Problem two: after it had asked me to activate window i reset the pc and changed the boot divices in the bios, primary i changed from fdd to hdd, secondary i changed from hdd to cdrom, and third i changed from hdd to fdd, i then saved and the pc reset, it reached the windows loading screen the the pc reset, i waiting and then it reset again and continues to reset after 7 second of the pc starting ne ideas? i thought maybe the processor is over heating or the psu might not be powerful enough
