Windows 7: Screen goes black, then on again.

Right, here is the full story as I am having no luck:

On Tuesday, while busy working, my screen suddenly goes black. About 3 seconds later its on again. In the background I hear the 'device plugged in' notification from Windows. A while later this happens again. And again and again and so on.


Today, Thursday, the problem is still there although it seems to have shifted slightly. The screen still goes black as I mentioned earlier however it only seems to happen when I use a program with a white background eg. browsing certain forums and websites that have white backgrounds or using my design software to create technical drawings. Another thing I noticed is that very often is that the keyboard seems to stop working intermittently, again this is accompanied with the 'device removed'/device plugged in' notification. This happen quite a lot is very annoying, not to mention cutting into my time.


Steps I have taken so far:
  • rebooted PC
  • switched off PC, unplugged everything including wall socket, and held in on button to properly lose all charge.
  • Changed batteries in wireless mouse.
  • Plugged in one device at a time to find guilty one.
  • Changed keyboard.
  • Switched monitor cables HDMI to DVI
  • Reinstalled graphics driver


None of these helped. I don't have a back-up monitor so I can't check that. I really need to find a fix for this. All help appreciated.

I know it's like a rat's nest, but you might try delving into the System Event logs to maybe fine a clue.
The unplugging device sound still make me think for some reason the machine may be powering off? When it comes back on the device gets plugged back in.

You might try monitoring your power supply with HWiNFO, HWiNFO32 & HWiNFO64 - Hardware Information and Analysis Tools, Click the Download Now, next window the Download Installer for your bit version.
It has a logging feature to keep track of the values. Run it in Sensors Only, scroll down to the Volts section, may be under Nuvtron, to see what the volts are reading.

Are you running IE11?

I'm having basically the same issue under Windows 8.1, which obviously is running IE11. Anyway I ask because some think it has to do with an IE11 update. Which?... I'm not sure.

No I use FF. Just unplugged the graphics card, took it out, cleaned the contacts and reinserted. Testing again. If it still doesn't work then I'll have to call my IT guy tomorrow...

Good luck. And unfortunately, your issue could be caused by a myriad of things to include a failing PS to a failing GPU, and everything in between

Hopefully you get it sorted.

Peace

Okay, took out the graphics card, cleaned it up (very very dusty; spiderwebs in case too...) and reinserted. Changed keyboard too since I think the original failed (only 14 months old though). So far so good...

UPDATE: IT guy checked out PC, ran all sorts of test, couldn't find any problem. He thinks it may be the power as that was the only different factor. Ran extension cord from another room and hey presto... all problems gone. Recently bought a UPS, plugged it into original wall socket and all problems reappear. Weird, I thought the UPS would iron out any current issues...
