Purchase a good power supply and install it.. If you have a brand name machine, they are usually underpowered.. You'll want to purchase a good PS with more wattage than was installed at the factory.
Next, try reseating all PCI cards, RAM modules, the motherboard, etc.
Although my next step would be a motherboard replacement, if the above steps don't fix the issue, I would reformat and reinstall Windows, just in case it's a software issue.. I don't think it is, but at least reinstalling the OS is free.. If that doesn't get it done, try the motherboard..
Hope this helps.
alright, first off just to turn the thing on i have to switch off the power supply for 10 seconds, then switch it back on. Then sometimes it will freeze loading winXP and starting in safe mode doesnt help. After the miracle of actually loading up windows, the USB drives turn on and off constantly as does the mouse, and suddenly windows no longer detects the network card so i cant connect to the internet. I am thinking it is a problem with the power supply but i was wondering if there was any other problem i might have missed?
AMD 2 ghz
oh yeah and spybot, virusscanners, etc come up with nothing .
thanks for any help
