So I had this Radeon hd6870 laying around and I tried it in this pc with this 450w psu and it worked fine for awhile then the pc died and now I get bootloops no beeps or anything, the psu is fine cuz I tried it in an lga 775 system with the gpu and I was playing games without crashes?

So i dont know what happened did the psu fry anything or whatsup?? 

There are no bent pins in the socket.

I have tried 3 different psus and different ram, 1 ram in each slot, i have resetted cmos, reseated cpu, tried different cpu. 

Spec:

 i3 2100 & i5 2500k

 H67MA-45 (B3)

 450w vp450p

 1 ssd

 8 gb ram

Yep, I forgot to type this but If I let the cmos battery be unplugged for like a few hours and I plug it back in and start the pc It starts up but then it dies randomly when Im in windows or something after awhile and then I get the same rebootcycle

What do the capacitors look like? Any bulging or leaking? 775 is pretty old for any electronics.

I had a simular problem, and when i did a fresh install of windows, everything was back to normal. With me, I was drawing too much power from the power supply decreasing the voltage of the 12V rail to 6V. This crashed windows in the middle of an update, and when I tried to restart, I kept getting a bootcycle

If you want me to see your reply, please tag me @Faisal A

The capacitors look fine I think, heres a video I got on the reboot cycle, so randomly when I let it be off for hours unplugged all 4 leds will go on and it will boot, in the bootcycle no beeps at all.
