Computer shuts down whenever some component reaches 50 degrees (Celsius)

So, I can browse and surf and all because my graphics card is in low use at those times, but if I play a game like ArmA 2 or Gmod for a long time and it heats up, it'll reach 50 degrees celsius easily and the computer shuts down without warning.

My case:
(Not my actual one)

The case is a cheapy 50 dollars but it has a liquid cooler for the CPU and a big fan on the top side and back.

Is there any help available to either supercool or raise the failsafe? What is the recommended failsafe temperature for something like this?

For a graphics card, I'd say about 90C maximum. I think you can change the failsafe in the BIOS

Alright, I'm not too literate with BIOS, is there a place I could find some information on setting failsafes?

[djjkxbox360]

Sorry, you can access the BIOS by repeatedly pressing a certain key when your computer first starts up. To find out which key to press, check here [url]http://pcsupport.about.com/od/fixtheproblem/a/biosaccess_pc.htm[/url]
It differs depending on manufacturer

It's F8, but I just don't know how the BIOS works on this machine, also, the failsafe is actually around 90C already, which is good but I trip it too often for reason.

Oh, have you monitored the temperature whilst playing?

Open your case and remove any and all dust from the heatsinks and fans.

Water cooling doesnt cool the rest of the board (fsb, RAM, Power regulators etc.) they might be overheating.

I'm aware of that but I need to know cooling solutions that are external and are cheaply available.
