Q: When I'm typing it seems slow or lagging, I don't know if it could be the Dell OEM keyboard. And also when I open a program it seems slow! Does anyone here have a solution?
A: Restart your laptop, if it continues that way, it means there are a lot of programs on your machine and are running in your processes in task manager therefore no enough memory for paging file. What i think you should do is unistall programs/software that you do not use often. You can keep ur files in Pendrive or removable object. perform disk clean and always keep ur antivirus updated, scan regularly. clear cookies, history, cache files, e.t.c. all these makes one's machine unique. If it stills behaves in that manner, reinstall keyboard driver from this site. support.dell.com
