Sys specs:
Intel P4 2.8Ghz Northwood Socket 478
Asus P4P800-E Deluxe
Antec 550watt TRUE550 power supply
2 West digital raptor 74gb drives in RAID 0
pny geforce 6800 ultra OR nvidia 32mb riva video card
Corsair XMS series CMX512-3200C2 DDR400 2x 512Mb (1gig total)
What happened:
I was sitting playing a game one day and my computer just turned off! I pressed the button to power it back on and started up without a display and shortly after powered down again. The latest addition 2 weeks earlier was replacement of my generic ddr400 ram that ran at 266mhz to the corsair memory which runs at 333mhz due to processor limitations at the moment. I gave it a rest and came back and turned on the pc again, this time i got a display and the harddrive activity light remained lite and didn't blink. The system soon shut off after 10 seconds or so. So I started the steps and troubleshooting below.
Steps that lead to problem:
I turn PC on and it boots up into POST then after a random amount of time the system powers off. I've seen it go into the windows emblem during bootup at most, at least ive turned it on and after bout 1 second it turns off. I've unplugged everything but processor, motherboard, video card (both 6800 ultra and riva card), and power supply and still does this as well. I have also tried a different motherboard (Gigabyte GA-8SG667) as well with same minimum configuration AND tried a different P4 northwood processor, the 2.4Ghz model. I have also swapped the power supply with a Enermax 420watt noisetaker and still have the same issue. I've also tried different configurations such as 1 stick ram and dual channel ram as well.
Conclusion:
I think it may be the cables that connect to the motherboard from the case and prehaps one has problem in it?
Any thoughts, ideas, or past possible solutions are welcome please
