No, the hardware shouldn't be damaged. You most likely fragmented some files. A general system cleanup should help.
Put in the OS disc-->start-->run-->sfc /scannow
Download ccleaner, and run the registry tool. You may need to run it several times to resolve all the issues.http://www.piriform.com/ccleaner
When done repairing the registry, you may want to use ccleaner's file/application cleanup tools to delete garbage files.
