Hp 530 laptop is very slow and freezes

Well, The problem can be caused by many many reasons such as outdated hardware, overload startup programs, corrupt registry issues, too many junks, virus attack, poor security software taking too much system resources, remnants of uninstalled applications etc. The fact is, you should keep some system maintenance job regularly. If you don't want to do these manually, try the hp speed up tool http://www.speeduphp.com/ to give a free & full scan of your slow HP PC to find & fix all possible issues.

Meanwhile, upgrading hardware configuration (add RAM, change a new video card, larger-volume HDD etc) can be a fast yet effective way to improve your pc performance. But that won't be the most economical way, as you know you can't always afford to do that.

Hi.

This laptop has SATA 2.5 hard drive. A common upgrade for this laptop is a 250GB or 500GB disk.

If the computer is slow, the part to upgrade is not the disk but more commonly the RAM.

This laptop mounted 1GB RAM that must be upgraded to 2 GB. You will need to install two 1 GB DDR II-SDRAM (667MHz) memory sticks.
