What slows down computers besides memory usage?

Q. I just deleted a whole lot from my laptop, and I ran a 'defragmentation' on the hard-drive, but it's still going really slow. Any ideas?
More detail: It's slow to open programs or new windows. There's a delay between when I click an icon and when the window opens.

A. Are you familiar with the Task manager? (Ctrl+Alt+Delete) The task manager will show you which processes are using you processor power and how much virtual memory.

What version of Windozes? Have you tried using a registry cleaner? Do you have a reliable anti-virus?

When I used to use Windozes, I had to wipe it about every 6 months and start over. It just seemed to get unstable after prolonged use. I now use Ubuntu Linux.

What operating system should i install on a VERY old computer?
Q. The computer again is extremely old, ie 5-6 years (integrated graphics, 1 gig ram, pentium processor, etc). Now i want to find an OS that is both simple to use and one that will run efficiently, especially for viewing photos and movies (obviously this is bottle-necked by hardware, but there should be differences in memory and cpu usage from OS to OS),

So what do you suggest? the new chrome OS, win XP, ubuntu?

A. Old machines run best on what they were designed for, But time marches on and computer os support runs out of steam. If your machine was designed for XP os then use it, upgrade as much of the hardware as economical and go from there. You may find it would be best to purchase a new machine rather then try to upgrade on your own. If that is not an option and you are determined then you should start with the memory, then the video card. If your machine is at least a P4 running at close to 2.0GHz then you will have a chance depending on your technical ability. If not then you should shop the internet for a used system that is within the price range of what you are going to spend on upgrading your machine. To answer your question Google Chrome OS is only to be used for the modern netbooks (condensed and stripped down laptop computers), Win XP was most likely the OS that was installed at the factory on your machine, and Linux Ubuntu is free and open source software.... XP is my choice

How to find my Linux System Information?
Q. I know how to find it on Windows. But how do I find my system information on Linux Operating system. Thanks.

A. Open the command prompt, it might be known as Terminal. The following commands will allow you to find your system information.

System Information
archPrint machine architecture.
df Shows disk free space.
duShows disk usage.
freeDisplay used and free memory on the system.
ipcrmProvide information on ipc facilities.
ipcsSame as ipcrm.
lsdevDisplay information about installed hardware via files in the /proc directory.
lsofList open files.
lspciList PCI devices .
pnpdumpLists ISA plug and play devices resource information.
procinfoDisplay system status gathered from proc.
pstreeDisplay a tree of processes.
runlevelFind the current and previous system runlevel.
straceTrace ssytem calls and signals for a binary program.
sttyChange and print terminal line settings.
tloadPrints a graphic representation of the system load average.
ttyPrint the filename of the terminal connected to standard input.
unamePrint system information, Prints Linux.
vmstatReport virtual memory statistics.
xcpustateDisplays CPU states (idle, nice, system, kernel) statistics. Runs in X?

Knowing what distribution you use would be helpful. If you need more help I'd recommend looking at the website of the distribution you use.
