Please can anyone help me with this one: My PC's had it and needs a format but I can't start it to format it. It does a memory check and says 'press del to enter setup' but then goes black. The fan is still running, nothing beeps and no lights come on on the keyboard. I'm running xp and have tried F8, starting with the disc in to boot up from cd and even trying del to access the bios but it dies every time. Any suggestions?
