When I reset my computer my screen will go blank for like 2 mins and it ( my computer ) will make a high pitched sound untill it finally reboots and goes to the screen that shows ur hardrive and checks your memory and all that. Then it starts windows like normal. Sometimes it takes longer then 2 mins and I have to keep pushing the reset button untill it kicks in. Also opening my cd rom drive sometimes works to get it to go.
It was working fine for about 8 months or so. I was thinking this might have something to do with the motherboard? Isn't there a battery or something that can go bad during temperature changes???
Motherboard is k7s5a something or other, its about 4 years old i think.
