Windows 7 - Intel Video Card?Driver? Strange Problem

Well, it's not a problem (now). I'm playing old games and i got lags in places, where are many of 3D models and I'm having white spots/dots on them. Here's the pic:

Do I need to reinstall my Windows? Do i need to change my graphics card? Please, help me.

P.S. I didn't clean my PC engine about for years (from dust), it could be a problem?

P.S. 2

My System Specs:

Processor: Intel (R) Core(TM) i3 CPU 2.27 Ghz.
Graphics: Intel HD Graphics 1302 MB.
RAM: 4,00 GB.
OS: Windows 7 Professional.
DirectX: 10,0.

If you haven't cleaned your PC for a while, it could have dust build-up causing it to overheat, hence the white dot artefacts. It could also just be poor models in the game. Its hard to say at this point.

Download Speccy here Speccy - System Information - Free Download and see what temperature your graphics card is running at, and report back here with that.

A little clean is never too bad, at least every 6 month it should be done with air duster and humid swab for the fan

Thanks for help, just, only two problem i have, it's: Laptop - i'm not familiar with that and Mum (), the laptop was good thing for us, so she would be wery angry if she will know that i crashed it... LOL

Ok, thanks, i downloaded this tool, but i didn't find graphics temperature, i finded only CPU and Hard Disk temp's, here's Graphics Card and CPU information:

OK. Your on-board card doesn't have a temperature sensor. At this point, you could try two things:

1. On your game, turn down the graphics quality, and see if those white specks appear again.
2. Buy a can of compressed air, and together with a vacumn cleaner (use it gently), try and blow/suck out any accumulated dust.

Lets see if that helps.

I tried to change color depth, resulution, texture detail, but I still saw that white spots.

Try to see if there's a way to lift the keyboard gently by pulled it to you, the fan is just under. Otherwise unplug the laptop, remove the baterry & unscrew the small plastic part under the laptop (battery, ram memory, hard drive) to blow away the dust with a can air-duster and a soft brush + vacumn, set to very low energy ( becareful of statics)

Okay, thanks, will try...

Considering that it actually integrated into the CPU, if anything it will be running at the same temps as the CPU.

Ok, guys, now i think i understand whole situation.

I was opened my laptop down part yearsterday and i saw some dusts at cooler (i didn't know, what cools that cooler, that was at side of my laptop). I didn't watch, what was under my keyboard, because i didn't know how to open that.

Anyways, i was noticed that when i running the game, my CPU reaches a big temperature 60 - 65 C (Speecy helped me, thank you Golden), the biggest was, WOW, that was 78 C!!! I was scared, when i tried to record a video, how i playing the game and at one time watching at my CPU properties, I thinked that my PC will blow!
So, today I used Google to search "What does hot CPU for PC". So, i finded one information, about, how person opens a couple of browsers and gets hot processor. In that page, where i readed that, i finded a good program "SpeedFan", i downloaded that and I saw how works my CPU cooler RPM in percents. Lol, that was 12 - 30 % only.

SO, i realised about that my CPU cooler has stopped working, because it's full of dusts. When, I running the game CPU gets hot, CPU fan doesn't destroy a high temperature, so my processor gets hot and i having small spots and lags in game.

It could be right?
