly small.  I used to be 6' 5" tall but I think I have shrunk to just over 6' 3" over the years.  With the chair raised to a maximum height the arms don't fit under te desk and, to make matters worse, the monitor has never been upgraded from a 15 inch one that the Manager never cleans.  I now have to wear reading glasses and I am convinced that straining to see the screen has accelerated the natural degradation of my eyesight and I often suffer neck and shoulder pain from the seating position if I have had to sit at the desk too long.

I purposefully take very frequent breaks, probably for about 5 or 10 minutes every 20 minutes, during which I walk around and loosen up my neck, shoulders, back, and legs.  I am fortunate that I am able to get away from the desk and that I am not stuck there all night, and I must look rather silly each time I stand up and do a freeform dance along the corridor.  If I was forced to sit there all night I would have insisted on a larger screen and a higher desk, although it would be up to me to reduce my middle-aged paunch so I could pull the chair closer to the desk.

Computer running slow? Taking forever to open a folder, documents, or any programs that you didn't have an issue with before? Here are a few steps to help speed it up.

The programs mentioned below ALL have free versions, you can buy them if you want, but I suggest using the free version in this case.
 
Antivirus

First step is to check, and clean up, any viruses / malware you might have installed on your computer. Any good antivirus will help with this. There are many out there, if you don’t have any currently installed, you should do this right away. Many of the big names have free 30 day trials to find one you like. There are also many free ones, but they may only give you a quarter of the feature or not have real-time scanning as an option. The only downside is this could slightly slow your computer as it will be running in the background at all times. However, it is very important you have an antivirus program installed to help prevent you from becoming infecting and losing personal information.

Once installed run a full system scan and clean up any viruses it may find.

One suggested antivirus program to run is MalwareBytes found at (www.malwarebytes.org). Use the free version (this does not do real time scans unless you buy it. However it is free to do on demand scans for this case. However, I highly recommend buying a antivirus program from your favorite antivirus vendor (or do some research and pick which one is best for you).

Also - ninite.com is a fabulous resource for installing the latest version of utilities and other software we've come to depend on (Adobe Reader, Flash, Java, Malwarebytes, etc.) cleanly and quickly. It installs the software for me and doesn't allow any of the extra junk (like toolbars) to get installed or enabled.

There are other things that, I feel, should be mentioned here.

When removing unwanted or unused programs from your computer, the standard windows uninstaller frequently leaves files and registry entries that should have been removed.  This is also true for some 3rd party uninstallers.  One program that consistently removes everything, and gives you an option for uninstalling in safe, medium and advanced modes is the Revo uninstaller.  It will present a list(s) of left-over items and allow you to select the ones you want to remove.  Even Microsoft Help Desk personnel use this program when remotely working on someones pc.  It begins by using the standard uninstaller (either the software's own or windows) then collects left-over information and presents it to you.  Very user-friendly.  Left-over registry entries are included in items presented to remove.

You can go to the start menu and click or type run and a window will open.  Type in %temp% and click <ok>.  A window will be opened that presents a list of files.  Select all of them and delete them.  Some may be open and so just skip their deletion.

Go to your C:\ drive icon in My Computer or the file explorer and right click on it and run Disk Clean up.  Here, you can clean up system files as well, such as, windows log files, left-over windows update files, and others.

Additionally, just running the defragmentation program does not ensure that all files have been defragmented.  Go to the start menu or search programs and enter cmd and select the program.  A Command prompt window will appear that you may be familiar with if you have ever used the old DOS prompt, which is basically what this is.  Type in defrag ? and <ENTER>.  A list of defrag options will be presented that you can specify when you run the defrag command from this window.  Specify the ones you want and run the program.  NOTE: you may need to run this with administrator privileges.  Do this by right clicking the cmd prompt program and then click run as administrator.

Always remember, your computer may never become faster than it was when you first purchased it and opened the box.  If it was slow to start with, barring pre-installed software, it will usually be this slow to end with and you may need to just go ahead and purchase one with a faster processor etc.  One item that may make a difference here is more RAM.

The following comes from Wikipedia.
 "A myth has arisen that RDC significantly slows local file transfers and should be switched off; a Microsoft TechNet Web page by a Microsoft Directory Services Team member comprehensibly debunks this with detailed timings, additional to the fact that a service which is not invoked by software cannot have any effect, detrimental or otherwise"
 I did not find the TechNet page but would like to see Microsoft's comments on RDC.

I have found the most common causes of slow computers are
1- malware
2 - slow hard disks especially 2.5" drives. They do not report as faulty but the tests take an exceptionally long time to complete. We use Spinrite to test them
3 - as mentioned earlier, all the crap software the manufacturer has auto starting on boot. Ccleaner is great for disabling them.
4 - also mentioned earlier - not enough RAM

Power Supply - no lights or fans running

If you have no lights or fans running then either you power is bad, turned off (check switch) or the power supply needs to be replaced. That's a relatively easy fix. 

Power-Supply.jpg
Other Possibilities

If the power supply is not your problem then you may want to reconsider repairing your PC. Some items are easier to repair than others. Depending on the age of the PC it may be wiser to put money towards a new PC rather than invest in the old one.

Memory

If you are OK with replacing a power supply you might consider replacing the memory. Typically a PC will give you an audio alarm or a visual indication of bad memory so it's not the same symptoms as the power supply.

CPU

CPU is also fairly easy to replace but you will need to identify the CPU for your system board. If you have a similar PC you might try swapping a known good CPU into the problem PC. There are lots of places selling used CPUs for bargain prices so it might be worthwhile to order one. Many will let you return the CPU as long as you don't damage it.

You should probably invest in some thermal paste if you are going to replace the CPU.

System Board

System boards can be replaced but it probably isn't worth the effort on an older computer. It can be a nightmare just matching up system board to your model and the cost can be substantial. My …

This article is a cursory discussion of Intel SpeedStep Technology (SpeedStep) and Enhanced Intel SpeedStep Technology (EIST).  The goal is more to illuminate what these technologies are and are not.  The detail of how each technology works is not addressed here.  Intel SpeedStep exists in several versions, dating back to the Pentium III processor.  Intel's most current implementation, EIST (Enhanced Intel SpeedStep Technology), includes realtime Level 2 cache capacity variation.

It is worthy to note that AMD provides a similar group of technologies known as PowerNow!, Cool'n'Quiet, and Optimized Power Management (an adaptation of PowerNow! for newer Opterons).  

Regardless of the processor type or class, and without regard to any particular generation, each of these technologies perform the same basic task - temporarily alter the operating frequency and power consumption of the processor(s) according to demand.  Oversimplified, this is accomplished by altering the base frequency of the CPU, core voltage, or a combination of both. Low demand means less power needed, and obviously, high demand means more power.

Wiki arguably has the most concise definition (see link below) :
SpeedStep is a trademark for a series of dynamic frequency scaling technologies built into some Intel microprocessors that allow the clock speed of the processor to be dynamically changed by software. This allows the processor to meet the instantaneous performance needs of the operation

This is an article based on some fact, and much personal opinion. While you may differ from me in the things you value in a personal computer, I hope this advice can serve to inspire a more objective comparison of two computers, help your figure out whether the price of a computer you're looking at is justified, and help you realize when someone is pulling the wool over your eyes.

What to look for in a new computer

If you're buying a new computer, you probably want something that's fast, uncluttered, and maybe something that's nice to look at too. When comparing computers, manufacturers throw a lot of statistics and features at you that may look like a great package, but if you want to pull off a good deal, you need to make sure you can focus on the important things and ignore all the promotional garbage and filler they use to try and distract from other possible shortcomings.

Focus on the Features that Count

Processor Clock Speed, and Processor Cache
Better memory improves multi-tasking and performance. Clock Speed is expressed as a frequency, such as 2.40 GHz. Processor Cache is in the neighbourhood of 4MB of 6MB for a powerful beast. Good desktops can hit 2.93 GHz, probably better before long. You can compare a vast number of CPUs here. Keep in mind that some of these are made for servers, and aren't something you would get in a desktop.
