My EVGA GTX 750 was running fine, until one day I woke up in the morning, boot my PC ... after 5 minutes suddenly my PC freezes with a yellow screen. After that, I rebooted - no display on my monitor but everything is running fine inside my case. I have tried everything, even i tried the GPU in another system...same problem..I cant figure out what is wrong with my gpu?? Plz help me..

If I take out the GPU and put it back again after 4-5 hrs., suddenly display on my monitor , boot properly and then after 5 mins, same problem.

My MB-MSI B450 PRO VDH MAX, CPU-AMD Ryzen 5 3500, PSU- Gigabyte 550 Bronze are brand new. Disassembled and reassembled like 100 times.
