Possible memory problem?

post #1 of 4
Thread Starter 
Alright, I'm calling out all the bright OCN brains to help me resolve this.

I've been trying to figure out why sometimes I get random no video display signal when turning my setup on after shutting it down. I'll usually shut my computer down at night but then upon starting it back up in the morning, I get no display signal. I've tried disabling onboard graphics, updating to latest motherboard bios, and updating to latest system drivers, but the problem is still unresolved. I had a 7950 on the same motherboard a few weeks ago and the problem was absent thinking.gif Thinking it might be faulty memory, I used Memtest86 v4.0a to test the ram. On pass #2, this mess shows up
but no errors are reported and pass is completed. Memtest is still running as I'm writing this and the mess is still on the screen. Memtest has reported no errors. Regardless, could this be indicative of a memory problem? Furthermore, could this be what is causing my no video signal problem?

HELP

I have had the same mess on the screen happen to me when using memtest86.....but it never seems to happen to me when using memtest86+. You might try that one.

I'm curious as to how you know the pass competed with no errors? Maybe I didn't wait mine out long enough, but I never had any of the lower 1/2 of my screen refresh again after the symbols filled the screen.

I will try Memtest86+ v5.00b1 but would Prime95 blend/custom using 100% of available ram be a more efficient test at detecting defective memory? And is it probable that faulty ram could be the cause of no video signal during start-up? I normally have to restart OR turn off and turn on my computer a number of times to get a video signal. Everything 'seems' to be in working order once I am able to get a signal as there are no operating system errors reported, no blue screen errors, and no impediments whatsoever while gaming or going about typical computer tasks. I may have just received a defective video card thumbsdownsmileyanim.gif
