Overheating without Solution

What's up folks? I've been having a uncommon overheating problem for the last few months and it's driving me insane. I searched on the internet and at the Forum here, but not one similar problem. So, i thought that someone here could help me. Lets begin:

My basic specifications are:

CPU: Core i7-2630.QM
GPU: GeForce GT 540M 2gB
RAB: 1x 2gB DDR3 + 1x 4gB DDR3 (6gB)


I rarely used to play games on it, so i can't really tell how old this problem is, but the computer has about 18 months now. The problem is simple: it is madly overheating on the past few months. It all started when i installed Skyrim on my computer. My computer automatically detected the video settings to maximum and i had no trouble playing it at all. Than, one day, after almost 2 weeks playing the game, it begun to happen: that horrible screenfreeze with a very very annoying sound buzz. Trapped in that forever! There was no solution to that but to manually turn the PC off and on again.

At first, i saw no problem at all. Tought it was from the game itself and kept playing it for a few weeks. Once it was over, i started to play another games and begun to experiment the same situations on them, i tried Borderlands, Mass Effect 2 and Mirror's Edge, but in all them the problem kept on. I started to look out for solutions and found out that my computer was maybe overheating. I than installed SpeedFan to know my exact temperatures. I found out that with an idle computer my CPU and GPU were at 50°C. While playing a game i got over 80°C ~ 85°C on a few minutes, and than took like 50 to 60 minutes to raise up till 95°C.

My games were not simply crashing and freezing, i also got like fifteen BSOD's (Blue Screen of Death), so i was really worried. I than installed CPU ID Hardware Monitor since it is better than SpeedFan. More precise and give more information (like the max, min and actual temperatures and voltages).

The first solution that came to me was cleaning the computer. Maybe dust was clogging my vents. Since i had no canned air, i opened and cleaned it manually. I'm sure i made no mistakes since i'm experient on disassembling and assembling computers. I cleaned the vents with a soft-non-static brush, also cleaned my fan with some cotton. When i finished my computer was only 2°C cooler. So it wasn't that the problem at all.

The second solution that came to me was checking the fan. Maybe it was not working properly anymore. So i tested it a lot. With gaming, videos and everything i could. It is working properly. But when i'm gaming, it seems to always run at full speed. The only clue i had with this was that my computer was hot, and i already knew that.

The third solution came to me when i had another BSOD. After reading some posts here at the forum, i thought that maybe i had a driver issue. So i begun to reinstall every single driver on my computer, and tested a LOT of versions for each one. I installed the three last versions of my GPU's driver, also the three last versions of my sound drivers. Also tried to update my serial-ATA drivers, USB drivers, and even updated the BIOS. Twice. It is important to say that after EACH update, i tested and the overheating continues. At the end of that, i had my computer all updated, but still hot like a frying pan.

The fourth solution was given to me by a member of the Forum. I was about to destroy my computer when i read about memtest86+ and testing my RAM. So, i didn't had much luck with memtest86+, but he said that i could use Windows Memory Diagnostic. So i did. More than once. And no problem was detected at all.

The fifth solution had already crossed my mind. But to replace the thermal compuond wasn't like the first option, so i put it aside for a while. I read here on the Forum that a guy was with a similar overhating problem, and when he formatted the computer, it was alright. Maybe because there was a virus i don't know. So i done it. Twice. After i fully-installed the drivers and everything else i tested again. My temperatures was still the same. Both during gameplay and idle situations.

The sixth solution seemed obvious, but since it's not like a "first option" i waited unti all the "software" solutions don't work until i would do this one. I bought bran-new thermal paste. Opened my computer, took the heatsink and i saw that both my GPU and CPU were dry. The thermal paste seemed to be dry for months. I cleaned both very carefully and when they were shining again i applied the new thermal paste. Since i had no experience on that, i looked a few tutorials first. I applied just a little bit and scaterred very well. After that, i reassembled my computer and when turn it on... Surprise! It got even hotter! My idle temperatures jumped from 50°C to 57°C~62°C and the gaming temperature that took like 1 hour to reach 95°C was now reaching it in less than 5 minutes! Awesome right? I thought that maybe i had applied too little thermal compound. So i opened it again, cleaned again and done it again, with a little more paste this time. Nothing that would isolate instead of helping. And when i turned my computer on... nothing. Just kept with this awesomely high temperatures.


In compensation my computer now is not only freezing and buzzing, but also, restarting sometimes.
This is it. I have no other clue to the next solution... i'm hopeless now. And i can't seem to find any other solution. Also, i'm getting bored cause i can't play. Don't want to put my computer on risk. Even more.

So, i will calmly ask: PLEASE, HELP MEEE... (my voice fades out like i'm falling into a well).
