Power Outage Problems

I built my PC a couple years ago and most things were going well. It would be a little tempermental (if I shut it down for a few days, it would take a couple attempts to get it to fire back up) but once it was running, there were no issues at all. Yesterday, I lost power for a few hours and when I tried to restart it, it wouldn't even POST. Every fan would spin up and run, but I didn't get any sort of response on the monitor.

After checking individual components, the RAM seemed to be causing the problems. I have 4x1GB of Crucial Ballistix PC6400, but now only 1 seems to work. The one that works seems to work in any of the 4 DDR2 slots, but the other 3 cause the system to not POST (whether they are used alone or in combination with the working stick). Does this seem like a logically possible response to a single power outage? The system was on a surge protector, but it is just a basic one. Is there another possible problem with the system that I am not considering, or is it assuredly the RAM? Should I assume all of the other 3 sticks are dead?

Any help would be very much appreciated.

System Specs: Q6600, P35-DS3R, X1950 Pro, Corsair 550VX, RAM listed above.

Put the one stick in and go into the BIOS. Check the voltage going to your RAM; you may need to increase it a little. The default is 1.8V, but that Crucial may want more.

The problem with attempting this is that I cannot POST with the other sticks of RAM. So, I can't test the other sticks since it never reaches that point.

I did test the one working stick and it worked without a problem.


To the other suggestion: I don't think I had to raise it previously. Could the power outage change the power requirements?
