My computer has very recently started to lock up whilst I am playing games .. I have looked at the temps for the GPU and CPU and they seem fine...These lock-up's only seem to occur when the games are running (not had a lock up on a menu screen yet.)
As I said this has only started to happen over the last 4 days (Also everything else on the computer (ie. Videos, streaming, internet) works fine .. before that the system ran like a dream..

I don't want to go out buying new part's until I know Exactly what I need to replace (if I actually need to replace anything)

My system is-

MoBo - Asus M5A78-M/USB3
GFX - Msi Nvidia GeForce GTX 760
CPU - AMD FX-8350
Memory - 4Gbs DDR3
can't remember the name of my PSU but it's a 750w

Thanks in advance ...

If you've made no recent hardware changes, and your system has previously been running fine, and your PC is only freezing when gaming which will be when it is drawing a large amount of power, then I would suspect you need to replace your PSU, probably fairly quickly.

If you have a look at this list:

... which tiers PSUs by quality, you'll be less than pleased to find yours right at the bottom, in the 'replace immediately' category.

I would replace it immediately, since cheap PSUs often manage to take other components with them when they blow... Pick something from Tier 1 or 2. If it sweetens the pill, think of a good PSU as an investment - it really...

Thanks for the quick reply, ok ... my PSU is a Cit - ATX - 12v model: 750ub

and as to overclocking, both the GPU and CPU are exactly as they came out of the box ... I actually don't think I know enough about it to try :))

If it sweetens the pill, think of a good PSU as an investment - it really is the bedrock of a reliable machine, and should last you a long time, and successive builds.

As a suggestion, there's a 550W XFX that's good value at the moment

Thanks for the reply, I was thinking it may be my PSU ... forgive my ignorance here but does the 550W XFX have enough power to run my GFX,CPU and all the other stuff as I was lead to believe that I needed at least a 700w PSU for my computer components .. sorry if that sounds like I am a thicko .. :)

Again thanks for your response

No, no, not at all - getting the power right is important, and not always easy, I was just picking that because it was in my head, I don't know what your build needs

Try putting your parts together in pcpartpicker.com - it will give you a suggested minimum wattage, then add 100W or so to that in case you decided to overclock at some point, and buy a good brand

I have looked at the website you gave me and I seem to only need about 400w ... But I am not sure ... is there anyway to see how much wattage I am currently using on my PC ?

Ok so I bit the bullet and went for a tier 3 card off of that list (I have absolutely no intention of overclocking any part of my system) and I went with a Corsair CX750 Builder Series 750 Watt ATX PS/2 (I went with 750watt as I know that's enough power) I will know tomorrow if it fixes the problem ...
