Last night my computer froze as I was using Firefox. Unable to shut it down normally, I powered it down. Today, I turned it on, expecting it to either come up normally or scan the disk, what it normally does.
Instead, it hangs at "Initializing USB Controllers..." at POST for about a minute or so, then hangs at a blank screen with a flashing cursor for another few seconds. It then goes to a Windows boot selection screen, and I choose "Last Known Good Configuration". It takes me to the Windows splash screen, where the bar goes across the screen for a little bit. The computer then stops loading and returns to the initial POST messages.
The setup is:
Aspire X-Dreamer II case
Pentium 4 3.0 Ghz
Asus P4S800D-X mobo
ATI Radeon 9600
512 MB PC3200 RAM
WD160JB Hard drive
I haven't changed any of the hardware, although the front temperature readout has recently malfunctioned.
Any idea why this could be happening?
