I'm new to the board, so please ignore my apparent lack of hardware/system knowledge.
Computer: HP Media Center PC
OS: Vista x64 Home Premium Edition
As of recent, my Desktop PC just locks up. What I mean by that is after a random number of minutes of inactivity, the screen will be blank and any/all my lights on the keyboard will be off. I have tried pushing down on keys or moving the mouse as if the machine was "asleep", but to no avail. I have to hold the on/off button for the typical 5 seconds to turn off the CPU.
Any forward guidance on troubleshooting or maintenance would be greatly appreciated and please be patient with me..
Now, if you have any questions on classic Mopars/Dodges, I'm your man..
