Computer Hangs Randomly

[Indicator34]

Hey Everyone,

Built myself a PC September 2012 and since a week or two after completion (I can't remember exactly) it has had a problem with hanging randomly.

It can happen anytime, whether I'm just using iTunes or running many programs at the same time, The screen freezes, any sound will either continue distorted or play at the same frequency and pitch looped. This can last a few seconds to a few minutes, but will eventually respond again.

I have tried many "Solutions" i have seen on the internet and have now decided to ask specifically because it is extremely annoying.

Specs:
OS: Windows 7 Ultimate 64 Bit
Motherboard: Biostar TZ68K+ ATX
CPU: Intel Core i3 2120 Dual core @3.3GHz
RAM: Kingston 8GB (2x4GB) DDR3 1600MHz HyperX Genesis Grey XMP CL9 1.65V (I'm currently running this at 1333MHz due to advice from a fellow builder who had a similar problem.)
Graphics Card: Sapphire AMD HD7750 1GB DDR5
HDD: Seagate 500GB 3.5" SATA-III 6Gb/s Barracuda 7200RPM 16MB Cache
PSU: OCZ ZS Series 650W

If any other information is required, I can provide it.

Thanks in advance

The part that speaks most to me is the RAM with the 1.65V.
The memory controller on the i3 handles 1066/1333 and you're underclocking 1600 RAM to run at 1333, not to mention that voltage is not good for the CPU.

You can get 1600 RAM with 1.5V but it will run at 1333 due to CPU limit, or just get DDR3-1333 (could always double up on it).

If it comes to it, I will get new RAM, but at the moment i cannot due as i can't afford anything.

I have checked the RAM in the Bios, it was running at 1333 but voltage was at 1.65, i have put it down to 1.5 as the datasheet i have found says it can run at that. If it hasn't hung by this time next week, i will assume that was the cause, if it does...

Well, It hung... Any other suggestions?

Honestly, just changing the voltage to me doesn't seem like the real solution, I would really try the RAM I suggested or any RAM that runs stock at 1.5V. If that's not it, I'm really not sure what could be causing it to hang.
