Screen goes red and green then PC crashes

I recently installed a gtx 750 and it runs games well but sometimes when I turn on my PC it goes red and green on the screen and crashes then it restarts I play games like players Unknown battlegrounds
My specs are;
I5-4460
8gb ram
Gtx 750 ti
1 or 3 Tb hdd

This only started happening after recently installing the graphics card, any help would be appreciated!

  1. Try to completely uninstall the graphics drivers, then install latest drivers downloaded from Nvidia.

  11. PSU = Power Supply Unit.
    Reply to Kasper Jorgensen
  12. I think I get a maximum 250 watts

  13. That's not enough to power a GTX 750 TI.
    Min. Recommended PSU for that card is 300 or 350w.

  15. Do you think that is the problem, if I don't change my psu will my PC still work?

  16. I obviously cannot be 100% sure, but as you are running a too small PSU it seems likely to be the problem.
    Basically you cannot run that GPU with your current PSU.

  19. It will crash when it needs more power than you PSU can deliver.

  21. Okay, should I buy one or would I not be able to install it

  22. Considering you didn't know what a PSU is you should probably get someone with a little more computer knowledge to help you.

  24. Are you confident that it is the power supply, as sometimes I can still play and do other thungs

  25. Obviously i cannot be 100% sure, but as you are running a GPU out of the specs of your PSU it seems likely that is the problem. Maybe you have a friend who owns a larger PSU you can borrow to test if that solves the problem before you buy a new one.

  31. Look man, test with a larger PSU to see if that solves the problem. It's a waste of time keep guessing what else it could be when you haven't tested the most obvious possible course of the problem.
