Hi, I just got a new motherboard and cpu recently because my previous motherboard and cpu died. Here are my specs now:

Athlon 64 3000+
Windows XP Professional SP2
all driver updated
asus k8v-se deluxe motherboard
creative soundblaster audigy
1GB corsair memory (2x 512MB)
ATI 128MB Radeon 9800 pro
linksys wireless-G USB adapter

I'm having problems shutting my computer down fully. When I try to shut the computer down, it gets to a screen saying "It is now safe to turn off your computer". This screen comes after Windows saves the settings and stuff. So, when I get to this screen, I have to manually shut the computer down, which is annoying because I didn't have to do this with my previous setup. I googled this problem and still can't fix the problem. Please help...any help is great! Thx in advance!
