So my computer (i7 2600k,Gtx580,asus P8Z68-V/GEN3,DDR3 1333MHz) has been working fine for about 2 years.

how ever about a week ago my computer started ''lagging'' like hell while i was on windows.(no idea what went wrong(computer on for 30mins so not overheated and i have good coolers and no overclocks)

well i turned my computer off and it did'nt boot again. not even to bios
then i checked my GPU on another computer and it is working.
after that i noticed that the ram error light was light. well u i tested 8 different RAM:s on that computer the problem did not go away. (all ddr3 1333MHz)
The computer started restarting every time i powered it.It allways restarted (about 10 secs from power on) once and then just powered up like normally,but still no Boot/BIOS
problem is not with PSU it's fine and the board is powered and all the fans are powered.

Well i tought it was my MOBO for sure and i send it to the store were i bought it. (3 year guaraty on all my parts)
well they tested it and told me it was fine. (donno how they tested but they told me it wen't to BIOS and they installed latest BIOS)(so they might be wrong if diffucult problem)
well i tested to install everything again and the problem is still the same.
i rly don't have idea what it could be.
if it would be the CPU the CPU error light would probs be light! and the computer should even boot without GPU since i7 2600k has one build into it. (the working 580 still in PCI E-slot)
i have 3 drives in thet computer 1 SSD (128Gb) and 2 1 TB HDD:s and even if those would have failed the computer should still go to BIOS. Right?


Well i am asking for you help and opinions. Every single one of those would be appreciated! and ty for your help! (English is not my primary language so if there are typos i tried my best :D)
