Windows 7: APPCRASH & BSOD w/ All games

I'm having appcrashes randomly between 30m and 6 hours.
I still can play games very fast ultra graphs and lowest with high fps but i still get appcrashes and sometimes even bsod's.

This might be a memory or graphics card problem but i want to be absolutely sure wich one it is and if it isn't because of malicious software.



Thanks in advance.

Two points of order.

One double posting is not a good idea. It splits the support.
two when you post it needs to be in english for us to help you

Just a heads up

I'm fully aware of that but i had major difficulties posting this thread, i had to do it over 5 times and it did not show so i got a little sloppy and thought to edit it but when i edited it it showed up 2 times... I'll try to delete this thread and reply instead of edit in the future with new info.
Thank you so much for your time i hope you can diagnose the problem for me ^^.
