Hello, I have a laptop running the latest public update for Windows 10. As I turned it on yesterday I got four different error messages for four processes which included IAStorIcon.exe, TOASTER.exe, and DropboxOEM.exe. The messages read as follows:
 
IAStorIcon.exe - Assert Failure
Expression: [mscorlib recursive resource lookup bug]
Description: Infinite recursion during resource lookup within mscorlib. This may be a bug in mscorlib, or potentially in certain extensibility points such as assembly resolve events or CultureInfo names. Resource name: Arg_ExternalException.
Abort/Retry/Ignore
 
I get these messages and the computer won't let me do anything else, no matter which option I click on the messages the computer won't do anything else. I can move the mouse around and click on stuff but no programs open, the start menu doesn't open, Ctrl+Alt+Supr does nothing, right clicking does nothing. It basically only lets me move the mouse. I tried to boot into safe mode and the first time it gave me a blue screen of death with the stop code: CRITICAL PROCESS DIED. It loaded all the way up to 100% and then it STOOD there for half an hour, until I forcefully shutdown the computer. Next time I was able to boot into the blue screen that lets you use a restore point but the time of restore point was from after this problem started so it did nothing. What can I do and how can I do it? My computer is PRETTY much unusable after signing in so that COMPLICATES things a bit.
 
Any help would be greatly appreciated.Sounds like a very serious problem, I would perform a system restore.
