LOL...we don't hiss or elevate Mac users to archvillain status here
. Most of us have realized...it's a diverse place, this world...which is why Mac users can now run Windows
My first suggestion...uninstall Advance System Care.
System manufacturer and model?
Any "reinstallation", "recovery", "installation" CDs available for this system?
Can you boot into the BIOS? Does it reflect a hard drive properly?
Just a tip...the way to correct problems with a PC...does not often involve paying for additional software of any sort (other than possibly Windows).
Those "Not Found" messages could indicate a BIOS/CMOS battery problem. Does the BIOS reflect the correct date/time?
