Hi
I recently bought a samsung 840 evo 120GB. I installed it in my laptop (acer aspire 5750G). Everything was working nice and dandy, I also ordered a hdd bay to put my old hdd in. While i was waiting for the hdd bay i used a 2.5 inch enclosure with usb 3.0, and once again everything was working just fine. I had it running like this for almost two weeks without any problems. Yesterday the hdd bay finally arrived and i installed it with the old hdd and downloaded the latest drivers, but today when i was playing Titanfall the computer shutdown in midgame, I thought the files may be corrupt so I re downloaded Titanfall, but this time I put it on the ssd. And the same thing happened.
I think it may be that my computer pulls to much power and it just shuts down before anything breaks.
Is that possible?
Btw here is the link for the Hdd bay

The Tjunction for your processor is 100 C, it's shutting down because your processor is overheating. Are you blocking any exhaust ports? Do you notice the fan is really loud? If not the fan may be broken. That means service replacement.
Thermal shutdowns cause alot of data corruption because alot of data that was on cache gets lost. You likely have corrupt data at best. Worse is if the motherboard is fried. Don't put in the SSD because your risk damaging it with the heat. Clean the laptops exhaust ports for dust and make sure not to block them. Check to see if the fans running (just listen for it, it should be noticeable at those temps). If it still overheats get it serviced.

As always, you can always try a clean restore using factory...

Is there anything in Event viewer? Is it listed as unexpected shutdown or just total crash (events just stop at a certain point)? It should bluescreen if it's a software exception. Try recreating the scenario and monitor CPU temps. Coretemp, HWinfo and Speedfan all support logging. Speedfan lets you control fan speeds as well(though maybe not on specific laptops). Acer laptops have overheated on me before.

Yeah I did what you said and used hwinfo to monitor. I had the window open while i was gaming so i could check temps, and right before it shutdown i saw it hit 99c :p.
I tried putting the ssd in the hdd bay, but my bios would not recognize it. It only recognized the hdd in the old bay so it would not boot. When i tried to boot it said could not find boot file.

Since I recently installed the ssd I am running a clean version of windows that is now nearly a month old, so i don't think it would help doing an os reset. And my ssd is so far away from the cpu that it stays around 40-50c and i know that won't harm it in any way.
Today I screwed out the motherboard, I saw that the fan was filled with dust. So I dragged the motherboard out in the garage and cleaned it with compressed air. After I had screwed the motherboard all in, I flashed to a new bios(modded) so i could get the option of fan control. I set the thermal limit for 100% fan speed at 50c, but it seems like this doesn't work because a minute ago i checked and it seemed like it was barely running. And as i'm writing i felt like checking if the fan was spinning alright, but no it's not spinning at all. Still when i am looking at hwmonitor the temps haven't changed the last 5 minutes despite the fan is not running. Btw now the hottest core is 53c and the coldest is 49c.
I'm thinking i may just go extreme and rip out that crappy fan and just make a bigger intake hole and strap a 120mm fan in there, it may work if i take my time to do it right.
I haven't tried gaming yet, but i will do that right now and tune back with the results.
And do you have any idea why the fan is not spinning?

For some reason cleaning the heat sink and turning up the fan didn't change anything when it came to the temps in titanfall. Mid game the cpu entered the 100c range and therefore turned itself off. So I decided to do what i said i might do my last post, go bat shit crazy with the cooling!!!!!!!

I found a couple of fans i had laying around just collecting dust, cut a bigger hole around the heat sink area and cut a hole right above the gpu. Made some screw holes for the fans and screwed them in. And soldered the fan both of the fans to a single usb plug, and just plugged it in. Here is the final product:

I have a feeling acer decided that people didn't want loud fans. Are you sure all the multipliers and vcores are at defaults? There are cooling pads available that may help a little thought their effects are persistently argued in another version of the browser wars.
Also, did you check that the thermal paste is properly applied and that the heatsink is not damaged? The thermal paste is very important here. There are plenty of guides on toms about that, choose a method you like.
Have you considered installing a DIY liquid cooling system? Bit extreme but hey, might be fun.
