[KKK]

i assembled a new system with the following
athlon 64 3200+
ASUS A8N-E mobo
XFX GeForce 6600GT 256MB PCIe
2x160GB Seagate Barracuda 7200.9 SATA 1 HDDs
2x512MB Transcend Jet RAM modules (2.5,3,3)
VIP 400W PSU

my problem is that the even after checking and rechecking the connections....the PC does not

boot up...it starts but there is no startup beep!!!
also if i try to switch it off by pressing the Power Button for four seconds...only the

Power LED goes off and the rest of the system is on...and thats where i loose control of the

system because the only way then to switch off the system is to cut off mains power!!
PLZ HELP!!!!
