blender randomly crashing my laptop if i use it for an hour

I have a 3060 laptop i7 12th gen 16gb ram laptop which I've been using for the past 3 years and about about 6 months ago my blender would randomly slow down my pc after I've used it for about an hour, to a point where it would take a solid 2 minutes for me to more my cursor from one side of the screen to the other,
I looked around for a solution and heard that it could solve itself by clearing gpu cache (ctrl + win + shift + b) which does work when this issue happens, but only solves it for 2 minutes until it happens again
This has been consistently happening irrespective of what work I've been doing may it be low poly modelling, sculpting, etc and this kind of crash happens only when I'm using blender and affects other apps and ui even after I close it and goes away for a while only after I restart or clear gpu cache
I've tried basically all solutions I've heard from chatgpt and whatever I searched on youtube, I am planning to do a reboot if there's no other options left but I really wanna finish working on my blender projects without going through such a hassle.

please help a brother out with ts if any of yall have any similar experiences or a solution to this problem, its really annoying to deal with once it starts and I just want it gone
