laptop - Dots and black screen while gaming
2014-07

I have a very annoying problem with my PC.
It's specifications are as follows:
- Model: ASUS N55SF Notebook
- Processor: i7 2670QM 2.20 GHz
- Graphics Card: GT 555M 2 GB
My issue is that I get black screen while gaming and dots appear that are sometimes red, sometimes green, and sometimes multiple colors. These dots are moving around on the left side of the screen. I need to shutdown the PC manually to get rid of the issue.
I've tried the following:
- Formatting the PC
- Cleaning the dust from my PC
- Changing thermal paste
I didn't have the problem for 2 weeks, but now the problem has started happening again.
Some additional info pertaining to the temperatures:
- The processor while gaming: 91°C max
- The GPU while gaming: 76°C max
- The processor under normal use: 40->50°C
- The GPU under normal use: 36->40°C
EDIT : Do you think baking the GPU is helpful to solve this problem ?

Usually things like this boil down to high temps and/or hardware failures. It might be the GPU itself, the GPU's fan, the case fan(s), or even just a borderline heat problem that is exacerbated by the room temperature.
You've cleaned the case out once and the problem went away for a couple weeks. I'd say clean it out again and see if you can get some better air flow to the GPU. Maybe the GPU fan needs replaced, maybe you have case fans that aren't working as well as they need to. Heck, you might even have a situation where the ambient room temperature is getting to high for the fans to be effective.

This is usually a defective GPU, or overclocking the GPU which accesses shaders/etc that are not working.
Basically the driver crashes so badly due to some unexpected hardware problem that the entire system crashes. If your pc is relatively new, see if your GPU still has waranty.
Try a different GPU to verify that the GPU is defective. Also try this GPU in another pc to make extra sure.

I just cleaned PC (well CPU fan only), and i turned PC on but forget to insert CPU 4 pin wire (not the first time). Unpluged PC from electiricty. I inserted it and turned on PC, then the CPU cooler started to spin like crazy. Windows loaded and cooler started to work normally but motherboard temperature was 60 C. I restarted the PC to check BIOS settings, but the screen was black, no beeps, hard disk were spinning as if there were loading windows, i tried to reset BIOS setting but no affect just black screen. DId i damaged the motherboard. I forget that i was playing minecraft on built in graphics card (20 - 30 fps, yes i know bad, but i wanted to play so much). Maybe video card is dead?? please help! Specs that I remember:
Motherboard: HP P4SD
CPU Intel Pentium 4 2.80 GHZ
Ram 1.5 GB DDR, (1 GB + 256 MB + 256 MB) - Kingston
Built-in video card: Intel (R) 82865g
Edit
I have re-seated the RAM but look what happened:

Judging by that picture, the fact you're using an integrated video adapter, and your remarks about sticks of RAM not working, I'd say you have bad RAM.
Get Memtest86+ (or another competent RAM tester) and run it against the RAM sticks, one at a time, for many hours (we do 48 hours of testing before declaring a RAM module as "passed").
This should help you identify which stick(s) are bad. If they come up clean after 48 hours on each stick, then I think you'd be at a point where you need to start swapping in known-good parts to find the culprit (RAM modules, motherboard, PSU, etc.).

When you cleaned out your PC you could've had some dust moved in critical areas, take another look at it and make sure there's no dust or anything trapped in the PCB of the motherboard, also try and locate where the integrated Graphics is, if you provide the model of your motherboard I can help further. Not putting your CPU Fan wire in could have caused the CPU to heat up but shouldn't have caused any damage since the heatsink was placed on top.
What I would suggest your do is give it another once over.
