Hello all,
I have been working in the engine for almost 2 months now without any problems - not a single crash, no strange performance problems - all good. Then today when I opened the engine as usual it crashed. as far as I know there have been no installations of any windows updates or graphics updates. they are all up to date. What can I do? It would be very important that I can render the project at the end of next week, it is a job for me.

I have verified the engine and deleted the local config file. This is the output log:

Any help would be greatly appreciated !

little update, still problems:
i updated bios, i deinstalled and reinstalled all the drivers. i updated windows. i reinstalled the engine. now the engine seems to work better, but still crashes, especially if i open my last project. any ideas what i could do?
do i need to reinstall windows?

Check your PC for faulty RAM , over temperature CPU or your Video Card.

as far as i understand they should be all ok. also run a RAM-test and didnt got any errors. everything works as always - do you have any suggestions what i should specifically check ?
