Hello. I've believe i've posted here before, but I'll try again.

Since the first time I turned on my computer (buildt it myself, with a friend, and a little help from my dad), I've had these annoying startup problems, which have led into bigger problems sometimes (sometimes required a format).

Every time I start up after a couple of hours with the computer turned off, the computer have been rebooting as soon as I can see the "STARTING Windows" screen. My options are "Launch Startup Repair" and "Start Windows Normally". Start WIndows Normally have been working sometimes, but I've also had to go into Startup repair, and do a restore. I've lost the count of how many times I've restored. Also Startup Repair terminated my password file, leaving me unable to access my computer. This required a reset/format.

I have tried everything I can. I've formated like 6 times in half a year, yesterday I switched for IDP mode to AHCI mode in BIOS, I took the RAM out and in, I've tried plugging out all the cables from the motherboard and plugged them in again, I've tried the Windows Memory Diagnostics(it's WIndows, so it wouldn't help anyway). Also my HDD failed cus of this problem once, had to buy a new one.

I am so tired of this problem, I just want to throw the computer off a cliff. Also EVERYTIME I take the computer with me to friends, or LANs, the computer gets a little worse than earlier that day. This is so annoying.

Does anyone know what the problem could be?
The processor is working.
The graphic card is working.
The HDD is working.
The RAM should be working, as the computer runs great when I get to turn it on.

Could the motherboard be the problem? I remember, when I built it, we took off a part that was needed for the processor to STICK to the motherboard. We hade to screw it back on, and it was as good as before. But maybe we touched anything we shouldn't touch at the motherboard? Should I try send it in to ASUS, my warranty will cover it.

Also I've tried installing another Windows. Did not help.


Thanks in advance.

ForgeDid you apply thermal compound on the CPU heatsink when assembling this PC ? ?

Thermal Paste Guidebuddy there may not be proper cooling for the processor or a prob with the heat sink assembly...by da way check the cooling paste on the processor even that could cause a lot of problem.. Quote from: ananth on April 20, 2011, 09:47:56 AM

What do you mean?

some of the paste went over to the processor, could this be a problem?

No...that shouldn't have caused your issue...but read thru the guide thoroughly for proper removal and reapplication procedures...
