I upgraded my PC recently, changing my Graphics card from a NVIDIA GTX 1050TI to a MSI XT 6650; to complete this gpu installation I reset my PC and after that this problem started to happen: it consists of my computer simply going into a black screen at random times while I'm using it, my monitor goes black like the PC shutted down but the tower and all my hardware inside remains on and running, like the monitor never even went black at all. It happened about 10 seconds after I turn my computer on and some apps start opening, when trying to open a game and mid-way when I'm playing a game... Whenever that happens, I press my power button from the tower for 5 seconds so my computer completely shuts off; and yes, I have tried to wait to see if anything in the monitor shows up back again after some time but nothing. I have even reseted my PC because I thought it was some game optimization in regedit I done or even overclocking but nothing seems to work. I also tried to check Event Viewer but it just says: "Event ID 41 - The system has rebooted without cleanly shutting down first."
I then downloaded OCCT to run some tests and check what component was making the computer to "shut off". I first ran the power stability test and the screen went black instantly after i clicked the start button. After that I was 99% sure it was the PSU, then I went ahead and bought a completely new one to test out and see (Gigabyte UD750GM) and tested again, the test ran for about 5 seconds and the screen went black again. After that I went ahead and tested different components, I ran the GPU test first and everything worked fine, I ran the memory test after that and everything worked fine, but when I ran the CPU test, the computer's screen went black. So does that mean the problem is the CPU? And if it is, how would I fix it if there is a fix?
If there is anything I missed please inform me so I can reply.
