I was playing LOL then the desktop bsod and when i tried to turn it on it entered a boot loop (black sreen). I forget to look at the error message but last time it bsod (2 weeks ago) it was atimak or sth like that. I suspect it's the vid card problem so I removed it and plug the screen to the onboard card. This time screen would show boot screen but reboot right after. At this stage I'm able to enter bios. I unplugged all peripherals but still the same. My suspect: video card 4870 or psu corsair hx620 History: i had this problem before with my old desktop. i chanced it and bought new mobo and i3-2120 and new ram and it solved the problem. I have been using the 4870 and psu corsair hx620 (moved from old system to new system) for about 4 years. What should I do?
