Computer freeze problems

[Maarsch]

Hello TH,

I built my own computer a two months ago. Had some issues at first which were resolved by sending back my GPU and getting a new one.

Now I have freezes.
Screen freezes, no sound and no response.

I'm running
i5-3570
Asus Z77 Pro3 (1.60 BIOS)
8 Gb Corsair DDR3-1600
2048 MB Gigabyte Radeon HD 7870 OC (12.11 Catalyst)
120GB OCZ Agility 3 running Windows 7 64-bit
2 TB Seagate HDD
Thermaltake M550W 80 plus PSU
I haven't OCed anything yet.

It's frozen so far while playing SC2 and twice while watching twitch.tv on Firefox. And it's done so in the last 4-5 days. Nothing new consciously installed (although Adobe/window updates may have occurred).

I say no response because any amount of Ctrl-alt-del won't get it to reboot the machine.
And I specified no sound because you also have those freezes where the sound gets stuck in a loop, this is not the case.
Virus-check came up empty.

Any help diagnosing/solving this would be appreciated.

Couple of thoughts:
Update BIOS to V. 1616 or 1708

Download and run Memtest86 and check you RAM

Finally got around to running that program.
Built my own system, get sent to Asia for 2 months, have to rely on old laptop. Excellent.

Anyway, I have a SHITTON of memory errors. About 23 up to test 8 and then I stopped it at 500k errors while running test 9.

Odd thing was that they were all (except 1) on addresses between 8 and 9 gig.
I only have 8 gig. . . .
