First thing I would do is un-make and then re-make all PSU power connections again and listen for the connectors to click together, all while switched off and unplugged from wall power.

Thanks thrashzone for the greeting. I will fill it up once i get home.

Hi linnemeyerhere, that's the first thing i did previously. But don't seem to sovle the issue. Just to add on, whenever i finally get it to boot up i notice my time and date will be incorrect it will stop at around afternoon time. I thought it was the CMOS battery running low as i gotten this pc 3 years back. I replace it and this issue still occur. This problem come and goes. I am able to boot and shut down successfully this morning before leaving for work.

Boot into your bios and have a good look around at the settings as well, set date and time in the bios and make sure your drive order is correct and such, save and then re-boot. If successful booting then close and re-boot several times. How stable is your house voltage? I consider my UPS battery back up as a key component to any important electronics. Many mobo's have a bios reset to factory settings, this could be a good idea then if needed modify settings from there.

When I replaced my PSU a few months ago, also a Corsair, I had a hard time getting the 24 pin cable to clip onto the motherboard. There needs to be a distinct click when you push it down. If you are not getting a click, it is not secure and can come loose when you are using it and cause the PC to shutdown. It also does not boot sometimes because it is loose. If you are having this problem, you need to order one of these and it will do the trick. Amazon.com: StarTech 8-Inch 24 Pin ATX 2.01 Power Extension Cable (ATX24POWEXT): Electronics

Hi bigmck.

I am pretty sure i push it all the way down, cause i took a torchlight to double check the connection isit ok. But still thanks i will do the connecting again espically on the 24pin cable. Thanks

I did all of the above. Reconnecting all. And all. Problem still occur. Right now i can't even on it. I really don't know what to do already
