Yes you can.
You can invoke the System Restore tool by running:
in either Start, Run or from Task Manager, File, New Task.
But it sounds like you may have some malicious software on your system (malware) that is preventing your desktop from loading properly (no desktop icons?) so a System Restore may not help you in the way you think it might!
If a SR doesn't get you going, you should consider posting to the Am I Infected forum for expert assistance.
If SR does get your going, then you should do some malware scanning as the next step.
