first off here are the specs pentium d 820 intel brand mobo not sure what model 2x512 pny ddr2 crappy 300 watt psu (using a 20 pin on a 24 pin mobo ok so first thing that happened i was testing it on my lap trying to see what was causing such high temps. worked fine. then i went to turn it on with a screwdriver which i had previously been doing. turn it on and i see a little bit of smoke which seemed to have some from a fan power connector on the mobo. it still booted and i went into the bios and everything. then i reset it and no video. so i removed the ram and vid card to see if i get bios beeps and i get nothing so i figured mobo was dead. went to work came back and decided to test it again. booted up and got video. again i decided to restart and what do you know no video. when i plug in the power cable to the power supply it turns on for like half a second then shuts off. i dont even use the power switch it just turns on right when i plug it in. i just started to notice somewhat of a high pitch ticking noise when i plug in the power supply while it is plugged into the mobo even when the comp is off. any ideas of what the hell is going on and what part i have to most likely replace?
