Did a lot of looking on here and found some threads that i read but none helped. Ill start with my build: AMD Fx8320, Gigabyte 990FXA UD3 (Rev 4.0) MSI R9 270x, Corsair cx750m, Kingston hyper x 16gb memory 1600mhz, Kingston Hyper X 3k ssd,

The build is only a week old and was working fine till this morning. When starting up, i push the power button the computer turns on, then rapidly shuts off for a few seconds then turns back on, after which it boots fine most of the time. Some times i get the "your computer encountered a problem which caused it to restart" screen and it starts the process over but most of the time it will boot up.

Any one got any ideas why it shuts off then boots fine afterwards? Its annoying and sometimes i get the "collecting data" screen and restarts.

Dont think its a short in the power buttons as soon as i turn it on i unplugged the power button from the mobo but it still does the whole shut off and restart, i also unplugged the reset button, This just started this morning please help,

Merry Christmas to you all!!

Check your windows logs for any error, warning, or critical; entries to get an idea of where the problem is. When it shuts off has windows already turned on or started to turn on or does it restart during the motherboards post tests too? maybe a hardware diagnostics test would be a good idea to make sure everything is functioning properly. Have you updated any drivers recently?
