Computer shuts down automatically when it starts to load OS... can anyone fix this problem out...

How do you shut down? With the windows start menu shut down process? Or push the on/off button on the computer? Take a look at this: http://www.winhelponline.com/blog/fix-desktop-icons-layout-not-saved-restart/

I would start with a RAM check and hard drive test before I did much else. Errors while installing windows would seem to indicate a hardware problem of some kind.

Normally installing the os on a different mechine, and then putting into another pc dosent work.

If the hardrive is the oringinal drive, which came with the system, and you want to install xp on, you will have to use a dos disk with fdisk on it, delete all partitions on the drive and create a new partition, then start loading windows, it will give you the option to format the drive for nt(ntfs) file system and setup windows.

If you do that and it still gives you protecting files error, you will have to take the side panel of the computer tower, unplug from the mains and take the cmos battery out for about 30 secs, put the battery back in, plug in the mains and reboot the computer, start loading windows again
Hope this helps and post back if you need further assistance.

look for Win vista CD and boot your computer with it, then restore your computer back to a date that it worked perfectly, you won't loose any of your saved document or if you don't have a bootable CD, then at startup press F8 then select SAFE MODE and then at window, click on START-PROGRAM-ACESSORIES-SYSTEM TOOLS-SYSTEM RESTORE. Good luck

when windows starts up it loads my files. but when its loading files. it cant load those files, so its stop working and shut down. if u r not expert. reload yor cop of windows.

Did you try using Safe Mode? Hit F8 when its booting and choose safe mode. See if that will let you boot into the OS.

I have the 6100 sm-m and was having same problem .. I went to ecs website and flashed to old bios then downloaded new bios ... when updating make sure you check the bootblock , dmi, and hole .. I also checked the update all ... seems to have fixed the loading of vista and has not shut off

This sounds like a hardware fault with the motherboard. I would suggest you resseting your BIOS to default settings. Do you know how to do that? Please advise...

do a virus scan
can you get on in safemode

There is a compatibility update from Microsoft for Vista and Outlook 2003:

It doesn't address specific problems there, but it tells you how to get the compatibility updates. Sounds like a good place to start.
