Devices and printer folder emtpy, no recent programs or document list and other problems
I am having a weird problem with my computer, I have Windows 7 which was the upgrade from vista. I was in google images and went to a few sites then all of a sudden my screen went blue like it was shutting down and I got paranoid like it was a virus so I pressed power off. When it came back on it the whole windows theme was changed to the standard Windows 7 (I usually change the desktop and menu etc to classic theme) and I tired to change it back and it did a little, the bottom task bar though is still double in height then usual. The folder icons were huge allover my desktop to I ad to shrink them. In the taskbar all similar programs (multiple IE windows etc) group together and I can't ungroup them. I cant add any shortcuts to the taskbar, can't pin anything, no recent programs show up in the start menu, no recent documents even when I try to fix that in the customization tools it doesn't accept any changes.Pretty much any changes I try to make it will not accept even with start meno privacy option to show recent files and programs, the changes do not actually take effect.
Also printers wont work, when I open my devices and printers folder it is empty. I searched for hours online help and I think I got my printers working again but the device and printer folder is still empty and though my printer works I can't set it to default.
Also after I had shut down because I that I had a virus it looks like when my computer turned back on that IE8 installed itself and I had the version before that because when IE opened all those annoying tool bars were on the top of my browser (ask.com, google, etc) so I had to delete them. All my bookmarks were reorganized in alphabetical order.
I just did a system restore to a restore point 36 hrs ago (Friday morning May 13) but it did not fix anything and even new files that I had saved on my desktop from Friday to today that would have been lost from doing a system restore were still there so it was as if the restore did not really work or went through though it said it did. The only thing the system restore did was to once again change the theme back to the standard Windows 7 which I had to try to change back to classic display.
I don't know what the heck happened to my pc but it is not working like it should any advice?
