Why am I having random FPS drops every couple of seconds?

So basically I've had my laptop for over a year and a half and I've kept all drivers up-to-date but on every game I play(Dota 2, World of Tanks, and even mine craft)I will be getting good fps like 60 maybe even 80-100 but it drops down to like 5-10 fps really fast and then back up and then it keeps doing this over and over again. I thought maybe it could be my GPU temperature or maybe my fan not turning fast enough and when I go into the bios everything is locked so I can't change anything.

My laptop: Acer Aspire V3-771G
CPU- i5-2450m 2.50GHz
GPU- GT630M 2GB
RAM- 8GB Dual-Channel DDR3 @ 665MHz
STORAGE- 1TB Seagate
AUDIO- Realtek High Definition Audio

sounds like a driver issue rather than throttling. Can you remember the last time it was stable and what driver version you were using?

It was never really that stable but there has only been a couple driver updates since and it really hasn't made a difference.

Yea, nvidia has released multiple drivers since like I said but none of them work...Maybe they'll fix it, but just so you know...I checked my motherboard and cpu and gpu and they were very hot...like 90 degrees celsius hot. But im on a flat surface desk. So I really don't know what to do.

It's almost definitely a heat related issue.

How I fixed it when I used a laptop: Try placing your laptop on top of a book (if you have a fan intake at the bottom) and allowing it to hang over the edge. This will allow the fan to get good airflow.

If that doesn't work you should take your laptop apart and clean out the fan(s) inside, and remove any dust. As dust in any machine is a very bad idea, as it stops heat from escaping, and will lead to escalated temperatures like yours.

If you don't feel comfortable taking it apart yourself, then you could send it to a repair shop, or even just spray a can of compressed air, inside the fan grills/vents to try and push any dust away from the entrance. The reason I suggest taking it apart is because just using air, will push the dust all over the inside of your laptop, and will only temporarily fix the problem, if at all.

90 degrees, is never good news either. A lot of laptops are actually programmed to shut off at that temperature, to avoid permanently damaging important components. Your CPU's max temperature is 100 °C, so is nearing a dangerous point.

Good luck.

I just blew some compressed air into it and its down to 40-50 Celsius...Like you said though I still might need to take it apart.
