pc locks up
Mates got a 1Ghz AMD with Gigabyte 7ZX mobo, 256Mb RAM, Geforce 2 MX/MX 400 video and Ive wiped it clean for him and re-installed XP Pro and updated it to latest version (which Ive done many times). Thing is the PC will work ok for about 10 mins or so then will lock up. Ive tried Nvidia latest graphics drivers and graphics goes off and on whenever you do anything ie black screen for a second then back to normal screen. Have update AMD AGP drivers and VIA chipset drivers but am now at a loss as to the source of the problem.
Thanks in Advance
