Yes, Simple answer is to go into BIOS and reset all settings to default (on some BOS they have a fail-safe setting, load that) and see if that helps. If not, assume its a driver problem. If you are running Windows XP, reboot from the CD, choose NEXT at the first screen, ACCEPT the EULA then choose Repair for your current OS drive. This will delete all windows critical files BUT NOT USER FILES and it will re-install a fresh version of windows with fresh files. See if that helps.
NOTE: Some drivers will NEED to be re-installed afterwards and when the PC loads up into windows, ALL your programs and Documents WILL STILL work fine. It will not format your system or remove any program critical files.
