VERY SLOW, LAGGY PC, Please Help, Out of Ideas!

[calebloperfido1245]

Okay so for the past several days my PC has become super slow. Slow as in every program is laggy and gets glitchy. I just completely refreshed my PC and reinstalled windows thinking I had a virus but the problem has not been fixed. Using Chrome or any program is a struggle. Just loading a page will take minuets even though I have great internet. Once it loads it's just laggy and prettu much unusable. 95% of the time it will be super slow and laggy. A random 5% of the time my PC runs fine. For example, this problem effects my GPU performance and will cause my FPS to fall dramatically. I ran the Kombustor 3 benchmark and got an average of 20 FPS. Five minuets later I tried it again and got an average of 330 FPS. I'm so confused!. I don't think my GPU is the problem because there are no whining fans are colors being messed up. Could it be my hard drive or CPU? I've tried many solutions but please help! I have no idea what to do now!

Have you monitored your CPU temperatures?

Have you set up perfmon to monitor your system?

The temps are fine I believe. I did notice that my CPU will dip to below 1GHz randomly. The cpu is at about 5% or below for utilization and the speed is at .75Ghz. My friend said this means my cpu is probably broken, it is about 4 years old. However before I go buy a new one, I thought I would get some second opinions.

Have you tried to run for example Bitdefender or Malwarebytes? It might just be a virus that is hard to detect and those two are good from my experience.

Yes, and did a clean refresh, no viruses. Also searched using Malwarebytes, Everything is good

Use you PC 15 mins than restart, access bios menu and go @ Pc Status or Health / monitoring tab.. Look at the Cpu temps to get accurate numbers.
If temps are ok it's probably software/registery issues, you could try Cpu parking manager V3 from coderbag (look on google) run it and set it to high performance mode

low clock speed at low utilisation is not a sign of problems.

The CPU goes in to an idle state when there is no work to do.

A problem is where you have low clock and 100% CPU.

Step 1. Hold windows key + press the R key.
Type "%temp%
Delete all the files that can be deleted.

Step 2. Do the same as nr 1 but without "%"

Step 3. Defrag your harddrive / ssd

Step 4. Download "ccleaner" and delete unnecessary files.

Step 5: delete programs that you don't use.

Step 6: Press the little arrow in the bottom right corner of your screen, right click on the icons and then "close"

Step 7: Right click the taskbar > task manager > go to the tab "auto startup" or something along those lines > disable programs that you don't need to start up when you boot your pc.


That's all i know, hope this helps!
