Windows 7: Constant BSOD's

Constant BSOD's

Hello.

So lately, I've been getting frequent BSOD's while multi-tasking on my computer. They're completely random and some days I can go all day without getting one. My second to last one said MEMORY_MANAGEMENT, while the last one didn't have an error message.

From a tutorial on another site, I used Microsoft Debugger to read the dump file and it informed me: Probably caused by : ntoskrnl.exe ( nt+70600 )

What does this mean and how could I fix?

I'm running Windows 7 home, 64bit. If there's anything else that you need to know, let me know.

Can we have your dumps please? [if possible]

Does it only happen when you multitask specifically? [as in is there any way you could remotely cause it to happen again?]

First thing I would try is running chkdsk /r.

Let me know!

I realized after I posted that it most often happens while playing World of Warcraft, but it has happened at other points.

And here is the latest dump:

Ok, boss. Give Memtest86+ a run for up to 10 passes and see if it craps its pants or not. If it drops a dookie, I'd put the blame on your ram, if not, give chkdsk /r a whirl and see how it favors. If it passes, run Prime95 for a few rounds.

Let us know what you find!

I ran Memtest86+ and Chkdsk, and everything seemed fine. However, as soon as I got to Prime95 and started it up, it crashed and I got another bluescreen saying "MEMORY_MANAGEMENT".

Which Prime95 test did you run?

If you ran the "blend" test, Prime95 will fill up your ram and toss numbers around inside it to random parts of each stick using the processor. If it plucks a bad string--so to speak--it'll crash.

If you did run the blend test, remove your ram stick and run it with one stick at a time until it crashes. On whatever stick it crashes on it's safe to say that stick has some issues and could serve a replacement.
