On two different desktops (one XP, one Win7), there was no video signal going to the monitor, although the power lights came on. The problem was ultimately solved by removing and (in some cases) reinserting the RAM sticks.
On the Win7 computer, I found that the "no video signal" issue returned IF I put either ram stick into slot 3 of 4. So we avoided using that slot, and so far, computer's working fine.
On the XP computer, after I put BOTH ram sticks back into the slots they used to be in, I still could not get the issue to recur; even after I put the ram back into the same slots as before, the computer starts up fine.
Likewise, on a THIRD computer (XP), the startup process was getting stuck on the BIOS screen, UNTIL I removed and reinserted the RAM. Now it starts up fine.
So in the first computer (Win7), I'm assuming the motherboard / ram slot is going bad, probably more problems may come in the future, if the mobo is failing.
But what could account for the 2nd and 3rd computers? Where removing and reinserting the ram fixed a "no video signal" or a "stuck/fixed video image" issue? This article
suggests reseating ram as a fix, so I'm not alone. I guess I"m asking:
(1) How often do you guys try reseating RAM as a fix for such issues?
(2) What accounts for this? Static buildup?
