I have nothing but icons and nothing works

I have very little experience fixing computers but I am sick of paying for repairs. When every I start my hp mini all I can see is icons, there is no taskbar, no start button, and even my active desktop is turned off. So far I have tried many things. System recovery doesn't work, tried to run virus scan and Mcafee wont work, also I have gone into registry error and have not found anything in
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options

If anyone could help. I am not sure if it is problem with computer or a virus but I'm betting its the latter. Safe mode hasn't help either. Im looking for help on anything really but if I can restore or even run a scan I might have a better idea. PLEASE HELP.

I'm DOOMED without you!!

Thanks :S

Also my internet does not work....so basically nothing works anymore
