Aaaaah!
Now I know what this sound is [through the speakers] that I keep hearing every time I login to Windows - and it makes that noise 4 times because there's 4 'portable drives' that has a problem!
Every time I login to Windows, I get a low "dudu-dun" sound coming through the speakers. It's been making that sound for a few weeks now, and I never thought to check that it meant "Device failed to connect" (confirmed by the default sound it makes) until you said the problem was the storage devices.
I've clicked 'disable' for each of the 'Portable Devices' (and they still have the ! next to each one) - does that mean it's fully disabled then now? Also, which one is the 'USB connection' in device settings [the same as Device Manager?]
For the mouse: In Device Manager, It's got 2 of them - and I'm not sure which one my mouse is using:
HID-compliant mouse (which is fine), and
Microsoft PS/2 Mouse (which has Code 24 next to it)
How do you re-install the mouse if you need the mouse to install it again?
I can't really give you much info on when, how, in what circumstances I get these crashes, as I wasn't doing anything to do with the portable devices at the time - I was just browsing the internet (with Firefox)... and maybe perhaps also running a virus scan
The whole background to my videocard can be seen in
this thread (and the one's linked to it). There's a reason I haven't tried sorting the graphics card out yet, which is a little long-winded to go into here.
