I haven't had any problems since installing XP I have Athlon 1.2 Geforce 3 video card 512 memory all about or less than 1 yr. old & I had the system built at Maplins - more or less! Today it just refused to boot up. All I had were dark blue lines across a blue screen. My son opened it up & reset the Cmos & then everything was OK. Please can someone tell me why this happened as if any hardware is about to fail ie. motherboard, processor, graphic's card, I want to return them before warranties run out! The only other time he had to reset the cmos was when I was trying to install XP & had to swap the graphics card with an older one! Just couldn't install XP with the Geforce 3!!!
