I tried to install a gpu on my pc and it wouldn't post. Now whenever I start the system it turns on and off and off and so on for two minutes. I tried removing the battery pressing the clear cmos button and shorting the jumper with my keys for 30 seconds (the battery was removed when I did this). My mobo is a msi z77a-g45 with a 3570k.
