Games/Performance of my laptop suddenly gone slow

[clayieee]

I got this MSI FX420 for almost 3 years now, it used to be a little beast for me giving me super acceptable performance, new games at that year running at acceptable framerates but there's something I don't know happened, I went out the house while my siblings watch a movie on this laptop hooked up on an HDMI, when I came back and play some dota on it, everytime I run the game it shuts down, I cleaned the laptop and have it sit on top of a notebook cooler, the problem is intermittent, sometimes it shutsdown, sometime nope. But one thing I noticed is that my laptops game framerate dropped significantly that it makes me cry, also my cpu rating of 6.something went down to it's lowest 4.something but I reinstalled windows it went up to 5.3 now. There's no bottlenecking since it has 8gb of ram.

I included a snapshot of temps

Snapshot

also strange my GPU isn't showing any temps.

It's pretty shameful in my part, I'm an IT guy but I couldn't figure out the problem.

Hi,

Please do try these steps that might help to solve that issue.
- Uninstall the graphics card driver from Device Manager and in Programs and Features as well since it should have something related to NVIDIA in there as well.
- Once uninstalled download and install the latest driver from NVIDIA support site.
- Here's the link: AMD - http/support.amd.com/en-us/download
- Use the Auto Detect feature so they could give you the latest and accurate driver for your graphics card.
- Lastly reboot it once the latest driver has been installed.
