It's a 2012 model ASUS K45VM with the GPU 630M. Here's the problems:
>idle GPU clock is stuck at 660mhz
>playing games downclocks it to 270mhz and gets stuck there
>GPU-Z says it's "limited by GPU utilization" when I'm trying to play and it's stuck at 270mhz (what this means?)
>not a heat issue
Things I've tried/tested:
>playing without the battery, laptop turns off when GPU starts functioning
>Integrated graphics functions normally while playing even without the battery
>clean install on drivers, tried other versions, none helped
>changed performance settings, none helped
I thought it was insufficient power supply, but the integrated graphics can run fine with a steady voltage.
Also, since this started happening, Windows been asking to activate (I already did that one year ago) and I can't open my anti virus for some reason. What are the chances of this being a malware problem?
To elaborate, it's not overheating - the downclocking issue begins before it can even get to its usual temps (70c or so before this problem started). I've cleaned it two months ago so there's no dust clogging the air vents.
I'm wondering if it's some malware eating my resources on the background because hardware seems fine.

You thought right.

Course it can. This is because Intel fabs at about a quarter of the feature size on Nvidia, with a corresponding reduction in power draw.
"Idle GPU clock" is wrong: the chip is actually fully off, and you're just seeing the speed it's rated to.
Your power supply is busted, and it's not delivering the power it's telling the laptop it's capable of.
Test it with a new brick first, and hope it's not the VRs on the laptop.
