Earlier today I get back to my computer and it looked like it was frozen, because the mouse and keyboard didn't work. So I rebooted and it got into Windows normally, but the kb/m became unresponsive again. And I new it wasn't the system that was frozen because the connectivity indicator was animating. And each time I booted the kb/m became unresponsive at a predetermined time, whether I was in the Windows sign in screen, the BIOS setup, or running on the windows installation CD.
And in between these times it seemed like it had trouble starting up. Sometimes when I pressed the power button the fan would just give a little wheeze and nothing would happen. Later, pressing the power button did nothing at all.
Then one time I tried unplugging and replugging in the PSU it started acting goofy. Now whenever it's plugged in to the outlet, it emits this high pitched sound. And if it's plugged in to the mother board, its own fan and the CPU fan automatically start going, even though the computer isn't on.
What do you suppose might be wrong with them?
