Hi, got a bit of a problem on my hands. My PC has been working perfectly for a couple of months now. Have an Asus m2n-e mobo with W.D hard drive, partitioned into 2. Last night i tried to shut down the PC and left it alone, came back into my room and found it hadn't shut down properly, as i could still hear the fans running. Found that it couldn't end program 'XPCOM.exe', which i now understand is a part of FireFox, which leads me to believe that this has nothing to do with what the actual program is. Anyway, i ended the program, and it still didn't shut down, as it just stayed on the light-blue xp background with the cursor (no icons etc), so had to shut down by keeping the power button pressed. This morning when going to power on the PC, it gets to the mobo manufacturer logo, and does not proceed. It just sticks there. Even says press TAB to see POST data (i think) and press DEL to enter setup, but it does not allow. So basically, i'm stuck there and the only thing i can do is power off, and go round in circles. Won;t even give me the option to boot from CD! I'm guessing what happened last night has nothing to do with whats happening now as it's probably just a coincidence, but i need my bloody PC back on! Any ideas anybody?
