I was testing another GPU the other day and, as it was not working properly, I reset the CMOS battery to see if that would have any effect. The GPU still didn't work so I reverted to my old ones. To clarify, I made sure to restore the time/date and settings in the BIOS, however since doing so i've had some strange behaviours: HWInfo64 crashes after launch with these error codes, Spoiler: Error codes Problem signature: Problem Event Name: APPCRASH Application Name: HWiNFO64.EXE Application Version: 184.108.40.206 Application Timestamp: 59fad937 Fault Module Name: ntdll.dll Fault Module Version: 6.1.7601.23915 Fault Module Timestamp: 59b94ee4 Exception Code: c00000fd Exception Offset: 000000000004f2fa OS Version: 6.1.7601.2.1.0.768.3 Locale ID: 2057 Additional Information 1: 4532 Additional Information 2: 4532f229f4f8256e89a18c763aa82c0c Additional Information 3: b4e1 Additional Information 4: b4e1053f1a3c397b22e78f93ad7acc9d Read our privacy statement online: http://go.microsoft.com/fwlink/?linkid=104288&clcid=0x0409 If the online privacy statement is not available, please read our privacy statement offline: C:\Windows\system32\en-US\erofflps.txt Steam still runs just fine, but I get an error code on startup, GPU-Z still seems to work just fine, but gets various errors when starting up, As far as I know, there are no other issues I have. This feels to me like one of those times where i'm missing something really simple, but I have no idea what. The laptop is an Alienware M17X R2 for reference.
