Frequent freezing on intensive games with new CPU.

Alright my specs are:
AMD Phenom II x4 965 3.4GHz
Sapphire AMD Radeon HD 7770 OC
8GB DDR3 1333MHz RAM
650W Ezcool PSU
500 + 200 GB 7200RPM Hard drive

Whenever I play intensive games such as Crysis 2 and Battlefield 3, the game will randomly completely crash. It's happened frequently and randomly and I don't know why. It'll run the games completely fine @ High presets, 1280x1024 then just crash. Does anybody know what's wrong?

If I had to guess right off the bat I'd say your PSU is failing to meet maximum loads. I had a similar thing happen on my old build and found out it was indeed my power supply. I swapped for one that was better constructed and it was all good after that.

The processor is rated up to 62°C and you've hit that. Why can't the temperature be part of the problem? I've known AMD chips to be more sensitive to temperature than Intel, and generally start to cause stability issues when run too warm. 33°C sounds a bit high for an idle temperature.

I heard the Phenoms are good overclockers somewhere. Just throwing that out there. But there shouldn't be a problem regarding temperatures. It's running at the stock clock with the stock fan.

While stock fans are usually fine under ideal conditions, I've seen my share of people, posting on Tom's about problems, that I would not consider to be running their equipment within ideal conditions. If you live in a warm climate, perhaps near 30 and above, you're going to be close to the limits of the fan that comes with most processors. Just because you're running stock for clock speed and fan, doesn't mean you won't have temperature related problems.

Whether or not a Phenom is a good over clocker isn't really relevant to your issues unless of course you're overclocking it. :) Even when overclocked, your chip is subject to the same thermal related limits. This in no way gives you better temperature tolerance.

On another note, fans and the heat sinks they blow against do get dirty and need periodic cleaning to maintain efficiency, although you mentioned your processor is new, so this is unlikely your case. It may be worth taking a side panel off of your chassis to see if you can get your temperatures down some, and if things improve when you do. Maybe even temporarily place a box fan where the side of the chassis was to increase air-flow.

The only other thoughts floating around here are related to your power supply. It would be worth swapping a different power supply in temporarily to see if you can relieve the symptoms of the problem.

When swapping out power supplies, if you attempt to run your computer for gaming purposes, I would pick a power supply with at least 36 amps on the 12 Volt rail.

You should also be able to locate the rating on your current supply to determine if it is close to it's current limit for the 12 Volt rail.

So what Power Supply would you recommend?

Yeah I think that would be a huge red flag. :lol:

That entirely depends on how much you want to spend. Something like a Corsair TX650 or a PC Power & Cooling Silencer MKIII are excellent choices around the ~$70 range.

As it's been said before, "don't just take my word for it!" Look at the reviews on power supplies before you drop your dough on one. It's worth doing a bit of homework. A few brands I would trust are Seasonic, XFX, and Corsair. Expect to spend upwards of $70 on a decent PSU. The only way you can get much below that and still produce enough power to run a mid-ranged PC is to skimp way too much on the components in the supply and / or exaggerate what the supply is capable of.

I'm British so that would be like £45-50 which is actually the price I was looking for. I can't really go as high as £60 though. So with that budget, what do you recommend?

Something like this: http://www.scan.co.uk/products/550w-psu-xfx-core-edition-p1-550s-xxb9-85-eff-80-plus-bronze-sli-crossfire-eps-12v-quiet-fan-atx

I would say, if your budget can reach 85% of the way to a proper supply, I would strongly recommend you wait and save. Never skimp on a whim, on a part you're keeping for a while, and is essential to the everyday fitness of your machine. :) I like and agree with the suggestions g-unit1111 has come up with.

Alright, I'll order the XFX Power Supply. Will I be able to overclock my CPU and my GPU with it?

I just bought and installed the XFX 550W Bronze Certified PSU. I'm still having the same problem. I'll be playing Crysis 2/Battlefield 3. It'll freeze. I'll ALT+TAB out and I'll get a notification saying that the AMD Display Drivers Crashed.
