Windows 7: BSOD at seemingly random times

BSOD at seemingly random times

A few months ago, I received a computer secondhand, so I wiped it and installed Windows 7. Now it occasionally BSODs at random times. Sometimes it is when I have already been using the computer for some time, and sometimes it is before Windows is able to fully start up. I cannot discern a specific event or action that I am doing to trigger this. It seems to happen when the computer is left alone for a while.

My Google-Fu has told me that it might be the driver "ntoskrnl.exe," but I'm not sure and I don't know how to fix that. The stop codes have been 1A and 1E.

The BSOD reports a memory corruption.
Code:
BugCheck 1E, {c000001d, fffff88000d7cc00, fffff88009e32bc0, 0}

Probably caused by : memory_corruption

If there is no error, enable Driver Verifier to monitor the drivers.

Before enabling DV, make it sure that you have earlier System restore points made in your computer. You can check it easily by using CCleaner looking at Tools > System Restore.

If there is no points, make a System Restore Point manually before enabling DV.

Thanks, HarriePateman. I ran Memtest86+ overnight and it went through 12 passes with 0 errors. I then tried driver verifier. Nothing happened for a long time, but then I got a different BSOD: C1. Apparently the solution to this problem is to "obtain a backtrace of the current thread. This backtrace will usually reveal the source of the error." I have no idea what this means. :/

Here is the dump file. I am still unable to determine the exact cause.

It may be worth noting that I noticed my speakers were unplugged. Right when I plugged them in, the computer gave a BSOD. It kept restarting and would not turn on. I left it off for five minutes and it turned back on. I have NOT been able to replicate the BSOD by plugging in and unplugging the speakers. They work fine now.

Huh, thanks. An edition of Avast was giving a different computer BSODs until I downloaded the old installer. I wonder why Avast seems to have these issues.

If you don't mind me asking, how were you able to get detailed info on the bluescreen? I was using bluescreenview and it didn't show anything too detailed, like being about Avast or anything.

Bluescreenview is inadequate for diagnosing BSOD's....if often highlights what modules were affected by the crash, but not the cause. Proper BSOD diagnosis is done using WinDBG, this is what I used to locate the cause of the BSOD's.
