If I shut my PC off, the next time I try to boot up, it freezes on the HP blue screen (does not make it to Windows XP screen). This has been going on for a couple months now.
If I shut my computer off, unplug it from the wall for 10-15 seconds, plug it back in, it boots up fine.
So, I either have to never shutoff my computer, or unplug it before I start back up so it boots up.
Replaced the power supply, still had the same problem. Put old power supply back in.
Unplugged the hard drive and booted, still had the same problem (don't think its making it to the HD in boot).
Unplugged the DVD rom and CD-RW drives to eliminate them, still had the same problem.
Now, I have a new, related problem, happened first time 4 days ago, now happen a few times a day. The computer shuts down, not a normal shut down, just instantly to blank screen no power on PC. Again, if I unplug for 10-15 seconds, it will boot back up (though sometimes I have to try the unplug trick 2-3 times to work).
Any ideas on what this could be?
Could a bad motherboard cause this? Heat sink?? (note I am an experienced beginner in computer skills).
My fan is running. Actually, it runs all the time. Hardly ever shuts off.
Computer is in a hutch. Door is closed but cut hole in back the size of the tower so fan blow out the back and there is 2' of space between the hutch and the corner walls.
What about something as simple as the CMOS battery
