Asrock H77 pro4/MVP Intel i5 3570 2* 4gb DDR3 corsair vengeance 1600mhz ram GeForce 550ti superclocked 500gb hard drive with win7 64bit OS installed I have connected the 12v 8 pin connector in conjunction with the 24 pin ATX power cable along with the Hard drive, CPU, cooler and RAM. The result is the the computer fans switching on for approximately 10 seconds and then computer restarts - this is continuous until i forcefully shut the computer down. nothing is displayed on the monitor.

It might be that you should firstly use a supported CPU for flashing the BIOS and then use the i5-3570.

Is there an alternative that i could try? alexoiu a c 368 V Motherboard November 10, 2012 10:41:49 PM I can't see if the BIOS chip is on socket or not. If on socket, you can order one and easily replace it. If not, a local shop might help. mrbilalahmed November 11, 2012 3:58:29 PM I have just noticed that there are a few slightly bent pins where the CPU would be placed. Does anyone know if this could be the reason why the power is cutting out when i switch the system on? Thanks in advance zomow November 11, 2012 4:05:50 PM Yes, bent pins will prevent computer from turning on completely and being function. muhfq November 12, 2012 1:13:48 AM I was thinking for some cable short etc… something short… please take a close look.. or change the PW Can't find your answer ?
