text: This could be a number of things. First things first, try pressing f8 at bootup and boot into safe mode. If you can boot into safe mode, it's a software problem. If you can't, it's a hardware problem and you need to take it to a professional. Actually, either way this is out of your hands and you need to have someone that know swhat they're doing look at it. Nowadays, PC Repair technicians charge so damn much, it's almost worth it to buy a whole new computer. So it just depends on whats wrong with it. Time to call that geek in school you never talked to. Good luck.
