Windows 10: Lsass.exe error causing machines to restart - EventID 1015

Hello!My organisation has recently encountered an issue in Windows 10 with lsass.exe failing and causing machines to restart, seemingly at random. We first discovered it from our MDR flagging it as a Werfault.exe exploit, so naturally thought they were blocking the process from running properly which was causing the crashing. We told our MDR team who confirmed it as a false positive. We then tried to disable that particular threat detection to confirm the root cause yet still noticed system crashing due to lsass.exe failing. In event viewer this is what we receive:Another speculation we had wa

Possible Causes of atikmdag errors

I was courious to see how many different causes there are to the infamous atikmdag.sys error that strikes widely across and has so for a long time, I am getting it myself also and it is really starting to wear me out. It is pretty annoying having a $520 Readeon 3870x2 card if you can't use it without errors.

So first of all, here is the apparant reason for my atikmdag error:

When I play a game, regardless of settings, clocks or anything else, the fan speed wil not be adjusting and the card will get hotter as it performs. As soon as the card gets hot enough, my system will attempt to speed up the fan and as soon as they do, I get the atikmdag error. I never hear the fan of my card go beyond 30% fan speed unless I push it using Rivatuner.

Anyone else got other apparant reasons?

By the way, here are the steps I have been trying to fix it

• Renaming atikmdag.sys to "atikomdag.sys(old)
• Set fan speed profiles in Rivatuner depending on temeprature thresholds
• Setting fixed fan speed in Rivatuner
• Installing only the ATI drivers without Catalyst Control Centre
• Replacing RAM blocks
• Trying older drivers

I have probably tried a few

 

splwow64.exe is causing machine to lock

splwow64.exe is causing two issues. The first is EXTREME slowness in Excel, and the second is that any PDF I try to print is locking up the machine. I'm running Windows 10. I have searched on Google for answers and have found that this has been a known
issue for years and apparently a hotfix was available for Windows 7 and Server 2008 R2, but I cannot find a hotfix for Windows 10.
