Problems with my homebuilt freezing

Hey guys, I just built a computer and I'm having problems with it freezing at random. I'm using Vista 64bit here are some of the spec I got from CPU-Z

CPU Arch : 1 CPU - 4 Cores - 4 Threads
CPU PSN : Intel Core2 Quad CPU Q9550 @ 2.83GHz
CPU EXT : MMX SSE SSE2 SSE3 SSSE3 SSE4.1 EM64T
CPUID : 6.7.7 / Extended : 6.17
CPU Cache : L1 : 4 x 32 / 4 x 32 KB - L2 : 2 x 6144 KB
Core : Yorkfield (45 nm) / Stepping : C1
Freq : 2003.88 MHz (333.98 * 6)
MB Brand : Asus
MB Model : P5Q-E
NB : Intel P45/P43 rev A3
SB : Intel 82801JR (ICH10R) rev 00
GPU Type : ATI Radeon HD 3800 Series
GPU Clocks : Core 300 MHz / RAM 1126 MHz
DirectX Version : 10.0
RAM : 4096 MB DDR2 Dual Channel
RAM Speed : 400.8 MHz (5:6) @ 5-5-5-18
Slot 1 : 2048MB (6400)
Slot 1 Manufacturer : OCZ
Slot 2 : 2048MB (6400)
Slot 2 Manufacturer : OCZ

I've tried swapping out each peace of hardware separately, and nothing has helped so far. I know it's not an overheating problem, my CPU temp never even reaches 30c, and system temp has never gone above 35c. I don't get anything in the system error log before a crash, I'm running out of idea's any help would be greatly appreciated.

Thanks,
Scott

Do you have a good PSU? How do you keep your CPU and system that cool?

Did you manually set your timings and voltages? OCZ ram tends to use higher voltages than normal.

Yes, I have a good PSU I've tested the voltages manually, my VCore voltage is at about 1.33, +3.3 is at 3.30, +12 is at 12.17, +5 is at 5.o4V. I did manually set my RAM voltages to 2.2V I haven't messed with the timing yet. What should I change the timing to?

My systems probably that cool because I'm not using it correctly :p 
I have a lot of big fans too, I'm using an Antec nine hundred

I can't tell you as you didn't provide the part number. It should be indicated on the modules, e.g., 5-5-5-18.

OK, I just checked it out, I'm set to 5-5-5-18 which is what it's supposed to be.
I'm using OCZ2G8004GK

Why did you set the voltage to 2.2V instead of 2.0V? Were they unstable at 2.0V? I would expect the modules to be in slots 1 and 3 for dual channel operation (as required for the similar P5Q Deluxe). What does CPU-Z Memory tab indicate? Single or Dual channel?

You CPU voltages are fine, but it doesn't necessarily mean that it's good.
