I've been gaming for a while now. When playing certain games this PC goes into overdrive. The fan/fans start/s to sound like a jet engine it/they get/s so busy. Also I have smelt burning when this has happened. The fuse blew on the 4 socket adapter I was using recently.

On the following thread someone said this could be due to the PSU not being strong enough to handle the load, in what it seems could be a related issue someone had, although the person who posted this question did say that blowing a fan on their PC stopped it crashing in that case: http://www.tomshardware.co.uk/answers/id-2047543/gtx-650-overheating-issue.html.

This is exactly what they said:

Your GPU isn't overheating. 70+ before it would shutdown and cause a restart. Make sure your PSU is strong enough to handle your new system at load and possibly run Memtest to check your RAM (although not BSOD'ing and just shutting down points to the PSU).

This (the PSU part) makes more sense to me than it being to do with dust etc, since it seems a more plausible explanation of why the fuse blew.

The PC has no problems except when playing certain games: i.e. TERA Rising and WoW with add-ons (I think WoW is ok as long as I don't have more than 1 add-on (Healers Have To Die)). I'm just wondering if anyone knows or can suggest what I might be able to do to be able to play these games without this problem occurring.

The PC's spec is this:

Display: NVIDIA GeForce GTX 650

8GB RAM (6 available)

Processor: AMD FX (tm) - 8120 Eight-Core Processor - 3.1 GHz, 4 Cores, 8 Logical Processors

I have read on another post that forcing vsync in the Nvidia Control Panel helped with what seems could be a similar problem, so I plan to see if that solves it, God permitting.
