Hi Mark

If your Dell is 10 years old I hope you have changed the HDD, if you haven’t then do so immediately as you are running on borrowed time. (On average in full use most HDD have roughly a 3 year life span which can be extended to about 5 years in a domestic environment)

Remember if the HDD fails, and you have not backed everything up, you have lost everything. (There are companies that can retrieve data off a failed HDD but they cost an arm & a leg)
