I decided to buy a new case from Dabs.com and transferred all my equipment over. I also bought a new sound card. After connecting everything i turned it on and there was just a blank screen until the windows XP screen loaded up which had lots of white lines obscuring the screen. I tried a different monitor that unlike my regular monitor did not have a DVI connection, whilst i could see the DOS information on start-up the screen still had the white lines across it but in a different pattern. I then reverted back to my regular monitor and checked the device manager. For some reason my graphics card appeared twice which i do not remember seeing before. I uninstalled one of the entries but this did not change anything apart from altering the pattern of the white lines. The next step i took was to uninstall both entries, again the pattern of the white lines changed on reset but windows detected the graphics card twice. I then re-installed all the graphics card drivers and the VIA 4 in 1 drivers (for the AGP) but upon start-up i couldn't see anything at all, not even the windows screen but there is hard disk activity.
I think my next step is to try to use the on-board graphics (motherboard) with a different monitor and i was thinking of doing a system restore. I have checked all the power connections and made sure that everything is slotted in correctly. The only thing that i can think of that has changed is going from a 300 watt power supply in my old case to a 520 watt power supply in my new one but as the distortion on screen isn't constant i don't think i have damaged my graphics card.
I would greatly appreciate any help.

Windows XP Pro sp2
