Slow Start Up - Windows 7

I'm trying to sort out a friend's laptop, which is about 1 year old. Start up takes about 10 minutes (Windows logo all that time), and this started a few weeks ago. I ran a scan with Malware and found a few infected files, which I deleted, but that's made no difference. Even after start up the computer runs very slowly.

I've checked event viewer for the boot up log and found that btusb.sys could be a problem. It may have got corrupted. If so, how can I install a replacement file?

Any one got any other ideas as to what the problem could be?

A repair install or a new install might be the way to go.A bit of info on btusb.sys http://www.computerhope.com/cgi-bin/process.pl?p=bthusb.sys

Or try this http://www.soluto.com/ very useful for listing startup progs etc.

Its a bluetooth system file from Microsoft part of the op system.

search type sfc /scannow

windows should scan and replace any missing / corrupt system files (could take sometime to complete the scan)

Thanks.

Scannow keeps stopping at 46% and then says it can't perform the operation. I'm running it as administrator.

The recovery disk is in a separate partition. Can I access that to repair the bthusb file?

TRy updating / reinstall the Bluetooth drivers in Device manager

Still trying to sort out this laptop. It seems to have serious problems and so I'm going to do a clean reinstall.

However, I need to back up data and files and the laptop is far too slow for all the data to be backed up (it also freezes in the middle of backup).

Therefore, I've taken out the hard drive and put it in an external caddy via USB, but I can't access the Documents and Settings folder (and acouple of others). How do I make these accessible?

Thanks

The problem is my laptop's OS is XP Pro and the external drive is from a Windows 7 laptop, so I don't have the tabs shown in the example!
