I am aware this appears to be a fairly common issue, but I have spent a long time attempting to solve this but without success so any help would be appreciated.Įdit: I disabled SLI thanks to your suggestions and now Source games run again which is good. I have an idea that it may have been caused after I took my PC out of standby which is something I rarely use but after each time I did it recently, the problem occurred.
The games I tested were: Portal 2, L4D2, Dota 2, CS:GO and HL2. I'm not really sure what induced this or how to fix it but it is quite frustrating. Verifying integrity of Source game's cache The first time it happened, games would just instantly close with no error message and I fixed this by running the command steam://flushconfig but yesterday the error occurred again now saying the exe has stopped working. This only started happening within the last few days and I haven't encountered this problem in the 2 years I've had this PC.
