Christmas day, yay. Hi all, i hope someone can help me as i bought a customer returned dell dimension xps 720. It has no operating system with it so i tried to load it. After setting boot device i put the windows xp pro disc in and it starts the cycle. It gets as far as windows is starting and then blue screen saying it shut down as not to cause damage. 0x0000007b at the beginning of stop code. I tried another hdd with windows on it from another xps pc and gets as far as the windows black bit , about 5 seconds and it reboots. I took all the memory out and installed 1 at a time in case it was a faulty stick. The bios sees both cd devices and the hdd and everything looks normal. I am not a technician but have been able to sort out many problems over the years but not this one. I have never had a pc desktop that just had sata stuff, just ide. Please take pity on me for not being able to afford a new pc.And not knowing what the hell i am doing. Thanks in advance.
