Hello

I have a dell desktop which is presently experiencing some technical hitches. It frequently displays the information "Low on virtual memory". With the aforesaid information having been displayed every application running begins to act incoherently. I find it difficult to save, delete as well as perform other tasks.

I have tried to defragment the drive as well as carry out a disk scan. I would like to know what the causes for such a problem are as well as possible ways of rectifying it

Thanks
