Turned on computer-went to the screen that GIVES you the option to boot in safe mode - or last known .....(gives you 4 options) does the countdown to start in normal mode and then goes to black screen with white mouse icon only. Tried all the other options-Safe Mode etc. with no success. Have all the disks -M/S Windows xp Home OEM- Microsoft Works Suite 2004 OEM Norton Antivirus. My son was the last person to turn computer off the NIGHT before-he plays alot of games etc. Do not really know where to go from here-hopefully do not want to loose everything-Computer is Intel Pentium 4 630-3.00 Ghz - have a whole list of products on receipt when computer purchased-can provide more if requested. Maybe computer not turned off properly-or something downloaded that shouldn't have been ? Appreciate any suggestions. 1.

hi Broni - firstly thank you for your help - i am a total beginner -thank you
I am going well with your instructions (i do have my own cd) and now I am at the end bit where I have to decide if my CPU features Intel XD or AMD's NX (need to include NOEXECUTE if it does) I have been searching the web to try to find out if I do. I have a Intel Pentium 4 630 -3.00 Ghz [800FSB/LGA775/2MB Cache) Have you got any ideas how I can be sure ? I cant access any information on the computer as I cant boot it up. I dont really want to continue and just guess that I dont have these features.
Thanks Broni. SORRY I am a pain. DEB GYour CPU is an Intel. It is not an AMD. Quote
