All MiniDumps cite "memory corruption" as the cause which is Related to Driver Or Software Errors. The 2 errors in the MiniDumps were 0x50 and 0x7E errors which are Device Driver and Software problem related.

One Driver is cited "klif.sys" which is associated with your Kaspersky Software.

Have you recently updated your Kaspersky Software?

You should try uninstalling it and reinstalling it again.

Thanks for quick reply. I'll try it.
Can you tell me how did you know these infos? Maybe I can deal with it next time by myself. I'm really a newbie.

Here are some links that would help you diagnose these problems in the future.

Troubleshooting Windows STOP Messages - http://aumha.org/a/stop.htm
This link is very helpful in narrowing down the actual cause of a Stop Error and what in a computer may affect it, e.g. Hardware, Software or Device Drivers, some errors can have more than 1 possible cause, and some Stop errors can point to specific areas so less testing is done.

Debugging Tools For Windows - http://www.microsoft.com/whdc/devtoo...g/default.mspx
Used to read the MiniDumps, all instructions on how to use it and set it up are on there as well.

Then along with this use Hardware Tools to test the Hardware like Memtest86 (RAM), Prime95(RAM and CPU) and The HDD Manufacturer Provides Tests For The HDD. Use Google as a good search for File Names you don't recognise to Diagnose Software and Device Driver problems .

This Info Should help you get started, if you want to know anymore you can ask.
