Hi i have just installed a new motherboard, cpu, ram, vga card, and now it is all up and running, just, every time i install a new program, it will boot up to the XP start screen, then blue screen for a fraction of a second, shut dowm then restart and boot ok, but then when it gets to the desktop, either the vga card or audio card will say they both have corrupted drivers. I have found that if i then reboot the machine again, the issue seems to repair itself and everything is fine. Hoping that someone out there has got some advice please, and, as this is my first time,,,, be gentle with me! LOL.
