bugcheck 124 is a bugcheck called directly from the CPU, mostly because if got a internal error.

This is most often a overclocking type bug where the CPU does not have the correct voltage at the correct clock rate.
It can also be cause by overheating of the CPU.

so, update the BIOS to a current version or reset it to defaults with no overclocking. If you have overclocking software installed, remove it.
and check to make sure your fans are working, use compressed air to blow out dust.

you can also get this with certain power fluctuations in the power system.
common if you added a new video card and you power supply is slightly under powered.

I have never used overclocking software on my PC. I have had problems with overheating but have recently blown most of the dust out with a can of compressed air; as much as I could anyway without removing parts and everything seems to be a little better. So could this be a problem with the voltage or me just not correctly cleaning my PC?. This is unrelated but when I opened my case to get in there and start cleaning I noticed a port was open that was labelled SYS_FAN with a cable that looks like it fits in that slot hanging near it. I have noticed the case fan isn't on but as this is the first time opening/owning my own pc I don't know what would happen if I plugged that in. If you could offer any insight on that it would be appreciated.

you might want to check you power supply fan. sometimes they get dust in them and run slow or stop and the power supply overheats and the voltage to the CPU/motherboard fluctuates.

If the fan cable and the pins for the fan match they may have become disconnected.
they tend to use very cheap connectors that come loose. I would connect it or look in the motherboard manual to confirm the type of fan it should be.

if it is a CPU overheating, you may find that just blowing air into your case prevents the problem. You could also install a program that monitors the CPU temps.
maybe something like http://www.cpuid.com/softwares/hwmonitor.html
someone might have a better suggestion as to the best program to use.

Thanks for your help. I checked inside my case and had a look at the PSU, it was a bit dusty and I cleaned all that out. On the side of the PSU it said "Corsair 450" assuming that "450" is the power it is giving out, is it possible it is just having difficulties powering my system. My CPU is a amd fx(tm)-8350 eight-core processor 4.00ghz while my GPU is a GTX 660.
