i just bought a mobo k7s5a pro, an athlon 2000+processor and a maxtor 40 gig hard drive. i am able to install win 98se onto the hard drive but when i try to upgrade to xp, i get an error message that says the C: drive is corrupted. i bought another hard drive and still got the same error message. i tried another copy of win xp and still got the same error message. what is wrong here? HELP!!!!!
