I run Windows 8.1 on my PC and my work laptop. Yesterday I had 2 bluescreens on my laptop (never had them before on that machine) and today I had like 5 bluescreens on my PC.
All the bluescreens on the PC and 1/2 on the laptop were BAD_POOL_HEADER errors. They happened in completely random moments: browsing the web, watching movies, using Hyper-V.
The things that are in common between the 2 computers:
- the same OS - Windows 8.1 x64
- up to date system (maybe its something about Patch Tuesday updates?)
- they both run Hyper-V
- there are some common applications like Opera, SQL Server and a few others (most of the applications are different on both computers)
I looked through logs and they say that there was a reboot after error checking and the information was dumped to C:\Windows\MEMORY.DMP I can't see such a file even though I turned off hiding hidden files and hiding protected OS files.

Have you browsed Windows folder as administrator? Could you check whether there are some dumps in C:\Windows\Minidump ? – ge0rdi – 2015-03-14T18:43:51.107
I always use the admin account. I didn't find any methods or browsing folders as administrator. There are a few files in Minidump but I cant read any valuable information from them. – BuahahaXD – 2015-03-14T18:54:12.167
Were some of those minidumps created at time of BSODs? Could you upload them somewhere? Or at least post output from Windbg (ideally with symbols configured). – ge0rdi – 2015-03-14T18:56:58.230
Yes, they are from the times of bluescreens. I'll upload them in a minute. – BuahahaXD – 2015-03-14T18:57:47.323
http://1drv.ms/1EeNygL - here are the dmp files from the Minidump folder – BuahahaXD – 2015-03-14T19:01:51.113
1The crash happened because
vmswitch!RndisDevHostCleanupMessageOpContextfunction freed invalid memory. Vmswitch.sys is part of Hyper-V (Network Virtualization Service Provider). So there may be a bug in it. It's really hard to tell anything more (at least w/o full dump). Try to search Google for vmswitch+BSOD combination, maybe you'll find something that will help you. – ge0rdi – 2015-03-14T19:18:43.500Let us continue this discussion in chat.
