I have been having real problems with my PC.
When powering on, sometimes (and the frequency is increasing) nothing happens at all. I can hear the fan going but the PC itself doesn't begin start-up. Other times I can hear the DVD ROM kick in and the screen starts but then when windows tries to start everything dies and I get a blank screen (fan continues to run). Other times Windows starts but before the log-in screen everything dies again.
Please help if you can. This is driving me a little crazy
