Hi Experts,
My PCs performance is super slow.  It seems to be worsening by the minute.
Sometimes when I have an application open,  my PC will just freeze in the middle of what I am doing.
What can I do to improve my PC's performance?

thank you,
mrotor

Possibly a dying hard disk drive. Download HardDiskSentinel. It will report on the status of your HDD.
Could also be computer overheating - more likely if it is a laptop.
Could be faulty RAM.
Could be a virus - download MalwareBytes to check.
More RAM may help.
A solid state disk may also help.

First of all open the performance monitor (open Task Manager - Performance - Performance Monitor).
See there which part of the hardware is mostly used. HDD or CPU or RAM.
Then tell us what drive, CPU and RAM amount you have.
Run also Windows Experience Index check. It shows where the weakest part of your hardware is.

If the hard drive is fine (after you test it), and the computer is slowing by the minute, then you have viruses and/or malware.

Scan with your own anti virus tool and then with Malwarebytes.

Let us know the results.

Use the disk manufacturer's diagnostic tool to test it, and not any other 3rd party tool. Only the manufacturer's diagnostics are reliable.

i would start with basics : is this a PC or laptop ? and clean all fans and vents  from dust
then - if no sign of malware - i run a ram and disk diagnostic, to be sure of the basics
i use the ubcd for this :
Hardware diagnostic CD    UBCD

go to the download page, scroll down to the mirror section, and  click on a mirror to start the download
Download the UBCD and make the cd   <<==on a WORKING PC, and boot the problem PC from it
Here 2 links, one to the general site, and a direct link to the download

since the downloaded file is an ISO file, eg ubcd527.iso - so you need to use an ISO burning tool
if you don't have that software, install cdburnerXP : http://cdburnerxp.se/

If you want also the Ram tested - run memtest86+ at least 1 full pass,  - you should have NO errors!
 
For disk Diagnostics run the disk diag for your disk brand (eg seagate diag for seagate drive)  from the HDD section -  long or advanced diag !  (runs at least for30 minutes)

http://www.ultimatebootcd.com/download.html             download page

**  you can make a bootable cd - or bootable usb stick

for completeness -here's how i handle disk problems : http://www.experts-exchange.com/Storage/Hard_Drives/A_3000-The-bad-hard-disk-problem.html
mainrotor,

Your PC/laptop could be 'super slow' for any number of reasons.  Without further information on the general condition of your system, it's impossible to say.
However it could be:
1) Too many programs running on startup, taking up too much memory
2) Virus/Malware issues
3) Storage drive (hd drive), too fragmented.... might be an idea to check with Defrag (Disk Defragmenter)
4) Hardware issue (overheating perhaps) - caused by something else

These are just some things to consider.
