My Monitor Keeps Losing Signal During Gaming

post #1 of 43
Thread Starter 
When I play games i randomly get a no signal message on my monitor which requires a reboot to get it to display again. One time when it happened it would not display until i switched the power off on the psu and turned it back on again. Also this happens when i try to run the windows experience index.

Things I tried and what can be ruled out
-tried different cables and different ports on gpu
-lowering settings on games
-ram is stable when running memory intensive things like video rendering
-gpu does not overheat it stays within normal range not going above 65C under load
-putting it in different pcix16 slots
-updating bios
-updating to latest amd drivers and downgrading currently (13.1) tried 12.4 and up so far.
-made sure cable is snug
-tried it computer directly plugged into the wall.

This could be something that can be RMA'ed. I used to have a similar problem, and it would only happen when the card was under load, same as you. This is just my thought, maybe someone else can give you some further advice.

Dude I just ran into this issue with 7950 through Hdmi and win8 first try hooking up through VGA via dvi to VGA adapter if it stops then we have same issue. I use a 32" tv hooked through hdmi and for some messed up reason my refresh rate randomly switches to 22hertz in gaming its extremely weird.

I ordered a power supply tester from newegg. I will test my psu and if it passes then the 7950 is going to be in a box on its way to Cali. I will update when i get it. Post if you have a similar issue or found a fix or if i forgot to try something. Also I ran 2 passes of windows memory diagnostic with no errors so right now everything is pointing towards the psu or gpu. Is it possible the monitor is the problem? Thanks in advance smile.gif

No It's not already made sure it only doesn't it in windows 8 which doesn't bother me cause windows 8sucks so just went back to 7

It could be a unstable processor cause loads will kick me in the teeth too try giving it a bit more voltage on the cpu

Don, t think its my cpu because when I tax it with rendering videos it remains solid. It only happens in gaming situations which only use a portion of my cpu. Also my gpu cant run the wei without crashing

Good news. I decided to take my computer monitor and computer off of my power strip and plug directly into the wall. I was able to run the windows experience index without it crashing. The first time since I built my computer in August. I now have to test my computer operating directly from the wall outlet. Maybe my power strip wasn't providing enough power. Will update once I install crysis and a couple of other games I usually crash with. If i don't crash It would have to be the power strip that caused this problem all along. WOW
