Hey. I was watching a film in Media Center yesterday and suddently it just froze. The picture on the screens (duel) stayed the same and I could not get my pc to respond to anything, not even Ctrl Alt Del. So after giving it a min to see if it would recover I decided to restart it by the power button but it just turned off at first touch. (Usually have to hold for a few seconds).. Ever since then, when I power it up, all the lights and fans go on but then instead of the sounds im used to, the fans seem not to speed up as much and then nothing else happens. No beeps, fans at constant speed, no signal to the monitor. etc. Has anyone got any idea what the problem might be? The green light is on, on my motherbored suggesting that power is getting to it?? i think.. I had the power supply replaced a couple of months ago as I had a simular problem before. But before the fans did not turn on, so I doubt its the power supply.. I will try and get the details of my machine filled out on my profile soon, but im not sure on the exact details atm as i cant start it up. Any help or advice would be appreciated. cheers.
