View Full Version : Screen flasing and slow PC

02-02-2009, 07:42 AM
Well, 2 days ago I reinstalled my OS and now once in a while my screen starts flashing on and off and my PC runs very slow. I think this only happens when I start gaming but I'm not 100% sure. This has never happened to me before.

My specs are:

OS: Microsoft Windows XP Professional
Intel(R) Core(TM)2 Quad CPU @ 2.40GHz
ATI Radeon HD 4870
500GB Hard Drive
Realtek HD Audio

My PC is about a 1 1/2 years old but my video card is around 4 month old I think.

Did you reinstall all the drivers? Motherboard and graphics?

Ohhh don't like the sound of that.

i had the same problem after a capasitor blew on my 7600gt

Games would run for a bit then artifact, buzz out, then whole comp would stop and when running windows screen would flash and so on.

if you have onboard graphics try running with that and see if there is any difference, if not check your graphics card for damage or try reconnecting it. if it works for a while then starts doing it again could br a tell tail sigh
