Alright so I upgraded my computer today. Whats new: Abit IP35 Intel Core 2 Duo E6750 OCZ "Reaper" DDR2 800 4-4-4-15 So when I first started it up, it turned on for roughly 3-5 seconds, then turned off for 3-5 seconds, then turned on again, and ran. It POST'd, got into Windows Setup, but stalled on Loading windows executables. So I was like wtf. I turned it off broke the system down again and just double checked all the cables, everything was fine, one cord was kinda tight, so I added another cord to make the connection easier. Turned the computer on again, and once again it turned off for 3-5 seconds, then it turned on again, and got stuck at the same point. At this point I throw in Ubuntu 7.04 to try loading that to make sure it's not the XP cd or something, and I see Memtest on it, so wtf might as well memtest it. Errors errors errors. It had found 38 hours within the first 3 seconds. So I'm like wtf, so I am ready to take the ram back, but then I was like wtf I might as well try the other ram bank, and I kinda felt like the ram wasn't in all the way on one of the sticks, but I moved it to the other bank anyways. I turn the computer on again, and once again on, then off, then on again. I figured I'd try Memtest again, and here I am 15 minutes in, and already passed once, and everything is fine. It's still running I figure I'll give it a full hour to run. The question now is why is it still doing the on / off / on? I've built dozens of computers, and never once seen or heard of anything like this. I've heard of on / off / on / off / etc.
