My Laptop is ver slow! What to do?

I have Lenovo laptop, which is running very slow, Please suggest me what to do.

Service it

Get it analyze it with an expert. MOST Recommended.

There are a couple of things you can do to make it faster.

1) Scan your laptop using an Anti-Virus. There might be some viruses slowing down your laptop. I would suggest Avast or AVG.

2) Open your control panel, and uninstall some unnecessary programs. Too many programs make your laptop slower.

3) Format a disk. This removes all non original data files from a disk. If you need the files in that disk, do a backup first. To format a disk, go to Computer, right click a disk, and select "format".

4) Format the whole laptop. This erases all data, restoring your laptop back to new. Do a backup first if there are some files you need. This requires a Windows CD, or download an ISO image from the internet and put it into a USB.

I would suggest trying the first and second ways first. If it's still slow\not fast enough, format your laptop.

Hope this helped, and good luck!
