Hi everyone.
I am new here so I hope that I am posting on the right section of the forums.
Here is my problem, the card I have is a GTX 750 Ti from MSI which is a Twin Frozr 2gb card. I was playing a game and suddenly the screen went black. CPU crashed. I thought it was nothing but when I powered the PC on, there was no display. After a few seconds or a minute, the GPU fans will start to spin 100% (based on the noise) and my monitor would detect a display although only black. I have already tried several troubleshooting steps including testing the card on a different PC.
The computer still detects the card because if I use my onboard graphics, the device manager still see's my card but there is an error code 43. I have also tried flashing the bios to no avail. I have had the chip reflowed to no avail. Only thing I can think of based on youtube tech videos is a short component. Most of the videos and forums I went into says that the mosfets are the problem.
So, I disassembled the card and found one mosfet, using my self made continuity tester (LED lights up when circuit is complete), I placed one probe on the ground and probed on the mosfet. Here is a picture
APL1117
CP94F
is whats written on it
So one of my probes is on the ground whilst I probe the feet of the mosfet both left and right (I don't know much about electronics so please forgive me) the led lights up. Could this mosfet be the culprit? sadly I don't have a multitester as of now but will be getting one soon.
Hope someone can help.
Thanks!
