Hi, I have a media center PC in my living Room. On waking up this morning I discovered that the PC had completely locked up. When I reboot I just get the message, there has been a hardware failure. I select the option to boot with the last known good config, the PC goes away does some work and then returns to the same screen. If I select Boot Normally it just boots to a black screen and goes no further. In inserted the install CD and after it has gone through the load files sequence I get a message asking me to insert the install CD and select repair (eh! :). I appear to be in this hardware failure boot loop and can not get out of it. Any ideas what hardware could cause such a complete failure. I was thinking MB but if the PC is booting (to a degree) so I would tend to think the MB is OK. Any help or ideas would be appreciated. I have a WHS backup of the machine so if I have to blow everything away I can without to much of a problem.
