Windows 7: Random BSOD and freez

07 May 2012   #1

Windows 7 Pro x64
Random BSOD and freez


After getting rid of my last problem (, my computer got stable for a week or so (also did a new OS install). Then it started again. This time it wont shut off but freez or BSOD (only on cold starts).

- The computer is not overclocked.
- Temperatures are stable
- CPU test shows no error
- VMT shows no error
- Prime95 shows no errors

How long did you run the hardware tests? Prime95 should run for several hours on Large FFTs to get a good reading.

It's difficult to figure out what to work with here. There are no crashdumps, and your syslog and all other info is in Norwegian, so I cannot read it. Looking at your previous thread, you had an issue with RAM. Have you done another RAM test on the new memory recently since these problems started using Memtest86+ for 7+ passes? You want to make sure that this new RAM isn't bad either, and also incompatibilities with your motherboard can also explain the RAM issues.

However, I can't see how this would be related to freezing. Commonly freezing issues come from CPU, Mobo or PSU issues, primarily it being CPU in where the CPU locks up and cannot escape its current state, so everything is held up. Video card can also cause lockups due to failure to refresh the display and respond to the system.

If you want a few more hardware tests, I'll post a copypasta of a list of hardware test I recommend to people, available below:

RAM: Memtest86+ - 7+ passes
CPU: Prime95 - Torture Test; Large FFTs; overnight (9+ hours)
GPU: MemtestCL - Run twice (if any of the tests work on your GPU; ATI cards will need to install the ATI APP SDK as it requires OpenCL)
Drives: Seatools - All basic tests aside from the Fix all or the advanced ones.

All of these (excluding MemtestCL) are included in the UBCD if you prefer a Live CD environment (which is the best environment to test hardware on). Note that Prime95 currently does not work on the UBCD. Also, please provide us temps/voltages using HWInfo with Sensors only option checked. Log two 30-minute instances: one for idle, and one for high load.
