Stuck at Early PCI Initialization in POST

by ZeroWingAlpha / October 5, 2010 12:55 AM PDT

Hey everyone, I have a bit of trouble here. I just finished moving my hardware into a new case I am having a problem getting past POST. Here are the specs:

Motherboard: ABIT Fatality AN8 SLI
Videocard: NVIDIA GeForce 7800 GTX
Harddrive: Maxtor DiamondMax Plus 8 40GB ATA/133
2nd Harddrive: Seagate Momentus 5400.2 120GB SATA
Soundcard: SIIG SoundWave 5.1 PCI
RAM: OCZ EL DDR PC-3200 Dual Channel Platinum 1GB (two sticks)
CPU: AMD Athlon 64 X2 Dual Core Processor 4800+
I also had two 120mm LED Silent case fans that were replaced by two new 120mm LED Silent case fans that came with the new case. I also removed a CD Drive (but kept a DVD Drive) because there is not a necessity for it. All of these parts with preexistent in a fully functional and working computer prior to moving them to a new case.
The motherboard is equipped with a visual LED/POST code device that reads ?25? whenever I boot up my system. The manual describes POST code 25 as:

Early PCI Initialization
-Enumerate PCI Bus Number
-Assign memory & I/O resource
-Search for a valid VGA device & VGA BIOS, and put it into C000:0
Sometimes it will code ?9.0.? before 25. The manual describe POST code 9.0. as:
Complete uGuru initial process
AWARD BIOS take over booting job

I?m not using uGuru so this baffles me. I?m not a hardware guy and I?m at the extent of my knowledge. Obviously it?s a hardware issue however I?m fairly confident none of my hardware is damaged there for I must have connected something wrong, or made some type of mistake trying to boot it up after dismantling and rebuilding in a new case. Any advice is welcome. Thank you for your time.

Progress Update:

-Cleared CMOS, No improvement still coding 25
- Tried a minimal boot using just the following components: Motherboard, CPU, Power Supply, Single stick of ram, Videocard and Keyboard. Boot Successful.
-Tried to boot using all components except Hard drives Boot Successful.
-Tried to boot using all components except main hard drive. Boot Successful.
-Tried to boot using all components. Boot failed, coding 25.

Probable cause: Possible lose IDE cable. Solution: Checking main board and hard drive.

Probable cause: Bad IDE cable. Solution: Swapping IDE cables between the hard drive and the DVD drive.

Probable cause: Bad hard drive. Solution: None available.

Do you have any other thoughts? Any advice welcome. Thanks for your time.

While the old "extra standoff short on the back side of the motherboard" is now legendary, did you try setting up the machine on card board without a case for a test?

Bob ? I didn?t set it up on cardboard and test it prior to putting it into its new case. At this point in the trouble shooting should I continue to worry about my motherboard shorting out or have I eliminated that possibility? I haven?t seen any warning signs of a short.

Progress Update:

Switched IDE cables between hard drive and CD drive. Insured IDE cable was firmly and securely plugged into component and main board.

-Tried to boot using all components except main hard drive. Boot Successful.

IDE cable not bad.

-Tried to boot using all components. Boot Successful.

Initial issue was probably related to the IDE cable not being fully plugged in.

Disk read error. Rebooting system gave me POST code 9.0.

- Cleared CMOS and tried to boot using all
components. Boot Successful.

Disk read error. Unfortunately I only have a USB keyboard that will not allow me to Ctrl+Alt+Del after the Disk read error. I?ve solved the initial problem however, it seems as though I?ve come into another more major problem. Bad hard drive, or just failed to read? I don?t know how to tell the difference.

Well, I solved the problem, however BOOTMGR is missing. I guess I should've expected something else to go wrong. Now just to find that dang Windows CD...

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
