MOBO: ASUS P7P55D-E PRO
CPU: Intel i7 860
Video: Sipphire Radeon HD5870
CPU Cooler: Corsir H50 / Thermaltake "Real Silent"
So I had some bad news when I started my PC yesterday. Immediately after I turned it on I smelled smoke and the computer shut itself down. When I tried to turn it on again it shows a CPU error (on board LED indicator) and shuts off again. So I ended up taking out the hardware to find the source of the problem and I saw that a chip above the PCIex 16x slot has a white speck and does not look like the other chips next to it. see this photo.
A little background... My PC was running ok for about six weeks with the Thermaltake air cooler (CPU temp around 40-50 C). So I decided to go with the Corsair H50 enclosed water-cooler. I installed the H50 on Thursday and ran it for about 4-5 hours with no problems (CPU temp 20-35C). I also had it on for 3-4 hours on Friday with no problems. When I went to start my PC on Saturday is when the bad thing happened.
I'm suspecting the H50 is to blame, but it could also be my MOBO. I'm hoping my $430 video card or my $300 cpu wasn't damaged.
Can anyone give me some info on possible causes? Or has anyone had similar experiences with ASUS?
Did some googling this morning... here is some info on the bad chip:
