I can't help you with your System Restore problem, but the 'problem with shortcut' problem could very well be virus or spyware related.
Moderator Bob Proffitt's Anti-parasite suite is a good starting point. Everything is free, but you might have to use google for recent download places. Read http://reviews.cnet.com/5208-6132-0.html?forumID=32&threadID=1313&start=0 and be sure to run all the tools.
Do you have a current anti-virus program running? It's really necessary.
Hope this helps.
Upon start up, I receive about 30 error messages regarding "Problem with shortcut." Each message pertains to a different file. Each file name is titled some name I am not familiar with. Hyroglyphics, if you know what I mean. Anyway it takes about 10 minutes for each of the boxes to pop up, and I can proceed with using the PC. I attempted to use System Restore to go back to a date prior to the problem. But System Restore won't allow me to go back prior to the current date, which I absolutely don't understand. That's its purpose, isn't it??? When I go to the System Restore screen, a calendar pops up highlighting today's date. There is a button which says it will take me to the previous month, which is when I want to do the restore, but it doesn't change the calendar. The help screens don't tell how to create a restore point as far as the format goes, ie., date, time, etc. So I can't figure out how to do that either. I don't understand enough about the computer to get any further without help. Anyone have this problem before? If so, do you know how to fix it???
