|Hi to all.|
I'm helping a friend buying a brand new computer.
We got everything and I assembled it.
The computer is random crashing. Sometimes during boot, sometimes right after XP is loaded, sometimes after installing drivers.
The computer goes as follows:
Mobo: Asus P5QL SE
Ram: Kingston DDR2 800Mhz Value Ram
HDD: Hitachi 500GB SATA 2
DVD-RW: Asus DVD-RW Sata
Graphics: Asus ATI4850 1GB PCIex16
PSU: 500W almost new 1 year old, but crappy brand (Might be the problem?)
Testing goes as follows.
Memtest of the same RAM on another computer OK
Memtest of diferent RAM on this computer OK
HDD tested on another computer OK
Didn't test another HDD on this computer, don't have any SATA HDD spare.
ATI tested on another computer works fine.
My old 6600GT on this computer and still crashes.
Tested another 500W PSU on this computer and it crashed. But also not a good PSU. Althou this PSU has higher Amp. on the rails.
Motherboard: Flashed the BIOS for the latest version and still crashes. Faulty mobo?
I don't have any spare 600W or 700W PSU to test if in fact there is PSU problem.
My friend doesn't want to spend money on a new PSU unless we are sure that 500W is low.
What you guys think?
Low power PSU or bad mobo?
