After replacing my faulty GTX 660 with a GTX 750i (budget issues, dont ask) it was all running smoothly, until the last few days. Seemingly at random my screen will go black with a "cable not connected" notification on my monitor before restarting itself. My mouse and keyboard then stop working for moments.

I've checked my CPU and re applied thermal paste. Sorted out drivers and reinstalled clean ones for most stuff.

At this point it seems more likely to be a PSU issue but I really don't know. I bought a cheaper version that I was told would break just outside of warranty. (Its a week outside of it now but i cant find the order anyway)

Maybe more noteworthy is that it seems to work for several hours before going through its reboot and if i fully turn it off for a while (read 40 mins - 1 hour) it then works for hours again before rebooting. Yet if i try to reuse it after it reboots it will reboot again much easier than before, when web browsing for example.

So idk, maybe its a memory dump issue, maybe its this pos PSU that I have, but if anyone has idea please lmk.

Have you used something like speccy to check temperatures and voltages?

Hi Fruit Bat,

Yeah I've had a look. Everything is within a small % voltage wise and temperatures are not excessive. GPU goes up to 60C when strained in game but when running tests nothing is out of the ordinary when it reboots.

Gonna try a BIOS update soon but have to buy a new USB. I'm tearing my hair out.
