When I game (WoW, BF BC2, CoD MW2, L4D2, etc), my computer crashes. It could take 10min into it, or an hour. It doesn't give a BSOD, which is weird (because I have the setting set to not restart on system failure), but it sometimes goes black, or a screen with white lines horizontally. I watch my temps, volts, and fan speeds and nothing is out of the ordinary. Everything is on auto/default, as in i'm NOT overclocking, though i have seen defaults be set wrong by the mobo. Recently built a new rig:

Thermaltake W0106RU 700W

Western Digital Caviar Black WD1001FALS 1TB 7200 RPM 32MB Cache SATA 3.0Gbhttp://www.newegg.com/Product/Product.aspx?Item=N82E16822136284

G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) F3-12800CL9D-4GBRL


I've got a fresh Win7 Professional 64bit on the SSD, with my WD being my data drive. I have the most recent BIOS for my mobo, all my chipset and graphic drivers, all windows updates.

Here are some examples of the event logs:
Error - WHEA-Logger - Event ID 20
The computer has rebooted from a bugcheck. The bugcheck was: 0x00000124 (0x0000000000000000, 0xfffffa8004b57038, 0x0000000000000000, 0x0000000000000000). A dump was saved in: C:\Windows\Minidump\032810-11949-01.dmp. Report Id: 032810-11949-01.

Error - BugCheck - Event ID 1001
A fatal hardware error has occurred.
Component: AMD Northbridge
Error Source: Machine Check Exception
Error Type: HyperTransport Watchdog Timeout Error
Processor ID: 0
The details view of this entry contains further information.

I have done a Memtest overnight, resulting no errors. I have used OCCT, normal length (1hour), on both medium and large passes (to test CPU and NB/RAM, respectively). I've ruled out a virus by scanning with Symantec Endpoint and Malwarebytes.

I've done research on everything the errors tell me, and its very vague, ranging from audio/video device conflicts, bad RAM, bad CPU, HDD settings in the BIOS, bad volts to the NB, bad OCing, out of date drivers, etc.

I have all the minidumps from the crashes. I don't know how to read or understand them, so I was hoping if someone could and hopefully pinpoint my problem.

I'll be glad to provide any more information.
Any suggestions would be helpful.

If I had a nickel for every time I have seen the old 124 code lol

CPU = fail for what ever reason. But it is a CPU fail code.

Fix for me was to re think clock setting and bios settings.

volts, timings , clocks any of it could be to blame.

also seen it if NB overheats. Also see it if the NB don't have enough volts ETC.

Thanks for the reply.

Do you have any idea what settings i should try for the NB? The M4A79XTD EVO BIOS has a lot of settings for OCing, or underclocking, in this case.

I suppose I could try slowing down the RAM timings, giving it some more volts too.

And what about the HT settings? I've only ever messed with the multiplier with BE processors
