Howdy all, when starting up my HP Media Center PC (2.4 Ghz with 4MEG Ram,
Vista Home Premium with SP1), started my account. Once I started...the
screen would come up and the task bar would come up, but then the system
hangs. Tried to use a different restore point and no dice. Cleaned up disk
drive in safe mode, but won't let me defrag. No error messages, nothing,
just hangs up and stays there. I'm concerned this is a hardware problem.
Any suggestions or thoughts before I go and spend $ on having a pro fix it.

Thanks
