Since we built it my brother's computer has been experiencing periodic crashes, ranging in frequency as we tried various solutions and currently occurring about once every couple of hours.
To start with we figured it might be a memory issue so we checked the RAM was properly seated and then ran the Windows memory diagonstic tool, which didn't discover any problems. We also ran chkdsk which didn't come up with any problems either.
After that we tried updating every driver we could find out of date, most of which I did and which my brother claims he's finished by himself, which seemed to help (it did used to crash about once every 20 minutes) but hasn't solved the problem completely.
All of the installed components are detected and seem to be running correctly, the computer's core temperature doesn't seem to be unusually high (it was for a while after reseating the RAM but that was because we forgot to reapply the thermal paste, that's sorted now!)
As a point of interest, none of the drivers from nvidia's website ever seemed to work correctly, it would give a "7zip unpacking error" every time it tried to run which the nvidia website claims is due to a corrupted install file, but no download on his computer or mine would produce any other result. Eventually we managed to update it through Windows Update but I'm not quite sure how reliable that is.
I'm going to just try doing a clean reinstall of Windows tomorrow as I have a feeling it might just have not worked correctly the first time but I was wondering before I do that if anyone has any other ideas.
The build he is running is as follows:
Windows 7
Motherboard: Asus P8Z77-V LK S1155 Intel Z77
CPU: Intel Core i5-3570K 3.40GHz
RAM: G.Skill Sniper 8GB (2x4GB)
Graphics: Gigabyte GeForce GTX 670 Windforce 3X
PSU: Corsair TX550M 550W
Heatsink: Noctua NH-U12P-SE2
I have four BSOD crash reports you can look at too, as those are probably going to be more helpful than my rambling.
The first one is probably the most relevant as it came when we were running the Driver Verifier, but I personally couldn't make much sense of it.
The other three are slightly older.

Running the System File Checker returned a whole load of missing or corrupted files, so I'm going to guess I've isolated the problem to a bad Windows installation.
Only problem now is that when I try and run a repair from his disk it gives me an error code 0x80070241 and a clean install returns 0x80070570.
I'm going to download a fresh ISO today but if anyone has any better ideas I would love to hear them, I'm really not all that tech savvy.
