Hello,

I have just upgraded my computers motherboard and CPU.

Asrock H77 pro4/MVP
Intel i5 3570
2* 4gb corsair vengeance 1600mhz ram
GeForce 550ti superclocked
500gb hard drive with win7 64bit OS installed

I have tried starting the system with only the CPU, HDD and ram installed but still no result.

Please help.

See if the system will post without the hard drive connected, if it does then reconnect hard drive and try to boot in safe mode.

I have just realized the need to connect the 12v 8 pin connector in conjunction with the 24 pin ATX power cable.

This results in the the computer fans switching on for approximately 10 seconds and the computer restarts- this is continuous.
Again nothing displays on the motherboard.

I may have had the same problem. I had 2 corsair vengance chips, and they were denoted weird. they had 2x4GB per chip. so I had 16 GB of ram. it really screwed me up.
Try putting in some smaller ram chips if you have them.

Hope this helps :D
