Try cleaning out your temp files ect. with an app like Ccleaner for example:
Download:
CCleaner (freeware)
|MG| Free Download - CCleaner Slim (No Yahoo Toolbar, English) 1.41.544
Run the installer, and uncheck the option to install Yahoo toolbar (unless you want Yahoo toolbar).
Once installed, run
CCleaner click the Windows [tab]
The following should be selected by default, if not, please select:

Next: click
Options click the
Settings tab
Uncheck: "Only delete files older than 48 hrs.", click Ok
Then click
Run Cleaner (bottom right) then
Exit
Maybe that helps.
