[Error] machine crashes on Win+L key combination

[Fr33m4n]

I've got this really wierd problem. If I press the key combination to lock the workstation, Win+L, my machine freezes for a few minutes then reboots. I think there may be a BSOD in there somewhere but it flashes by so quickly I'm not sure if that is what it is. After the machine has rebooted I ran Crash analyzer from winternals and determined that my graphics card, xfx 7800 gt, was stuck in an endless loop and that the problem eather was driver related or hardware related. I got the forceware v81.98 installed. But to me it seems very odd that the gpu drivers should be the source of the problem with the Win+L key combination. Because it only happens then, and it allways happens then. I've reproduced it 3 times in a row just to make sure. I probably should add that I recently added a Saitek cyborg evo force joystick to my system and that I installed ms flight sim 04, but that does not seem like a logical source of my problem, then again when were computers ever logical. So, any help appriciated. thx in advance.

check the event manager too, just for the heck of it.

i'd guess it may be a graphics driver problem. you could try a different driver. you might want to check OmegaDrivers as well. his are optimized.

I second atomizer's post.
