Getting the start up screen but cant take the next step into the bios. Screen freezes up. Post Code 7F.
New system buildonly second system I have built)
E 6850
Zalman CNPS 9700 NT
EVGA 680i A1
XFX 8800 Ultra 650
Thermaltake 1000W modular
Corsair Dominator (2x1GB)(PC2 8500)
Western Digital Raptor X (150GBx2)
Lian Li PC-G70B (full tower)
Dell 2407 (from previous system-works perfect)
no floppy, no dvd drives, no sound card until i get it running
1) Put these components together, used AS5 on hsf.
video card in x16 slot closest to cpu
2 sticks memory in slots 0,1
all case connections in place
RESULT-back case fan not rotating,nothing on monitor,post code 25
2)
chose different mobo fan connector-RESULT-fan working
reseat video card- nothing on monitor, post code 25
clear cmos-nothing on monitor, post code 25
use second x16 slot-nothing on monitor, post code 25
3)
change build-
alternate video card (BFG Nvidia 7800 GT OC)in slot closest to cpu
reseat memory, only ONE stick in slot 0
no hard drives
reduced case connections to fans and front panel
RESULT-initial screen on monitor, freezes up/cannot enter bios, post code 7F
4)replaced BFG with XFX in same slot -RESULT-now achieve initial screen and post code 7F
5)
complete reinstall, including mobo,
reseat cpu, used Zalman thermal grease this time on hsf,
reseat memory
no drives attached
XFX in same slot - RESULT- post code 7F
6)
use other memory stick- RESULT -7F
Only thing left to do is build externally and test- never had to try this, what steps should I take?
Is this worth doing based on what I've already done?
Anyone have experience with this post code and this mobo?
Any input on build compatibility, other options, or a diagnosis is appreciated.
