Computer takes forever to start up

I got my computer about a year ago from my mom's friend, so it's a used laptop with many things already on it that i do not understand.
But recently my computer is taking longer and longer to start up each time i boot it. Now it takes about 10-15 minutes to start up.
I tried running check Disk, i tried to defrag my drives, and i tried deleting every application and software i didn't need. But still i can't get the computer t start up quicker.
I don't know if it will help but ill post my system specs, and maybe someone will have some idea of what is wrong with my computer.

OS name- Windows XP Home Edition

I know this is probably more information than needed but if it can help, then why not.
I hope someone can help.
 
First I would see how long it takes to boot into safe mode. Use the F8 key to enter selective start up and choose Safe Mode out of the options.

Post back with the result.
 
OK, as soon as you press the power button to turn the PC on start tapping the F8 key, this has to be done before the Windows logo appears. You should then arrive at a screen that gives a few choices. Use the arrow keys on your keyboard to select Safe Mode and hit the Enter key. Then see how long it takes to get to the Desktop screen.
 
OK, run through these clean up utilities and see if there is any improvement.

Download and run ATF Cleaner follow the instructions on the page.

If there is still no improvement follow this guide.

CLEAN BOOT TROUBLESHOOTING technique XP

First, restart in Safe Mode (tap the f8 key promptly on startup and choose the Safe Mode option from the boot menu).

In Safe Mode –

Click Start and then Run, type msconfig into the Run box and hit Enter. Select the "Services" tab. Check "Hide Microsoft Services" and then disable the rest. Also uncheck "load startup group" on the general page.

See this link for detailed information:

Now restart and test the issue at hand

If no problems, run msconfig again and recheck half the disabled items on the Services tab. Test again. If the problem recurs, UNcheck half the items you just checked to narrow down the culprit.

If the problem didn't occur, check the other half, so all the Services are enabled -- proceed to do this on the startup tab as well.

Get the idea? You want to isolate the problem to a specific startup if possible.

Note: if you already have items unchecked under msconfig > startups and are in “selective” startup mode – you should note what these are before beginning. They will need to be de-selected again.
