I have big problems with my computer... For an unknown reason my computer started randomly shutting down for no reason... It is not a reboot, not a blue screen, the computer just power off without any reason, just like if it was suddently unplugged. Sometimes it will shut down a few minutes after i launch windows, sometimes it will last an hour or two and then will shut down suddently

I tryed many thing without success

- Tryed to change my power supply
- Tryed to change my memory
- Tryed to change my hard disk and reinstall window
- Tryed to change my graphic card
- Tryed to put fresh thermal paste on my CPU
I even tryed to change my power supply wire\power cord

Nothing worked... I have been using this computer for 3 years and never had any problem... I don't understand whats going on

My CPU temperature is normal and my case is very well ventilated. It is not an overheating problem

My computer is an AMD Dual Core 6600+ with 4GB ram and 450w power supply. I'm using Windows XP

Since i changed almost all piece of hardware on my computer, i think it must be a problem either with the motherboard or the CPU itself.... I don't have spare board or CPU so i will have to buy a new board and a new CPU.... What should i start with ? Does this looks like a CPU problem or a motherboard problem ?
Also, do you think that updating the BIOS could change something?

thanks for help

I've had this happen to me before. How i solved it was in the BIOS, someone set to turn off every 15 minutes which caused it to turn off automatically. You should have a look in your BIOS for something about shut down timer.

<<Tryed to change my power supply>>

Well...you either changed it or you didn't...did you change to a known good PSU that is adequate for your system?

What PSU is currently installed? What replacement did you try?

When checking the internal components of your system, did you check to see if any of the capacitors were bulging at the top or corroded?

I am working on a system with similar behaviour

Eliminate the cd by removing power & data cables to it.
Clear CMOS.
Check and clean all fans & heat sink.

Boot into the BIOS & let it sit.
If it does the same thing there its most likely the motherboard.
Thats what the one I am working on does. Time factor is completely random too.

IS this a custom system or brand name.
IF brand name please post make/model
In the beginning there was the command line.
