Okay, here's the deal...
My computer is an EMachines T1140
It has a WD400B Caviar 40 gb hard drive with Windows XP pro installed and 128 mb of DDRAM
When I start the computer up, it says, "Windows could not be started successfully" and gives me the options of starting in safe mode, with last known good configurations, and normally. Each one I try brings me to the loading screen for XP pro, then reboots it's self an instant later. I'm rarely stumped here, but some help would be nice. I just need a general idea of what my problem is.
