You have to approach this systematically. The first obvious thing to look
for is a virus. Run your on-board virus program if it still works, and also
one of several on-line free antivirus programs, like the one at McAfee.com.
Then run at least a couple of adware/spyware programs downloadable from the
internet for free. If this doesn't clear things up, then try the restore
feature, presuming you are using windows XP. If this still doesn't fix
things, then try to do a windows reinstall without format, although this
often doesn't work. If the problem remains then you are forced to wipe the
drive and reinstall windows from scratch. Almost always these problems are
software related. There are trial versions of hardware scanners you can
download that will check your system for hardware problems, but it's
probably virus/spyware related.
