After clearing the bin the PC runs slow

So you only have 2 problems:

• it is very slow
• it crashes after 10 minutes.

correct?
After doing Troubleshoot Application Conflicts by Performing a Clean Startup it's still slow? Does it crash? Don't forget to revert the changes after testing "Return Windows to a Normal Startup Mode" in tutorial.

Whatever you do normally.
Is pc slow in clean boot?

Hellbinder said:

Yeah, everything is back to normal in clean boot, so i work down the list of step 2

so clean boot wroks perfectly? Fast and no crash?
If so.... enable services 4 by 4.... and startup programs 4 by 4.... until you find the culprit.

I´ve gone thrugh the whole services tab, found nothing,
gone thrugh the Startup tab, activated them and now there is onely one left,
named "G Data Personal Firewall", so i wantet to against test it, but it wont let me reactivate it, it also wont run it over Normal Startup, when i Chose Normal Startup and press apply, it switches back to Selective Startup with onely "G Data Personal Firewall" deactivated...

But is system still slow? Does it still crash? Still the boot0: error?

What happens if you put a checkmark at "G Data Personal Firewall" in msconfig? What happens if you press apply afterwards?

So

End press OK
