a few days ago i my onboard lan card suddenly dissappeared in windows and in the bios after the computer had been on all night. I restarted several times after this with no problem except sygate crashed everytime untill i reinstalled it. Then my computer restarted spontainiously and froze on the windows screen. after i restarted, windows booted then it restarted again. I cleared the cmos. The computer would post and enter bios, but freeze. Now, with he ide's unplugged, my computer will only post after sitting untouched for several hours then freeze before i can get to bios. If i have attempted to boot it the fans will spin, but i won't get a beep or display.
i tried a different psu but the best i could find was 300 watts
i tried clearing the cmos via the button and leaving the cmos battery out all night.
i tried starting the computer after taking each peice out untill i had only the motherboard and psu and never got any beeps
i noticed that sometimes the computer will start after it has power even when the front panel power button is unplugged, even when the motherboard is sitting out of the case on a wooden surface.
I don't have any other parts to test with.
I tested the +12 and +5 volt on the psu with a multimeter, but couldn't test anything else.
Does this mean the motherboard is dead? Is there anythign else i could try?
