hi guys, i have got a problem with my computer. so i bought a new case for my computer(because i bought new vga, and it doesn't fit on my old chase) , then i moved all of the hardwares from my old case to the new one. After everything installed, when i turned my computer on , it was like on for 2 sec and then went off , and keep doing the same thing continuously. my psu is okay , because i have tried it by putting a clip to the green and black cable and all the fan worked fine. I have tried to remove my RAM , and removed my vga but the same thing still happening. i moved my hardware from the old chase to the new one on 30 august 2014 6.00pm, on the same day before i moved my hardware from the old one to the new chase, everything was okay, my computer kept on for about 4hours and i could do everything(browsing, gaming,etc) . the only thing that i haven't tried is turning the computer on without motherboard installed on the chase( so the i won't put the motherboard on the chse but i will keep connect my psu to the motherboard). and i have no more idea about what iam going to do to fix this computer. please help me guys, thanks , i would really appreciate your idea.

spec
motherboard: MSI H55MA-E43

It sounds like the motherboard is shorting out or touching the new case somehow. Be sure that the tabs that hold the motherboard up, stand off's, are in the proper place and that you are not over tightening the screws when you screw it down.

i have checked that the motherboard did not touch the case, i even tried to put my motherboard on a carpet once and on a cork, but it did not change anything. I tried to use another psu, and nothing change. i just connect my motherboard to psu and the casing power sw, and a Ram on it, but it didnt change anything as well.
