I fixed one like that last month. The owner didn't take the free advice to put two more drops of heatsink compound on the CPU. They gave up and I did it for the 50 buck minimum charge. They were not happy.
I'm unsure why some don't try the easy stuff first.
There is also an issue with memory, bios, timings and more but I will not write more than that here. It's far too deep and in short a warranty+support problem.
I have an ECS P45T-A with E8400 and 4GB Gskill DDR2 800 kit (2x2gb 5-5-5-15 @1.9V) running vista 64 hp sp1. If I run both sticks of ram in it, it crashes randomly after about 10 min in windows or before boot. I have troubleshooted using either stick of ram alone and they will run 100% stable for days using only 1 chip in any memory slot. This sounds like a mb issue to me what do you guys think? Please let me have some tips, Thanks
