Hi,

Try powering off, disconnect the power cord from the wall, then remove the
cmos battery from the motherboard. This will remove any memory of changes
that may be being held by a trickle of power (clearing cmos via jumper
should work, but sometimes things don't do what they're supposed to). Wait
20 minutes, then reinstall the battery, reconnect power and start up. It
should load factory defaults.

If the above fails to get through the POST, you should assume that a
component has failed. It may or may not be related to the changes you made.
It could be merely coincidental. I would check the manual to see if it has
any motherboard diagnostic steps, and possibly check the power supply.

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.

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"

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.

Please reply to original thread
============================

Donald,

Thanks for your response.

I was careless in composing the title of the thread. It would have been
more accurate had I said, "After changing BIOS settings, computer will
not POST; VISTA 32 does not boot."

I did not attempt to update the BIOS to a new version, but only to
change a couple of settings. In retrospect, I should have adhered to the
adage, "If it ain't broke, don't fix it."

This might look dumb at first glance, but are you sure that your
keyboard is working?

When building the machine about a year ago, I had intended to have a
RAID1 configuration. However, I was unsuccessful (this was my first
build) and decided to forgo the RAID in favor of a simple one SATA drive
configuration. When I entered the BIOS intending to shorten the POST
procedure, I discovered that RAID was still noted as an active
configuration. However, there is only 1 hard drive, a SATA drive, in this
machine.

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

No, I did not. However, since the problem arose, I have opened the machine,
ensured the cards, cables and memory were well seated. By the way, all fans,
including the CPU fan, are working normally. On each restart / cold start
attempt, the computer does complete successfully the Memory Testing. Then it
hangs. I have been unable to reenter the BIOS setup.

As someone else suggested, I did disconnect the floppy disk and SATA drive
power and data cables. But, there was no change. The computer still hangs as
described above.

I also wondered if the keyboard was really working, so I swapped
keyboards (both ps2 wired). I'm sure it is not the keyboard.

re-read my post please
your response has nothing to do with what I mentioned

Did you change that setting??? You probably shouldn't have.

As to your not being able to enter the BIOS. Clear the CMOS again.
Doesn't that result in the computer automatically opening it up so you
can change settings?

As for your keyboard being OK... what if you screwed up a serial port
setting while you were in there playing around?

I surely hope you've learned something by all of this.

If you can't download and replace your BIOS, the odds are something happened
while you were saving your changes that harmed your BIOS chip. You should
contact the mfg of your board mfg if this is the case. You will find
hundreds of similar cases in the discussion groups for the boards requiring
an RMA of the board . At this point it is not a Vista group issue. Good
luck. Gigabyet/Asus is good at diagnosing the problem on the phone and
emails.

All,

Believe it or not, my computer is now working!

Today I decided to try shorting the CMOS one more time. I did, then
restarted the computer. Lo and behold, the machine POSTed and booted.

At someone's suggestion, I had previously disconnected the hard drive
and the A: drive, then restarted without success. It was after that,
that I reattached the hard drive, but left the A: disconnected and
shorted the CMOS. Then restarted with success.

Wish I knew which action or actions enabled the POST & boot to be
successful. But, I do not. But, it is working!!

Thank you all for your suggestions.
