Blå skærm ved install af XP

AGP - (accelerated [advanced] graphics port)
PCI (peripheral component interconnect)

sry, forkert spg :-/

Slet den gamle partition, og opret en ny, du kan også prøve med en anden ramblok.

When booting up to Win XP you may get a error that reads "Unmountable Boot Volume". This is probably because your boot.ini file is messed up.
    So, what do you do about it, panic and try to mount your boot in your computer...... No that is probably not a good idea.

    You can boot to the XP cd and when you see the Welcome to setup press the letter R
You will get a dos prompt
Then type "chkdsk  /p" without the quotes and hit enter
When that is done type "fixboot" and hit enter
"Y" and enter at the prompt
Then type "exit" and hit enter
The system will now reboot into Windows   

    If for some reason that don't work for you, you can boot to the recovery console like above and...
Type "chkdsk  /r" then enter
When done type "exit" and hit enter.
This will take longer, but the system should boot back into Windows.

måske er det dine ram der er defekte

Ved unmountable boot... plejer det ikke at være rammene, men harddisken der er problemet. Enten hardware eller software.
Gætter på det er bootloaderen den er gal med. Men kan også være andet.
Er det en ata100/133 harddisk, og bruger du et ata100/133 kabel?
