[SOLVED] PC Slowing down + Crashing on launching of any game.

[the.boss556677]

This has been occuring for 2 weeks , I did nothing new to the hardware its been good for over 6 months now.
PC Specs:
I5-2400
GTX 1050
8 GB RAM DDR3
512 HDD
PSU is 300W

What is happening is PC is starting to slow down , and whenever I launch any game that has any graphics at all PC Either Shutdowns and restarts on its own , The screen goes to a funky color (From Green to Purple and all inbetween) or its a BSOD with no specified error.

What I did to try to fix this :
DDU uninstalled drivers and reinstalled Multiple different ones , old and new
Took GPU and RAM out and put them in again
Did Malwarebytes scan , Defragmented all drives and a windows memory check , to no avail.
Did both SFC/Scannow and DISM scans , no result.
Tried underclocking GPU , nope.
Chkdsk all drives
Monitored all usages and tempratures of RAM , GPU and CPU , Temps are at 40-60 C Max , Usages are about 50% and 3 GB RAM

This Problem happens with ALL GAMES THAT EVER EXISTED , Overwatch , Dark souls 3 , even games from 2010
Mind you , Those games used to work perfectly with hundreds of FPS , now sometimes they work with a lot of stutters and most of the time they just crash the PC.

Also they dont exactly crash on start up , they crash whenever I try to enter the game and play it meaning:
In the game starting menu , it works fine , but in dark souls 3 if I press (Continue) and it tries to load me in , boom , crash
In overwatch since There is a character in the main menu it crashes whenever that character tries to load.

Please help me , Im tired of this because this problem is really annoying. I cant play anything

From the looks of it, I'd say its either an old failing PSU of unknown branding or the graphics card is dying. If I were a betting man I'd say it is the former rather than the latter. For a test go into the windows power plan and make the max CPU speed 60-70% instead of 100%. For the GPU use MSI afterburner to set the power limit significantly below 100%. After that try to load a game and see if it does the same thing. If it does I would suspect the Card dying a little more but the PSU is still the most likely culprit.

The Card is pretty new , I got it 7 months ago and I was able to be playing everything completely fine , I will try your solution and inform you.
I dont think its the card and I sure as hell hope not that its the problem , This cost me an arm and a leg ;(

Wow , You were right , I limited the power and game instantly launched.....
Dude you a saint..
There is no way or a fix around for my PSU tho , right? I need to get a new one?

I would change back the CPU speed to 100% and slowly increase the GPU power limit closer and closer to 100% until it has the same issues and then leave it at just below that. Or get a new PSU.
