Thankyou Weedougie,this is the latest update of this bl#$%@ computer.
I put in a new floppy drive.then started to format a floppy.It got about half way through and then the computer locked up.I pressed the restart button and it started and got to the moving blue dots. then a black screen and then went back to restart..I tried several things and it behaved exactly the same. getting to the moving blue dots, black screen and then restarting I changed (in bios) starting CD first and put in the master XP CD (I thought I might try to do a XP repair) and it then stopped on the screen where you are to start from CD I pressed enter and it just ignored that and went on to blue dots (WIN logo) then back to restart.
I replaced the Power supply with the one from my main computer, Still the same.
Tested the original power supply from this computer (a 400 watt) and all tested OK.Took off the 80gig harddrive( 4months old) and put it on main computer as a slave and did a check.
It can up with a cycling redundacy error(whatever that means) .I then checked the harddrive thoroughly and auto fixed errors and defragged it. It was a mess.
Then backed the whole hard-drive into a external sata harddrive.Put the harddrive back on this computer and all is working very smoothly now. The Floppy drive is formatting normally and the computer is quicker starting (about 37 seconds.)
The slowest part of starting is loading in Zone alarm which it does second to last. Last is the Linksys drivers for the pci wireless card.Crossing my fingers and toes, the computer is now going well.
I have one more test to do.
Tonight just before I go to bed I will disconnect the case and seal it up in a plastic bag and put it in the fridge overnight to see if the cold has any detremental affect on it.I want to thank you all for taking the time to read my threads and offer helpful suggestions.
I hope I can do the same for someone on the forum in the near future.regards from Eliza.
