I have a Compaq PC with windows xp installed on it. until recently it worked fine till it crashed. when i recovered my PC it worked fine, that is until i tried to reinstall windows service pack 3. then it started to blue screen on boot up, which was the original sign that it crashed. the stop message says something is going on with the BIOS as well as this
stop: 0x0000007e (0xc0000005, 0xBA258756, oxBA4C342C, oxBA4C3128)
Any tip on how i could fix this myself without spending money on a tech specialist?
