Pc rebooting when playing games

[Pieforlife]

So I recently put a gtx 1650 into my old pre built office computer and I tested it out with csgo and seemed to be find I was a bit worried because it got to 80 degrees C (later googling 80 is noraml)so i decided to replace the thermal paste, I did a pea size and tried to put back the stock intel cooler but It was really difficult after 40 minutes of this I could only get 3 out of the 4 twist things in and when i went to boot up csgo It got up to 80 degrees and rebooted tried to reset it and do a bunch of other stuff but couldnt play csgo, its at 60 degrees when using the pc normally.

I think I might need to clean out the cooler and add more fans onto the case but I dont know.w

Doesn't sound like your cooler is mounted properly. You might have also snagged something while messing with the cooler. Remount your cooler properly (patiently) and make sure all other connections (such as your GPU) is mounted properly too.

What power supply, CPU, and RAM do you have?

@quackwich The cooler doesnt mount back on ive tried for ages

How old is the PSU? 

And just to let you know i think that the i5-2400 is a bottleneck for the gtx 1650 because its performance and your games may run slower because of the cpu.

For the necessary heat transfer to occur between the CPU and the heatsink on the cooler, there must be direct contact at even a microscopic level. That's the whole reason thermal paste exists. Even the microscopic grooves on the cooler plate caused by machining are enough to affect the heat transfer: thermal paste serves to fill these in. Most chips are designed with something like 50 lbs of pressure tolerance, just so the cooler can be tightened down really hard. In short, this is not a "good enough" thing. That one retention screw not being tightened is enough to mess everything up.

 

If you can't get it tightened, you may have to just go get another cooler, but either way, you're going to need a 100% secure fitting.
