Been using this PC for 5 years, out of nowhere when I came home the computer was running horribly slow and constantly locking up. Realized CPU usage was going from 8% to 100% almost every second, temperatures were 50c to 80c as well.

This has got to be something wrong with the CPU right? Heat damage maybe?

Any advice would be awesome, I ordered a new 4790k to test.

The stock cooler is not all bad but it is noisy.
If not overclocking, you should be ok.
Also, make certain that your case is delivering fresh air to the cooler.
If in doubt, take the case covers off and see if that is better.


50c. at idle tells me you did not install it well.

What is the system specs? What is the CPU? What are the temps underload?

Could be a Virus. There are a lot of crypto viruses running around that get your system to mine and would use a lot of CPU resources like you described. A simple sweep of Malwarebytes may show something.

Those are my specs, oh man I didn't even think of that, ill try it when I get home.

Underload my temps were going up to about 81 c, which is high but not high enough to cause those problems.

Yeah I did that as a first step, realized the heatsink is kind of loose, but I don't think 80c is high enough to completely cripple the computer.

I'm going to definitely run a malware test

If a processor approaches 100c. it will slow down or even shut off.
The fluctuation you see may be the cpu throttling sufficiently to cool down a bit, then rising to top temperatures when the throttling is removed.

What is your cpu cooler?
If it is mounted well and functioning, you should see 10-15c at idle.

CPU cooler is a stock 4 pin push in cooler.
The thing is my idle has always been around 50c
The pins don't click in all the way, they seem busted.

Think heat damage could of finally done my cpu in?

Could you also recommend some good CPU coolers that aren't a total hassle to install? I know for a lot of them you have to install a back panel behind the MB.

81C is not hot enough to damage that CPU. Above 90C for prolonged periods can damage the CPU, but you would be having system crashes and see performance loss all the time running at those temps.

50C is a high idle temp, but what are your ambient temps? You will never idle below your ambient. Plus you are using the stock cooler on the 4670k. Intel does not even provide a stock cooler on the "k" models anymore because their stock coolers are so terrible. So it would make sense to have a high idle temp on a stock cooler.

Cryorig H7 is a good $25 cooler. If you can install an Intel stock cooler, then non of the aftermarket coolers will be much more of a hassle. If you are not planning on overclocking, then don't spend more than $20 on a cooler and go for a 212 EVO.

Thanks for the recommendation, yeah these stocks are a total pain in the butt. Do you think its a possibility my CPU is just getting old and got damaged? Ive never had a problem like this, I'm going to go home and try all the fix's suggested and I already have a backup ordered on the way. Along with the cooler you recommended.

I don't know if your CPU is damaged. But what I do know, is that typically when something is not working right, it is usually something that I missed and not a hardware issue. So before I just gave up on it, I would see if I could figure out what the issue is.

The CPU is not that old. There are a lot of CPUs that are running just fine that are a lot older. If you had been running it at 90C+ temps for the past 4 years, I think you would have found out before now and your temps would not just magically drop to 80C.

----------------how to mount the stock Intel cooler--------------

The stock Intel cooler can be tricky to install.
A poor installation will result in higher cpu temperatures.
If properly mounted, you should expect temperatures at idle to be 10-15c. over ambient.

To mount the Intel stock cooler properly, place the motherboard on top of the foam or cardboard backing that was packed with the motherboard.
The stock cooler will come with paste pre applied, it looks like three grey strips.
The 4 push pins should come in the proper position for installation, that is with the pins rotated in the opposite direction of the arrow,(clockwise)
and pulled up as far as they can go.
Take the time to play with the pushpin mechanism until you know how they work.

Orient the 4 pins so that they are exactly over the motherboard holes.
If one is out of place, you will damage the pins which are delicate.
Push down on a DIAGONAL pair of pins at the same time. Then the other pair.

When you push down on the top black pins, it expands the white plastic pins to fix the cooler in place.

If you do them one at a time, you will not get the cooler on straight.
Lastly, look at the back of the motherboard to verify that all 4 pins are equally through the motherboard, and that the cooler is on firmly.
This last step must be done, which is why the motherboard should be out of the case to do the job. Or you need a case with a opening that lets you see the pins.
It is possible to mount the cooler with the motherboard mounted in the case, but you can then never be certain that the push pins are inserted properly
unless you can verify that the pins are through the motherboard and locked.

If you should need to remove the cooler, turn the pins counter clockwise to unlock them.
You will need to clean off the old paste and reapply new if you ever take the cooler off.

Thanks for the reply, yeah I'm going to go home and try some stuff out. The annoying thing is I never really power off my PC, and this problem began happening all of a sudden without a power off or crash.
