CPU High MHZ

Jakesterbakester3 · Nov 30, 2017

So i just replaced my water cooler in my pc after my pc was overheating due to dust in the radiator. So after i fixed the overheating problem now when i launch my pc and do anything everything is super slow and the CPU MHZ reading on Core Temp goes up to 4329 writing this. i was wondering if i was to get a new cpu this issue would be fix. I have a i7-4790k processor. Also my max resolution when i go to change it is 1600 x 1200 when i always had it on 1920 x 1080.

You don't need to replace a cooler due to dust, you use canned air and blow it out.

I suggest you re-mount the cooler and try to use less thermal paste. Use about a bb or a small grain of rice (at most). It sounds as if you used too much.

I already replaced the cooler with a new one and it came with paste on it it was an Corsair but my quesiton is about the high MHZ doing nothing i cant even launch any games.

Get sysinternals tools. They have a tool called process explorer which can give you granular insight in to what is running and what is taking resources.

I just installed it now. Nothing is taking massive amounts of resources. Im using Cool Temps and its showing the MHZ hitting 4200 doing nothing.

You can run malwarebytes anti-malware.
But something is taking the CPU cycles and that will show you, even if it is hidden or by virus.
Look again, or format and re-install.

Don't know. But it is a good sign that your OS is messed up.

how would i go about fixing the OS then?

You can try a repair install. This leaves every program in place. THis sometimes leaves problems and viruses behind.
Or you can backup your personal files and format the disk and do clean install. This is best.
