I am trying to reinstall windows xp to fix a major virus/spyware problem on my daughter's computer. The system will not boot from cd. I have tried the disk in another system, and it works fine. I have tried three different cd drives, no change. I have swapped the ide cable with a brand new one, no change. I have swapped ide ports on the mobo, no change. The drive does appear in the BIOS, and I have set the cd as the primary boot drive. I have even disabled the other boot drives. (All this gets me is a system beep and a message to press F1 to try booting again.) The drive does not spin at boot, but it spins endlessly when I try to look at it using windows explorer. This is an older Dell system with a P4 1G chip on what appears to be a Dell mobo. What next?
