Hello,
I'm having an incredibly frustrating problem right now. The machine was running for 3 days PERFECTLY, at 3.1ghz with 33C under load @ 1.53v. Yesterday, I rebooted it, and it hung at the post screen. I did a hard power off, reset cmos, popped in one sitck in the 3rd orange slot, and turned the machine back on. IT posted, but gave me a CMOS checksum error. I proceeded to load up windows, where it acted REALLY slow for some reason. It was so slow that I did another hard power off, and thats where the machien died. It quite simply will not post no matter what I do.
The exact symptoms are as follows:
1. hit power button on board OR case
2. All 4 LED's flash on and off instantly once.
3. Machine just sits there and fans whir, hard drive churns a bit, and no post, no led's.
These are the things I know so far
1. Bios chip is not the problem. I swapped it out with another known good from another expert I own.
2. Power supply is not the problem. Aside from the fact it's the second best power supply in production fpr high draw systems, (it beats the pcp&c 850 for SLI configs due to single high amperage line) the voltages check out fine on the multimeter. Tried with Antec 550, same problems.
3. Watercooling is not the problem. It worked fine for 3 days, no leaks, nothing.
4. Shorting is not a problem. I installed all the motherboard standoffs correctly and nothing metallic is in contact with the motherboard.
5. Ram is not the problem. Same symptoms with the following ram, I tried all of the following as individual sticks and dual channel: 4x512mb mushkin redline xp4000 (2GB), 12x512mb OCZ Platinum pc3200 2-2-2-5, 8x512mb Corsair Valuram. None work.
6. Video card is not the problem. Despite the voltmods, it ran at 38C full load. Tried with voltmods removed and on, no difference in motherboard. Also tried one of my 7800GTX 512mbs in the board and it did not work.
7. interestingly enough, I can get the 4 leds to stay on if I unplug the 8pin connector from the motherboard. However this obviously causes the board not to post in and of itself, so its not much help.
I have all the obvious stuff done right; power connectors are all in, tried cmos reset, battery out, etc, etc.
At this point, its either the CPU or the motherboard in my opinion. It is unlikely that it is the cpu simply because it was working fine and under such superb cooling. This is supremley frustrating and I would really appreciate some help. Thanks in advance.
