Ok at work, I have a standalone dvr machine monitoring and recording everything inside my store and my office. Last weekend, it decided to take a dump on me for no apparent reason and I just figured it was a power supply. BOY WAS I WRONG....

After 3 power supplies, 1 20pins 24 pins adaptor, new case, new cmos battery, whole alot of google and unplugging then replugging everything...


still

NOTHING....

My green led is rapidly blinking in green color. (Supposed to be a solid green)

My power supplies are good because i have tried at  or pulled from other working computers.
Any advice that I haven't tried would be appreciated...
