I am having trouble with my laptop randomly freezing, and the display goes blank/turns off. It does not happen in safe mode. It happened a week ago, and I fixed it by uninstalling the graphics card driver, and reinstalling. That however, is not working this time.
I also took covers off of the bottom and cleaned all the dust out of there to make sure things were not overheating.
In my system information under the problem devices, the Security Processor Loader Driver is listed with an error code that states this device is not working properly...not sure if that applies to anything here however.
I've ran virus scans, and they either come up clean, or with a few things which it fixes, and this problem still persists, so I do not think it is a virus/malware.
