HiJack log posted at the end!

I am having so many problems with my computer! All help is deeply appreciated.
The problems are as followed:

1. I am having problems changing my background.
2. Everytime my computer starts, I see a blue screen that says "Disk needs to check files"
but it never completes checking them.
3. I keep getting sound when there are no open windows.
4. My computer runs awfully slow.

For a start, you have look-to-me adware.... so go here http://www.f-secure.com/tools/f-look2me.zip and dl f-look2me and as an administrator, unzip it and run the .exe. Reboot.
I would like you to download CCleaner from http://www.ccleaner.com/ and put it in a new folder. You should aim to keep this one for general use. I set it from the install checkboxes to only open from the recycle bin. It's just a neater thing.
Now go to grisoft.com to update from Ewido 4 to AVG antispyware 7.5. Uninstall Ewido then install AVG A-S 7.5. Update it.
Get Adaware SE Personal from http://www.lavasoft.de/software/adaware/
- install it. Update it.
When it finishes updating files go get this free beta [blbeta.exe] from http://www.f-secure.com/blacklight/ and install it also.
Finally go here to get Spybot S&D :- http://www.safer-networking.org/en/download/ Update it.
You have a couple of other trojans in there also, so memorise these instructions... or copy em to notepad. Or just use Opera...
Ok, you're done with the net. Shut it down. Disconnect...
Rclick your recycle bin and run CCleaner. [or go to its folder and dclick ccleaner.exe] You will lose a lot of handy stuff like histories etc... but there is a job to do...
Now go into safe mode [Restart, F8 and select Safe Mode and Enter.... You'll get a dark desktop with icons etc...]
Note: Close all open windows, and DO NOT USE the computer while these scans are running. If Explorer or other programs are open during the scan that means certain files will also be in use. Some malware will insert itself and hide in areas that are "protected" by Windows when the files are being used. This can hamper a scanner's ability to clean properly and may result in reinfection.
- Run the blbeta.exe.
- Run AVG A-S as you used to run ewido. Start AVG Antispyware, do the complete system scan. Click "Apply all actions" to place any infected files into Quarantine, and only then click on "Save Report" to view all completed scans; click on the scan you just performed and select "Save report."
- Do a full Adaware scan and remove all the problems it finds.
- Run SpyBot S D. Create the registry backup, then check for problems. Select and fix problems.

Reboot into normal windows mode... if everything appears to be working you must now remove all old system restore points... do this by turning sys res off then on again for all drives. The path to this is via Start > all programs > accessories > system tools> system restore - use the link "system restore settings", and check turn off sys res for all drives, Apply... AND THEN UNCHECK THE BOX, AND APPLY. The reason for doing this is that some trojans write themselves into the System Restore files, and in there they are totally safe from anything.
Run HT again and post the log, and retell any problems you may still be having.

Thank you so much. I've downloaded, installed and updated all the programs except for the F-Secure Blacklight. It says either my PC settings or Malicious adware is stopping it from working.

Then rerun Adaware in safe mode, and once back in normal windows mode try this scan online:- http://www.pandasoftware.com/products/activescan? Give them some details, and follow the scan buttons.
Run HT again and post the log, plus the Panda log.
