Random black screen

[Guest]

So, i have just installed Windows Vista, dual booting with XP. Created a
primary partition on my 160. Vista installed flawlessly, except for sound
card drivers, fixed that immediately. Now, in the device manager, every
single device is working properly. Installed the latest ATI drivers. Computer
runs perfect. Except every once in a while, totally random, as I have not
found that it only happens when I'm doing something similar, my screen just
goes black, i receive a "No Signal Input" from my monitor, and I am forced to
hard shut down my computer. When it happened when i was watching a divx
video, the screen went blank, i heard sound for 5 more seconds, and then
everything locked up. Upon restart, the error was "BlueScreened"...Typical
windows. Can anyone help!?!

Asus K8VX-SE
AMD Athlon 64 3700+
1GB OCZ
Western Digital 160 SATA
ATI Radeon AIW x800XT

[When installing XP fresh, I always had to install VIA 4in1 drivers and
motherboard drivers like USB/onboard sound. Do i have to install those too
considering they're already installed on the other copy of XP? Usually there
would be problems with USB and onboard sound card if I had to install them,
but USB and onboard sound works fine]
