GIGABYTE GA-7VA motherboard,Amd socket A 2.4 Ghz,DDR PC2700 Ram, Windows XP Pro. My pc will switch off every 10-15 mins. I have changed the case this time with 350 watts, graphic card and hard drive. It still does it. I suspect the motherboard but then again it could be the processor. Any help will be appreciated.
Have you tried removing and reseating all of the memory/pci cards?They can work loose and cause all manner of problems.
Is it possible that the power supply is faulty. On my own home built pc I suffered from months of random crashes and errors leading to repeated windows reinstalations and much weeping and wailing and gnashing of teeth due to a bad power supply.
Thank you both for your feedback. I did suspect the power supply at first, then I bought a new case (350 Watts)but the problem persists. I am using the old case for another system which is fine. I then suspected my Radeon 9000 Pro, so I tried another graphic card, still no change. I have got a PCI scsi and a PCI network card on the system. I will remove them individually and see what happen. As it stands I can't get to windows. During booting up the system will shut down (swich off). I went to the Bios and change 1st boot to CD Rom, I get a blue screen with a blinking cursor for about 5-10 minutes then it will switch off completely.
I have now changed my motherboard to Asus A7V8X-X and would you beleive it the system still switch off during boot up. Sometime it will go as far as loading windows and then it will switch off. I just don't know what to do next. Please help.
