Hello,

 

I am writing for some assistance on troubleshooting a strange problem where the monitor reports a loss of signal but the speakers of the youtube/netflix continues playing. A quick power down resolves the issue. Sometimes its happen 5-6 times in an evening again while watching youtube or netflix videos. This is a Windows 10 PC from the Asus manufacturer. It has a Nvidia Geforce GT 640 video card. I have re-seated all cards and memory. I have reapplied the thermal paste on the video card. The latest trick I tried was a full removal of the video drivers. After all scenarios the issue still repeats itself each day. A friend suggested buying an expensive video card to replacement the current GT640. Any ideas folks?

 

Thanks so a bunch!

Have you tried another monitor with different cables?

Are you able to try another video card without having to purchase a new one?

 

Try these free hardware diagnostics:  http://www.carrona.org/hwdiag.html

Please start with the video tests (Furmark and the Video 2 tests), but please complete ALL of them and let us know the results.

 

Also, please let it lose the signal one more time, then recover and immediately generate these 2 sets of reports:

Report Set #1)  Please run this report collecting tool (even though you may not be experiencing BSOD's) so that we can provide a complete analysis: (from the pinned topic at the top of the forum)   http://www.bleepingcomputer.com/forums/t/576314/blue-screen-of-death-bsod-posting-instructions-windows-10-81-8-7-vista/

If you have problems with it running it, there's an alternate tool here (direct download link):  https://github.com/blueelvis/BSOD-Inspector/releases/download/1.0.5/BSODInspector-1.0.5.exe

NOTE:
Please zip up the (.ZIP) files - do not use .RAR or other compression utilities. 
.ZIP is the type file that can be uploaded to the forums.

Report Set #2)  Please do the following:
- open Event Viewer (run eventvwr.msc from the "Run" dialog)
- expand the Custom Views category (left click on the > next to the words "Custom Views")
- right click on the "Administrative Events" heading
- select "Save all Events in Custom View as..."
- save the file as Admin.evtx
- zip up the file (right click on it, select "Send to", select "Compressed (zipped) folder")
- upload it with your next post (if it's too big, then upload it to a free file-hosting service and post a link here).

FYI - If we're looking for Event ID 41 errors (unexplained shutdowns), there's more info on that here:  http://support.microsoft.com/kb/2028504
The Event ID 41 error is simply Windows saying that it doesn't know why it shutdown.

Yes, I have tried a different monitor with different cables, same problem.

 

I am not able to try a video card without purchasing it. 

 

Thanks so much for your prompt response. Here are the results of the various tests. 

 

I ran the Furmark test, and it failed. It reached 98 degrees and I lost signal. As a result of this incident I decided to gather the two logs. Unfortunately, the sysnative app resulted in a blue screen of death. No logs to shared from that program. I did grab the event viewer logs and have attached them for your diagnosis. 

 

I continued with the various Video card tests under Video 2. MemtestG80 failed and MemtestCL was successful. I ran the ISO version of vmt with success. 

 

Let me continue, I ran memtest with success, no errors reported. segate hard drive test finished running again without any errors or problems detected. 

 

Can we conclude that the video card is defective? I am going to assume a low-end replacement (nvidia with just a heatsink vs versus a giant fan/heat sink combo?) from my local computer store should be adequate as this is not a gaming machine. Just used for surfing, youtube and netflix. Please advise.

Check the video card out.  It may be something as simple as a clogged fan not working.
It depends on how comfortable you are in trying to fix the current video card (and, even if you do fix the fan and heatsink, that may not fix the problem that it's having).

 

As it's not for gaming you can likely get away with a very basic card - just be sure that you aren't going to end up waiting for it to buffer all day long.

I'm not sure about the differences (as I'm not a hardware expert).  I'd suggest posting over in the Internal Hardware forums for a more knowledgeable opinion:    http://www.bleepingcomputer.com/forums/f/7/internal-hardware/
