Why is my computer running so slow?

"If your laptop is running more slowly than usual or has become increasingly slow over the past several weeks or months, see the Acer Aspire 5253 Is Running Slowly problem page for possible problems and solutions.

The most common cause for this behavior is a fragmented HD in WinDUHows, a full HD, or, eminent HD failure (depending on the age and care of the HD).

Different versions of OS X require different amounts of ""free space"" (empty space on the drive) anywhere from 7-20% depending on the type of drive (SSD drives need more), and the size of the boot drive.

So if your boot drive is nearly full that could be a reason. Also running a machine without a hard reboot (complete shutdown and restart) can cause some issues as RAM that should be completely released when you quit a program isn't, or the RAM gets fragmented and large segments needed for some applications are available so VRAM gets used (VRAM is always slower than actual RAM).

Lastly if you've recently started using a new application that requires more physical RAM than you have you could see this behavior..
