my wc system went belly up so a few days ago I removed my mobo on its tray, replaced the block with a HSF, and took the drives out in their rack, and set up a temporary "base" on my desk. that worked splendly. today I put it all back in my case. now it wont boot. it spins the fans for a milisecond, the HD light blinks very qucikly, then nothing. this is a common problem I know, but for the life of me I cant figure out whats wrong. ive tried stripping it down to the mobo, same result PSU is an Antec 412, not even 6 months old. Help please!
