Logitech G19 problem

[Jan.B]

So I have a G19 (my previous keyboard, have it for some years now) and for a couple days now my test-bench has been acting up strange at booting with Windows (Win7 x64 Pro). Since the OS is installed on a SSD (Corsair Force 3 120GB)
I tought there was something wrong with that but after hooking it up somewhere else it was working just fine. Then I tought it had something to do with the OC I did on the cpu, wich would have been strange since it's clocked that way for a couple months without any issues and has always been cooled down properly (I7 2600K@4.5Ghz/1.28V ~ av temp: 38-45°c idle, 65-68C° at max load ) with a H100i and has recently got a costum loop (switched that for the H100i) with a 3x120 rad. And yes it's a stable clock, had it tested with prime95 AND intelburn (altough that one is not recommended, does more stress on the cpu than prime95).

Now I'm getting to the G19 part.
When I bought a used HD5970, the previous owner saw the G19 at my bench and stated that the thing has caused several ppl some problems in the past, but since I never had any problems with it what so ever, I never took it seriously... until now..

The thing is, I was thinking about what he said and after trying everything else but removing the Logitech keyboard drivers, I just had no other option left but to try it..and for some reason it worked.
So now my system is running fine with the keyboard still hooked up but working with no drivers.
 

The problems I encoutered were as following:
- Slow Windows 7 boot after log-in
- taskbars were taking forever to open (more than usual, made it look like a old hdd was running it while it was infact an SSD)
- ctrl+alt+del did not work, infact it resulted in a error message saying that it was not possible
- black screen with nothing else besided the  mousecursor

I've tried system restore and everything else but nothing seemed to work, even resseting my cpu to it's factory settings  (had it saved just in case, hurray for OC-profiles!) did not resolve the issue.
So I removed all drivers and programs that had something to do with the keyboard and it's running fine since then.

If any of you ever encountered something simillar then please let me know and if you think or know it's something else causing this and the G19-thing is juist coincidence then please let me know aswell.

Cheers.
