Title: Building new system; motherboard/BIOS problem?
Post by: rlsullivanjr on January 25, 2007, 07:18:42 AM

I'm building a new system and I cannot get it to boot. It gets through the POST phase ok (at least I get a beep), with or without the floppy and/or hard disk connected. It will freeze in a few different points, such as:

- Verifying DMI Pool Data
- In the BIOS editing screens
- On the BIOS splash screen

During the "Verifying DMI Pool Data" phase, I get the following displayed:
- +3.3V = 3.34V
- 12V = 11.71V
- CPU Vcore = 1.31V
- +5(V) = 5.34V

Configuration is:
-  Biostar P4M800 Motherboard
- Pentium D830 Dual Core Processor
- Power Up Doom 2535 case with 400W 20/24 pin power supply
- existing monitor, mouse, keyboard, hard drive and floppy drive that have been verified to work ok.

I have tried resetting CMOS multiple times. I also notice that if I wait awhile before rebooting, the boot process will progress a little further before hanging.

Any help would be appreciated.

Regards,
Bob

What is the boot order?  Is it trying to boot from harddisk, floppy or cd drive?  Have you tried booting it from the cd drive?

Unplug everything except the CPU/Fan, 1 stick RAM and onboard graphics (if you have it. Use the video card if not) and see if that will boot. You have too many variables to sort through at once. You need to simplify things to see where the problem truly is.

I can't determine the boot order. The system hangs in the bios screens before I can see it.

I have already tried booting it with the simplist configuration (no daughter boards; 0 or 1 stick of memory; with and without hard drives and floppy).

I also tried a different mouse, monitor, and keyboard; and reseating everything (even the cpu). No luck.

btw. It's now at the point that I don't even get a beep when it powers up.

Have you tried swapping in a known good PSU ? ?

Don't get a cheapo...you might wind up in the same situation in a few months.

Just tried another power supply. Didn't help. I'm going to try another mother board. I was planning to build a second system anyway, so it will just become my first system. What do people like for motherboards - socket 775, pentium dual core capable, either DDR or DDR2 memory (I have some of each)?

The first thing I suspected was my build procedure. I thought I had done it wrong. I was mistaken.
