Video blinks out.

[mlynch1958]

I have a machine whose video keeps blinking out after 4- 5 minutes. The CPU is still running, and the monitro is on, displaying it's "no signal" screen. When i reboot, it comes back up, but then blinks out again. I've replaced the video card, which fixed it for about a month, but now it's back. This doesn't seem like a monitor issue, but I suppose it could be. Could it perhaps be an overheating issue with the MB? A memory issue? I replace the power supply on this machine not too long ago in response to total blackouts.
Any ideas would be appreciated.

First off :wave:Welceme to TechSpot:wave:

It could be a bent pin on your monitor cable or video output. If it is still happening after you changed your vid card, and it is continuing it sounds to me like it is a heat issue. Check to make sure you are getting proper cooling into and out of your case.
