Vista - Vista Won't POST or Boot After BIOS Mod

Vista 32 is installed on my year-old homebuilt computer (Gigabyte P35T-DQ6 m/b, Award BIOS V6.00PG, Intel E6750 cpu). It's been working just great. At the end of a normal computing session, I entered the BIOS to make a small change. When I attempted to restart, the POST stalled after running the memory check.

In an attempt to correct the problem, I reentered the BIOS and removed the several changes I had made and, I think, returned the BIOS to its former configuration. However, the result is the same; it stalls after the memory check. The rest of the POST does not run. It never gets to the point where VISTA should boot.

Since then I have cleared the cleared the CMOS several times by shorting the CLR_CMOS (Clearing CMOS Jumper) (Page 34 in the m/b User's Manual) and reentered the configuation, loaded "Load Fail-Safe Defaults", loaded "Load Optimized Defaults", and again reconfigured from scratch. None of these attempts have enabled complete POST nor O/S boot.

I'm out of ideas. Your suggestions are solicited.

Start with knowledge:

1) Vista never POSTS (Power-On Self-Test)
2) Vista never does this because Vista never sees the BIOS as it POSTs
3) POST is a purely hardware-only test from the level of the machine
(the lowest level). Vista has no part in the POST.
4) Normally, what is happening is supposed to happen when something
goes wrong while you were updating the BIOS.
5) Either you used the wrong BIOS update, or you applied it
incorrectly, or you may have lost power during the BIOS flash.

Be prepared for any of these:
a) a motherboard which is now a paperweight (worst case)
b) dead CPU
c) useless BIOS chip, replacement is only recourse
d) As machine begins POST, strike special key to enter BIOS setup
program. ON Award BIOS motherboards, <Delete> will enter the BIOS
setup program or <F12> will give you the Boot menu, one choice of
which will be to enter BIOS setup program.

This wasn't caused by flashing the BIOS. The OP entered the BIOS
normally and made some changes which turned out to be disastrous.
Supposedly undid all those changes, but apparently missed something.

I see nothing in your long-winded post that applies.

What was that "small change"?
Now that "small change" has become "several changes". It is apparent
that you didn't undo everything you changed the first time you entered
- or you're not telling the whole story.
Something is missing here. Setting the BIOS to defaults should have
fixed most any problem. Do you have any special disk setup that
requires tinkering with the BIOS defaults, like RAID?

Did you physically enter the computer to do anything before you
cleared the CMOS?

Confirm (in the bios) that your HD is actually listed as a boot device

For example, your mobo my default to ATA and you have an SATA drive

or visa versa

I have checked and/or reseated as suggested and all seems be be ok.

From another computer, download the latest BIOS for your computer MOBO and
install in the manner that your mfg suggests. USB, floppy, etc.
With any luck you only had some sort of power problem that messed up your
current BIOS The point you mention would be where the drives are scanned.
You could try unplugging your drives, HD and CD and see if it gets past that
step. Sounds like you have some sort of hardware problem at this point.

In fact, it sounds as if the BIOS doesn't see any hard drive(s) at
all.

The OP would know that by checking the main screen after entering. If
it's an older board, re-checking (set on AUTO) might fix it.

Philo,

Yes, the boot order is floppy, DVD-ROM, and then hard drive.

P.S. Currently, I cannot enter the BIOS. The POST hangs after completing memory testing with this message:

"Memory Testing : 4193216K OK
Memory Runs at Dual Channel Interleaved"
