Windows 7: PC screen suddenly flashes to a black screen and back

Hi windude99...no..it is not fixed yet. I have run my AV and the Malwarebytes already, and nothing showed up. So don't think malware is the problem. And I keep my machine clean and don't play in chancy, unknown or unsecured playgrounds on the Internet.

Thank you for your time and help, it is much appreciated.

Hi Tink, et al,
For what it's worth, I doubt the problem is related to either of the events posted above. I was going to second windude99's idea to check for malware, but see you already have. (Of course, just because scan came up clean doesn't mean you're not infected...)

At this point a physical-connection issue seems reasonable:
- Bad video cable
- a connector not seated
- bad/broken solder on that brand-new MB.

I'd try gently wiggling video cable at both ends, or rock the Slimline tower/case slightly to see whether that provokes the problem.

Luck/Cheers!

Thanks, smopuiM. I will check the items that you mentioned and see what turns up. I have switched the PC connects to my duel monitor and so far no flashes. However, as they are random, it is hard to tell yet if that might have helped the problem. But, just one more thing to troubleshoot. Ya nev'a know.

You might have some luck here:
C:\Windows\System32\eventvwr.exe

Cheers.
This is the cheerful moment...

Well all....it appears that switching the connections to the dual monitor has resolved the problem with the flashing on and off. There has been no new incidences of the random flashing since I switched the connections. Both were secure, but, not sure why one works and the other didn't for the new PC. Same type of cables, same type of connection. But, at this point I am not going to question it, just be thankful it has stopped. The other PC does not have any flashing issue now either, so I guess I can say the problem has been resolved. At least for now.

Thank you all for your time and help, I truly do appreciate it. Maybe this will help someone else who runs into the same or similar problem with the newer HP Slimline desktops.

I have the same problem

My screen was working fine, nothing was changed on computer, I even tried on my other computer... it's the same thing...

Please don't bother talking me about virus or something else like this... I don't want you to waste your time or mine... The problem is material related and not like the other guy ones... I already tried to change my port. It's the same problem but not the same solution...

Thank you for helping me!! It will be greatly appreciated

Screen goes black for a second then back on without any error messages
Screen randomly goes black then comes back on, no message saying display driver has stopped working. Happens every 10-15 minutes. Fresh install of windows 7 too. Anyone has this problem before? Should I try re-seating GPU?

Windows screen flashes, random grey screen & random black screen
This is driving me crazy. Right after I boot my laptop, the screen flashes randomly. Also something is stealing focus from what I am working on to something else. Then it likes to suddenly go to a grey screen. I have to manually reboot. If that is not enough, it like to just reboot.
