First of all - Welcome to BC !
When you say 'crash in the middle of a little light raiding' do you mean there is a sort of click and the computer literally stops dead, no blue screen, nothing, just dead ?
If this is the case it is almost certainly thermal shutdown due to overheating either of the CPU or your graphics card. The No. 1 cause of this is accumulated dust and dirt; the No. 2 cause is failure of the thermal bond between either the CPU or the GPU and their heatsinks. Happily, the first is easier to deal with and much more common. But to make sure, download and run 'Speccy (free !) from www.piriiform.com. Run the computer for a while to let it warm up before you run Speccy.
Get hold of a can of compressed air and a small soft brush. Take the side off your computer and clean the fans, heatsink grids and anything else that has accumulated 'stuff'. Touch the frame of the case before you go into the cabinet, and use something - bit of wire, pencil, whatever - to stop the fans spinning when you blast them with air. If it is really dirty, once you have loosened off the dirt you may need to vacuum it out, but don't take the nozzle too close to the electronics. General opinion here is that this can cause static problems. Having said that, I have taken a vacuum to umpteen computers, but then, maybe I have been lucky !
If you find you need to remove any of the heatsinks to get at fans and grilles, then you will need to replace the thermal paste that forms a bond between the mating surfaces. You should be able to get this in any electronics store and it is widely available on-line - look for 'heatsink compound' or 'thermal paste'. Clean both surfaces - a soft rag and iso-propyl alcohol for choice - but get them clean, then apply a thin even film of new paste to one surface and clamp them up again.
I nearly forgot - when you take the side off your computer, fire it up just to check visually that all the fans are actually spinning !
You will probably find that cleaning will be sufficient for your needs. As a guide, if Speccy shows a temperature above 75C for either the CPU or GPU, it is getting too warm.

Chris is right, that could be the issue. But if the issue persists, and you have been getting a stop error (blue screen), I suggest you get the information off the screen. Now you might notice that the blue screen shows up too fast to even read, and then the computer shuts down. To keep the computer from automatically shutting down so you are able to get the details down, go to the Start Panel. Right click "Computer" and click "Properties". On the left, click "Advanced System Settings". A "System Properties" window will show up. Click the Advanced tab and under "Startup and Recovery", click the Settings button. On the Window that pops up, uncheck the "Automatically Restart" box under "System Failure". If you have another blue screen (if that is your problem), jot down the information and post it. I won't be able to interpret it well, but others might be able to. I hope you can successfully fix your problem though!

If your computer is just going all of a sudden 'Click' - 'Dead', this is almost certainly a thermal cut-out - the protection circuitry shutting the computer down to prevent damage from over-heating. It is NOT a good idea long term to depend on this to protect your computer, apart from the sheer annoyance when you have got to the critical stage in something and then you have to start all over again !
If you are getting 'blue screen' shutdowns, this is usually due to driver problems or software incompatibility.
Generally speaking, the heatsink and fan assembly that comes with your CPU or graphics card is sufficient for the job unless you are over-clocking so long as you keep them reasonably clean, but accumulations of dirt and dust rapidly reduce their cooling efficiency.
If you believe that you need to change the fans and/or heatsinks, your best course of action would be to raise a topic in the BC section 'System building and upgrading' quoting the make and model of your CPU, graphics card and mobo.
