Here are the only clues I have to go on right now:
I got home from work and my computer was off--I believe I left it on when I left in the morning. I turned on the computer and it was working normally for about an hour. However I did notice a few issues of having to replug/change a few of my usb ports to get, for example, my flash drive recognized.
After maybe an hour my display went black as it apparently stopped getting a signal from the computer. The computer hadn't shut off, as the led was still on and the fans were all still running.
This worried me, so I hit the power button to shut down the computer and reboot. No response, the computer made no indication to be shutting off. So I held down the power button to force it off.
Now, when I try to turn it on again, it appears to be starting up--the leds light up and the fans start spinning. But after a few seconds it just shuts back off.
Is this typical of any particular component being fried, power supply or motherboard, for example? Any insight on how I can troubleshoot this? Any help you guys can give would be greatly appreciated.
