I'm trying to sort out a friends HP Pavilion Desktop PC and well this is the problem... You start it up and you get to the opening HP screen with the usual options, but nothing happens. I've tried to get into the BIOS but all it says is entering BIOS but nothing happens... Full spec is as follows: HP Pavillion desktop, Intel Core 2 Quad Q8200 Processor, Asus Benicia IPIBL-BL Motherboard, 2 GB RAM, Running Windows Vista Home Premium. I've tried to do a recovery but the machine won't even give the option of the boot menu. I'm starting to think the CPU or Motherboard has gone. My friend did mention he had a virus before it comletely died. Any ideas anyone?
