Hi gho, Thanks for the answers
12) Safe mode worked well it went faster with no not responding issues. I was still picking up the noise in my speakers.
The above may be the key to this issue.... (we'll put the buzzing from the speakers on the back burner until we can get the Win XP stable and running reasonably well....)
Incidentally you are asking a lot of your computer to watch videos and the like when you have only 502Mb of RAM.... that amount was fine 5 or 10 years ago, but in 2012 with all the extra code your computer has to cope with..... its a bit like asking an 85 year old man to climb a few mountains in the Himalayas.... no wonder its beginning to puff a bit!
The significance of the computer working fine in safe mode with networking but not in normal mode is quite important..... In safe mode Windows only loads a minimal set of drivers (just enough to get the machine running but nothing more) so with these minimal set of drivers it works Ok but as soon as the whole range of normal mode drivers are loaded the problems occur.... We can deduce therefore that something that is loading in normal mode (but not in safe mode) maybe is causing the problems....so we need to zero on it if we can.
First step therefore is to:
1 Create a system restore Point and check that your back up is 100% accurate, comprehensive, reproducible and with at least one copy kept safe offsite on removable media (external USB hard drives are good for holding your back up copies) Make sure you have located your Win XP installation disc(s)and your 25 character(5 groups of 5) alpha numeric Win product serial key (as you may need them!)
2 visit the Dell site (the one I provided a link for previously) and download and install the chipset, video and audio drivers for your computer. (Do them in that order please with a reboot in between each one)
Now take a look here:Advanced startup options - XP
Use msconfig to determine what is causing the problemHow to use msconfig in Windows XP
Click on Start then Run, type msconfig and press Enter.
Click on the Startup tab, record what is currently starting then click the Disable All button.
Reboot and see if it runs better.
If yes then use msconfig to enable several items at a time till you find the culprit. (you will need to reboot each time so allow yourself plenyt of time for this procedure)
If no, start msconfig and click on the Services tab.
Check the Hide All Microsoft Services box, record what is currently starting then click the Disable All button.
Again, do a boot into normal mode, see if it runs OK
If yes then use msconfig to enable services till you find the culprit.
Once you've found the culprit, uninstall it or report back with your findings so we can advise the next steps(Simply disabling it in msconfig is a temporary fix at best.)
Enable everything else you disabled.
