Solid-state drive, like a Flash drive?
No, no guide, just plug it in
Your next question on the slowness of your computer
There are a number of software tools to run, including:
CCleaner
Antivirus
AntiMalware
CheckDisk
Xp or
Vista
Defrag
Startup
But it also depends on what you have installed and presently running
ie Norton AntiVirus can slow a computer down, and so can many others (especially Internet Security softwares)
Drivers and Security updates can also slow systems down if not completed as well
Plus also Windows corruption (Registry; System Files; PageFile)
There's also Hardware
Your 128Meg video card for instance, may be too low for what you are using it for, so then Windows will try to compensate with your Ram and CPU Processing
Ofcourse you could have faulty Hardware too (Like HardDrive, Ram; or even a build up of dust around your CPU)
This list is too large to continue
And your questions are too general to understand
