Running Windows 7 Professional SP-1 32-bit, the system has started to freeze, randomly, since yesterday.  No new hardware or software has been installed.  Freezing happens randomly, not consistently with any application or activity, and requires rebooting.  Checkdsk found no problems on the system drive.  All the components are new: Asus P8H67-M PRO/CSM (REV 3.0) (Socket 1155) with the latest bios, Intel Core i5-2500K Sandy Bridge 3.3GHz  6MB Cache, LGA 1155, (4) Corsair Vengeance 4GB 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800); (2) IDE HDD:  WD 3200JB  320 GB (Master) + WD5000AAKB 500 GB (Slave); SATA HDD:   WD30EZRX  3TB;  SATA REV 35GB USB Drive.  Using the Western Digital diagnostic tool, all hard drives passed a quick test.  Using Intel's CPU testing utility, the CPU passed all tests.  Restoring the system drive with an image saved from before this issue, the issue persisted.

I suspect a hardware problem, but I'd appreciate some guidance about how to troubleshoot this systematically.

Thank you.

I often receive the below error message when attempting to open Word files.  At the time of the latest occurrence, 67% of 8GB of RAM was in use.  Rebooting the Laptop usually corrects the issue.  I can open a new blank Word file even after the error is received when trying to open an existing Word file.  

Does anyone have any thoughts as to why this is happening?  

I am working on a Lenovo Laptop that has the attached system profile.  The laptop has not been performing as I expected for a quite a while, but I don't know enough to  isolate any issues that are occurring with the software or hardware.

Word experienced an error trying to open the file.
Try these suggestions.
* Check the file permissions for the document or drive.
* Make sure there is sufficient free memory and disk space.
* Open the file with the Text Recovery converter

Can I use CREATIVE BLUETOOTH speakers to help adit Mac.Audacity audio files?

My MacBook has little speakers and I need a louder set. Can I use CREATIVE BLUETOOTH speakers as output for my Audacity?

I connected the speakers to my Mac via BT but when I open Audacity, I do not see CREATIVE as an option on the speaker drop down.

Is this a connect that should work?

I had this question after viewing Citrix profile management issue.


i still need more info to under stand

1- Exclusion List - directories and files  in Citrix profile management

if i decied to exclude this list that mean this folders will be saved on the xenapp server local disk

and my xenapp server  disk less because it boot over network from PVS server  so the all Vdisk actual will use Xenapp memory

my question if i want to configure Exclusion List - directories and files so maybe i have to create for every work a local disk to use as a store for all of these excluded directories

so how can i tell this inside citrix UPM policy on Citrix director  

i really don't want the excluded directories to be loaded on drive C where it is coming over network from PVS server  

anybody here can tell me how this work why Citrix recommended this (( we have 10 G Ethernet so keep  the whol profile on the network share should make scene ))

the same question for  

Directories and files to synchronize

to synchronize to where ?

the same question for

Folders to mirror       mirror to where

sorry if anyone has any link will show the configuration for such configuration step by step or good links to explain this to me

i am using only citrix UPM on a shared file system and i know nothing about configuring

Exclusion List - directories      and files

Directories and files to synchronize

Folders to mirror  

thanks in advance
Using two microphones with Audacity (Mac High Sierra)

I have two microphones working as inputs with Audacity, via this box:


But, Audacity creates a single track with Left and Right sub-channels for a single channel, while I need each to have each microphone in its own channel.

Or, is there a way to convert a track with Left and Right to two distinct channels?

thinking to sell used laptop

Any good sites that give good price on them

Please advise

Brand new HP ProLiant ML350 Gen10 with 8 x 16 GB original HP RAM gives memory configuration error. OS is 2016 Server std. The server has one CPU and 12 memory slots pr. CPU. As per HPE documentation slots 3 to 6 and 7 to 10 shall be populated when using 8 RAM chips. This looks a bit weird to me as I am used to first populate all the white slots first. But this setup is documented both inside the server cover and on HPE website. I have upgraded to latest SPP (11-2018). Can anyone confirm that this is indeed the correct way to do this?

Alternatively, when I only use 6 x 16 GB RAM in all the white slots everything is OK. But in this scenario I cannot figure out where to put the last to chips. I always get a message that memory is unbalanced (error 510).

Has anyone attempted to connect laptop with broken screen to another working screen but from another laptop make/model?  
 I'd assume it should have different voltage, drivers, etc. Besides mechanical issues, like hinges, etc.

Anyone done that?

what should be the properties to look for?

as i understand, some have allso the option to renew a battery, from (near) dead; that of course costs more
and how much current does it use, say per hour or per day?

I have a Switched Rack AP8941 24-Outlets Pdu and I am trying to find the manual. There was a short circuit and half of the rack of this 24 outlets went down. The breaker on the top went to a off position. I guess this is a safety mechanism.  I am afraid by resetting the breaker, it will reset the whole 24-outlets rack. Any ideas how to do this safely? Thanks
Why when I increase the  base resistor  the VCE voltage drop dicreases?
I have 5 ESXI hosts. All EXI Hosts can see/have connections to 2 HP fibre Sans and a few ISCSI SANS.
Each ESXI has an add on HP 8GB FC to PCI Express HBA Card.

one of the ESXI host had the system board replaced. When ESXI came back up, it had no problems seeing the ISCSI SANS. But it was unable to see the 2 HP fibre SAN. Looking at the storage adapters, Vsphere client shows "VMHBA1 fibre Channel unknown" while "VMAHBA2 Fibre Channel online"

I have rescan for hardware changes. I see no options to re-attached/mount storage back. How do I get the VMHBA2 to reconnect to the HP SAN? All the other ESXI hosts can see it.

I have a MS Surface model 1796 and I'd like to purchase a keyboard. But I don't know what Surface Pro I have and what keyboard is compatible.
I have APC UPS 1500VA Smart-UPS that is connected to my PC using a APC UPS Communications Cable. I have installed the software and the server and agent services are running on my PC (see screenshot2.jpg). I have also installed PowerChute Business Edition software and I was able to login to my LAN, but it doesn't detect the UPS battery (see screenshot1.jpg).

I'm not sure if this is a cable issue or a driver issue.  I opened device manager to look at the connected devices and I don't see the APC UPS battery listed. I believe it should show up under Human Interface Devices or maybe Universal Serial Bus Controllers (see screenshot3.jpg). I also ran a USB app to check for missing drivers called USBDeview and it shows the USB UPS as not connected (see screenshot4.jpg).

Am I missing a driver or is the cable or ports bad?  If I'm missing drivers, which drivers do I need to install? If it is the cable, did I get the wrong cable or should I buy a new one? If it is the ports, then  what should I try as an alternative? I've been trying to troubleshoot the issue, but have been unsuccessful and not sure what to try next. There is limited information that I have found to help resolve the issue.

The goal is to get the agent running on my local PC that is connected to the APC UPS battery so I can monitor the battery usage and power.

Any help on how to troubleshoot or fix this issue  would be appreciated.

I have a circuit with a transistor and a light emmiting diode:

My source voltage is 11.6 volts

My transistor is in series with 2 resistors and the light emmiting diode.

The resistors values are 1000 Ohm each.

The base is connected to a 0.7 volt supply.

Voltage drop in resistors is 2.7 volts each.

The voltage drop in the light emmiting diode is 2.7 volts

Why is there a 3.4 V voltage drop between emmiter and collector?Shouldnt it be 0 and the voltage drop in the resistors be (11.6-2.7)/2 volts ?

What am i missing?
Hi. I am attempting to install 16.04 server on a hardware raid 1 array. I created a boot partition (1 mb - I also tried larger, but same error), main disk (3.8 TB) and a swap partition (.2 TB). I am able to install on this configuration, but when the system boots for the first time I receive the error:

"error attempt to read or write outside of disk 'hd0'"

Then, it dumps me to the grub rescue prompt. At this prompt, I have tried setting the root and path to the boot partition, but I am never able to ls see anything in that directory, nor can I get back to the grub menu.

I have read several others with the same problem, but have not been able to recover from this error. Is the main disk too big, possibly? Should I install on a smaller partition? Thanks.

I am in the market for an used computer for the purpose of having a "Lab purpose" Hyper-V server and I find these CPU mark/rating very confusing.
Unlike in the past when things were simpler (286,386, 486, Pen3, Pen4, I3, i5, i7 ... etc,), Xeon series are not all that simple to choose from.
Having said that, what is it that I need to consider? # of cores? Avg CPU Mark? Date that CPU was released in the market place?
For example Xeon E5-2640 @ 2.50GHz w/ 6 cores has highest Avg CPU mark of 14682 from the list below, but it has 6 core. Now compare it to Xeon E5-2660 @ 2.20GHz w/ 8 cores, but Avg CPU mark is only 11098 even with 8 cores.
Xeon E5-2609 v2 @ 2.50GHz has 4 cores and is the most recent release date of Q2 2014, but Avg CPU mark is only 5149.
Xeon E5-1620 @ 3.60GHz has the highest GHz, but but Avg CPU mark is only 9055.

Just finished a new build today here are the parts.

OS: Win 10 Pro

CPU: i9900k

Cooler: Noctua NH-U12S

MOBO: ASUS TUF Z390 Plus  

RAM: Crucial 4 x 16gb:

SSD:  Samsung 850 Pro 5112gb

GPU: MSI GeForce GTX 1080

PSU: Seasonic 850W

Case: Cooler Master HAF 932

Monitor: Phillips BDM43OUC 43” 4K

After all was installed, I turned it on and got this image.
First Boot
I went into BIOS and did not recover the BIOS setting, but I did disable the RGB lights and change the boot order to DVD so that I could start installing the MOBO drivers etc. I put in the MOBO CD and rebooted.

After booting the next screens were the following images, telling me to press ENTER because it detected the Bootable CD.  I did and it continued on, not reading my cd and ended with a FreeDOS prompt.

I need to learn embedded software and hardware development life cycle and use it to create electronic hardware/software component.  I need to approach this job systematically.  For example, what is the order of tasks.  Probably requirements should be gathered and documented.  Then, what's next and so on?  At what stage should we select hardware components.
Can any Expert tell me if Dell has an ombudsman? On YouTube there are many videos that suggest that "If it were not being filmed nobody would believe it". I am in the middle of such a situation with 1.5 year old $5,500. workstation that has been out of service for several weeks now. Even though I am dealing with a "Resolution Manager" it is an upsetting comedy of errors that is truly unbelievable. I need to step it up and determine if I can get assistance from an ombudsman, if one even exists. I need a clue as to if one is in place at Dell. Experts?
