My PC was acting up on me a lot lately, most of it crashes and freezes while playing StarCraft 2. Mighty inconvenient because that causes me to lose points in multiplayer.

Anyway, after the latest barf, I had enough and downloaded the newest memtest86. Halfway through it went nuts, finding errors in "CPU 0". After 1 million errors all at the same memory location (wish it saved a log), I got the hint.

Since they were all in the same spot, I decided to take a chance. I yanked out 2 DIMMs, in slots 0 and 2. Ran memtest86, no errors. Ok, so, bad DIMMs? I put those DIMMs back in and took the two good ones out. The computer wouldn't even POST.

I switched the same DIMMs to 1/3 instead of 0/2. Booted right up, passed the test with flying colors.

My conclusion: bad DIMM slots. Am I wrong? I won't rush out to replace the motherboard just yet. I can live with "just" 4GB of memory and don't have the spare cash ATM.

Ok I did the experiment. I took out the two that were in there and put the other 2 DIMMs in slots 0/2. Same story, the computer would not even come up to POST. But when I moved those DIMMs to slots 1/3, bam, came right up and passed memtest.

So, bad DIMM slot on the board? Will this degenerate and eventually take out the whole board?

Gigabyte GA-P55A-UD3 mobo
Core i7-860 stock speed.
8GB RAM, in 4 Kingston HyperX DDR3 SDRAM, 1.65 V, Non-ECC, Unbuffered, etc.
ATI 5870 video card
Momentus XT C: drive.
Cooler Master CPU cooler

If I have to replace the mobo I'll probably get a water cooler system.
