No start or control panel crashed computer Help!

Curious if anyone can help with this. Daughter did a system restore on slow computer. Now can't access start menu or Internet. Tried using task manager as that is only option to get stopped programs running, eventually got an Internet connection but still could not search. Almost got a system reset when it locked up again. Using safe mode still did not allow me to restore nor safe mode with networking. Every time I have to begin again from scratch as the drivers for most functions stop working again. Get checking media text at startup now and then the same brutal loop all over again. HELP!! Thanks
