But just when I thought I'd give up, my mate discovered something.
K, he uses this video chatting program on the same PC and for the past week although there were numerous random reboots but it never affected him while he was running the video chatting program. He jokingly said to me that "the computer must like my program".
I didn't take it seriously at first until he forgot to unplug the USB Camera (a dinosaur-aged Microtek Take-it 350) and the computer didn't shut down for the whole afternoon. So I decided I'd wait and see.
Left the computer on before I went to bed last night, got up this morning, checked the computer, it's on! Hasn't rebooted itself! That hasn't happened for at least the past week.
Strange isn't it? Could someone explain it? I mean the webcam is connected to a USB extension cord coming from the back of the computer and by leaving the camera plugged in it's been suppressing the PC's random reboots? Does that make logical sense?
Thanks so much guys~
PS - Gonna be a busy day today but will check replies this afternoon, cheers.
