Windows 7: Windows 7 ... Half Crash....?

I ungraded to windows 7 few weeks ago, and i had a few problems when i did but i have sorted most of them now. Now i have another problem.

Now and then when i am on my PC it crashes sorta, my mouse stops working but i plug in another one and that works fine, my USB wireless adapater stops working and stops picking up the internet and my stereo i have plugged into my computer the sounds goes mental and screechie and then stops, when i say it half crashes as i can still use the keyboard and use the tab keys to get on the start menu to shut down.

When i shut down it takes 2-3 times longer then it usually does when it hasn't crashed.



I really have no idea why it crashes, as i am not doing anything i can tell that i am making it do that, maybe drivers or something?

anymore have a clue whats happening? please ask more quesiton if you need more information about it.

Thank you,
Regards,

Edit:
I don't know if this is anything to do with it but i have just found out that when i go on device manager there is a yellow error sign next to my coprocessor and when i try update it doesn't update it.

Anyone? or have i found something to puzzling. lol

Update your chipset drivers... let us know what happens...

is the mouse usb, or ps2?

The mouse is USB, so is the wireless adapter.

I take it nobody knows how to fix this then.

It only seems to be when i plug in my USB wireless adapter it crashes, sometimes it all works fine, other it doesn't like this morning.
