Hi all, I've got a issue thats got me stumped. I recently just put in a new video card, but the next day when i went to turn the computer on, nothing happened - no lights, no post, nothing. There are lights on the motherboard, so there is power getting through. I read somewhere to try and short the power pins on the mobo, this didnt work either. I unplugged the PSU for 5 minutes, plugged it back in...and now it turns on! Problem is, every time i power down the computer now (resets work fine) I run into the same problem. Any ideas why this would be? I've got a Silverstone strider 850w PSU thats less than 18 months old.
