Thought I had a bad PSU but it was fine. use my old or new one?

[sf1989]

I had a 1300w EVGA G2 Supernova gold PSU. I got it in the summer of 2012 or 2013. not 100% sure. Used to have my PC on 24/7 for a few years. But just watching videos and internet. No hardcore gaming for the most part.

I thought it was going bad since I am getting black screens in destiny 2 and shadow of war then a crash. I went to Fry's on christmas eve and got the best one they had in stock, a 750 PC power and cooling MKIII Silencer Gold rated. Still got crashes. Bought a few games like starwars battlefront 2 and need for speed payback and got close to 60 FPS on high/ultra for hours with no crashes.

So both PSUs are good most likely. Some other issue I need to figure out. Should I put the 1300w one back in my PC? Or should I just leave the 750w one in. Is 4-5 years on it enough too much? It has a 10 year warantee so I'd guess it'd get a few more years.

I have an i7 8700k I use MSI game mode on to overclock it. And a 980 gtx i use EVGA precision on. Soon to be a 1080ti FTW3.

MERGED QUESTION
Question from sf1989 : "Shadow of War and destiny 2 crashing to black screen after new hardware"

Got an i7 8700k, MSI Krait gaming mobo, and 16 gb DDR4 corsair RGB ram 2666 and a 1tb crucial SSD today and redid my PC. I installed everything again and got the 2 games i want to play downloaded. have a 980 GTX too. When first installing windows 10, it was stuck in a install loop until i unplugged the USB with the instalation media on it. Then it booted and ran fine.

But now they crash all the time. Before, I had
i5 4670
MSI z97- g45
256 samsung SSD
16 gb corsair DDR3 2400
980 GTX

Back when i had that hardware installed theyd crash to a black screen but like every 3-4 hours. Was tolerable. Didn't bother to fix it. But now shadow of war and destiny 2 crash very soon and it isnt even playable.

I have game mode (OC) on the i7, the temps gaming look alright i think. 45-55C or something in the tower in destiny 2. I have XMP enabled in the bios for the DDR4, othewise it runs at something like 2100 speed. I use EVGA precision for my 980. Have it set on 60 FPS target FPS. I get 50-60 FPS in destiny 2 on 2560x1600. Moslty 60.

When i turn off my PC via the psu and turn it on again, windows boots and says the graphics driver failed or something in the action center.

What can I do to remedy this? Also, some windows programs are going slow. When I click on links to URLS they take minutes to load.
