Problem: - The computer, after a few reinstalls and a few Win7 problems upon other problems (trying to get the latest nVidia drivers installed, for instance), BSODs seemingly randomly. It has so far done it at the following times:
* During regular Excel use.
* Moments after booting into Windows.
* While browsing YouTube videos.
* Moments before system shutdown.
The error shown on the BSOD is the following: ***STOP: 0x00000124, which I've looked into and it seems it's usually a hardware issue?
What I've Tried:
- Installing up to date Graphic Drivers: I could not for the life of me getting the latest "safe" nvidia drivers loaded. They kept failing over and over, and caused BSODs 4/5 times. I then tried installing the latest beta drivers in Safe Mode, which worked, so those are the ones I'm running. Didn't stop the problem. - MemTest86 (the 4.0 version that runs from a bootdisk) has returned some errors. The first one was returned whilst testing both sticks at once, then I tested each individually and got no errors, then I updated my mobo RAM settings and tested both again, at which point I got the second and third set of errors:
*Error 1: TST: 8, PASS: 2, FAILING ADDRESS: 001f79ebf4c - 8057.6mb, GOOD: 00800000, BAD: 08800000, ERR BITS: 08000000, COUNT: 1, CPU: 0
* Error 2: TST: 8, PASS: 2, FAILING ADDRESS: 001ea50dd48 - 7845.8mb, GOOD: 80000000, BAD: 8000008, ERR BITS: 0000008, COUNT: 1, CPU: 0
*Error 3: TST: 8, PASS: 10, FAILING ADDRESS: 001f79ebf4c - 8057.6mb, GOOD: 00000800, BAD: 08000800, ERR BITS: 0800000, COUNT: 3, CPU: 0
For all 4 tests I let it do 12 passes, basically let it run overnight. Not really sure what to do with this information?
- Reseating components: I've tried reseating the RAM and the graphic card, didn't help.
- Setting the voltage higher on the CPU: CPU-Z returned a voltage of 0.9 on my CPU, I upped that to I think 1.1 but it didn't help at all.
- Correcting the timings on the RAM: The BIOS stated my RAM was running at Auto speed (defaulted to 1333 anyway..) and 9-9-9-24 timings. I corrected the timings to 9-9-9-27 as per Kingston's website, and set the speed to stick at 1333. If anything this caused MORE memtest errors, although that's a chance thing anyway.
- Cooling: I bought a CM Hyper 212 Plus HS and installed it, I know Speedfan's temp sensors aren't too reliable but it's returning readings in the mid 20s to 30s for the CPU and 30s to 40s for the VGU.
What I Haven't Tried:
- Updating BIOS - scared of this as I've never done it before, and I know how dangerous it can be. Biostar offer a GUI version of their BIOS installer.. if that might help I'll try it?
- Better CPU - I'm aware my CPU is a little underclassed compared to most of the build, not sure if that can affect stability, though?
Not sure where to go from here... it's still Memtesting as I don't know what else to try, is there a way of finding out which RAM stick is bad if they both come back clean when tested seperately? Shall I just RMA the RAM? I know no errors are good errors, just.. haven't really been in this situation before. Any advice is appreciated!
