You have a choked down and bloated C: drive and need to create some space on that drive.
You also need to free up some ram usage and CPU resources which is creating a very sluggish PC.
Run 'Disk Cleanup' which can me found in the start menu under Programs / Accessories / tools or just type in Disk Cleanup in the Start Menu search box. Run this program regularly as it's a good housekeeper.
Clear Internet Cache permanently:
Open IE8 and if there is no Menu Bar showing, press Alt keyboard button.
Go to Tools / Internet Options / Advanced tab / tick 'Empty internet files when browser is closed'
Unfortunately nowadays, new PC's come bloated with Software and then sometimes a few undesirable programs are added by the owner
Unnecessary software programs (bloatware) that could be uninstalled and were probably pre-loaded on your PC when purchased (most of them):
HPTCSSetup
HP Quick Launch Buttons 6.40 H2
HP Customer Experience Enhancements
HP User Guides 0128 (1.00.0000)
HP Total Care Advisor (2.4.4941.2798)
HP Doc Viewer (1.03.0001)
My HP Games ([removed])
Microsoft Live Search Toolbar (3.0.541.0)
(HP) ESU for Microsoft Vista (1.0.0)
ProtectSmart Hard Drive Protection ([removed])
HP Active Support Library ([removed])
HP Total Care Advisor (2.4.6651.2902)
HP Update (5.002.005.003)
HP Help and Support
([removed])
Sweepi 5.4.00 (a performance enhancer)
Free Window Registry Repair (registry cleaner)
Google Toolbar for Internet Explorer (6.6.1015.36)
Adobe Community Help (3.0.0.400)
Adobe AIR (1.5.3.9120)
Acrobat.com (1.1.377)
Adobe Media Player (1.8)
Abode Reader could also be uninstalled and replaced with 'Foxit' which would free up some more space:

When installing, untick all the extra add-ons offered, regardless if it says they are part of the free agreement. It will still install.
Don't forget to defrag. your PC when finished with all of the above and then re-run Overdrive and post the URL with your next post thanks.
A Tech. here will then probably get you to run a small program to check out your start-up Menu and see what software does not need to start at boot-up.
Cheers,
Lee
