So today i got a new case and i transfered everything into it no problem. i was just browsing the internet when my screen went black. my keyboard and mouse were still lit. I didnt know waht was wrong so i tried pressing the restart button the the mobo but nothing happened not even a number on the debug. I turned the psu on and off the tried to start my computer. Absolutly nothing happened not post no beeps no lights, fans, nothing. I left it alone for around 5 minutes then tried starting it and everything lit up and spun up but then it just went strait off and it went on and off again about 3 times untill it just ceised working all togeather again. I took the battery out of the motherboard and put it back in but that did not help anything. The problem is repeatable. I leave it alon for a while and it does taht weard on off thing when i try to boot it then if i try to boot it again withing 5 mins or so it will not respond at all.
