DELL Desktop problem

[peire]

ok i have just been given a dell desktop by my partners sister as she was just going to bin it so i said i would have it to see if i can fix it...

so the problem is it needs a good clean inside the tower as its full of dust, so i connect it all up and boot the tower and monitor up and i see on the monitor the dell startup logo then it goes off quick and i can see the faded loading bar then i dont see anything just black screen, and the tower shuts itself off and back on again a few times and then just shuts off completely so any advice on getting this fixed would be great

thanks

moddel of desktop: DELL VOSTRO220 running windows vista

the tower iv just cleaned out, never seen so much dust in my life lol its sound smooth when running now as all the fans have been taken out and cleaned and even the power supply as that had quite a bit of dust in i.

havent got another monitor to test with, was trying to find a way to use my laptop on the monitor i will re install windows once i can get it up and running..

Have you tried booting into safe mode?

Trying another monitor will let you know if the display problems are monitor-related. If not look inside the case to see if there is a video card which might need to be reinstalled. You'll need to get the display working to troubleshoot or reinstall the OS, of course.

You'll likely want to test the RAM and HD first to see if they're causing problems.
