Note it's "no longer", but it used to POST into BIOS - twice.
I already requested RMA and the nice Egg rep waived all the fee for me. But I am so curious how could a motherboard failed in this way?
Here's the story. Just received Q6600 G0 yesterday. I tested it first with my old system.
P5W DH Deluxe: BIOS 2205
Corsair XMS2 2GB kit DDR2-800
ATI X1800XT 512MB
... omitted.
It worked just fine, PRIME95 25.3 one hour no problem. Core temp 65-66C. Then I try a little OC to 300FSB (266 default). POST but hang after booting into Windows. Then it didn't POST. At this point I know it's the P5W DH problem, because it happen several times when OC. Probably the auto recovery didn't work quite well, just need totally power down. I didn't bother doing that and moved to P5K Premium directly.
Okay I put RAM in slot 2 and 4. X1800XT, and CPU, nothing else. POST very well and go into BIOS right away. Then I connected the HDD, etc. Won't POST. I removed one stick (let's say stick_A) of RAM, won't POTS. Replaced stick_A with stick_B (still one stick), POST okay into BIOS. Okay I guess I can try two sticks again as the stick should not suddenly failed in one minute. But from now on, no matter how I sit the RAM (one or two sticks, slot 1, 2, 3, 4, 1/3, 2/4), it will not POST at all.
Clear the CMOS. Still no POST.
Move CPU/RAM/video card back to P5W DH Deluxe, boot into Windows no problem. Back to P5K Premium, no POST. Tried several times so is pretty sure it's P5K Premium's problem.
If I totally cut off power and stay power down longer, like 5 minutes, then at first few trys, the CPU fan will turn for a quarter second, then stop like it's dead. After a few tries, the CPU fan didn't turn at all. I waited a night, the first try in the morning, CPU fan turned for a quarter second. Subsequent tries, no response at all, CPU fan will not even turn the magical quarter second.
How could a motherboard failed in this way? Which component of motherboard is at fault?
