Couple of messages on this issue from yourself and a chap called Paul that
I couldn't review because ...."News servers regularly expire articles as
they get older to make space available for newer articles" Looking at date
and time of both posts how they could be classified as old when they were
only posted 2 - 3 hours ago I don't know!. Anyway...................

Double checked for speaker. Definitely nothing that I can see or find.

I've removed processor chip and heatsink cleaned out dust from fan, heat
sink and mobo. cleaned off old thermal paste and renewed. Re-installed but
result on start is still the same.

Reviewed my notes on actions to date to see if I've missed anything in
diagnosis and to see if there is anything else I can look at.
****Interesting****

I said at start that original reported fault was problem with USB KB and
mouse not working. I used PS/2 KB and mouse when I started to look at PC.
On starting up there had obviously been a problem as I had repair or normal
start option waiting me.. I chose normal start, which it (eventually) did
and I was able to update and perform multiple restarts before turning off
for the night. This is the *****interesting**** bit. What I failed to
state when I restarted in the morning ..............I had removed PS/2 KB
and mouse and installed USB KB and mouse...............On start up, I
immediately got unrecoverable hardware error (0x0124). On restart, no
video, nothing!

I think whatever the (USB) problem was, the impact of using USB KB/mouse
was to take out the mobo. I really can't come up with any other answer. I
don't think there is anything else I can do; unless you know better, other
than inform my friend his PC is dead.

SC Tom,

No POST just blank from the moment it's turned on. No beep code sounds
at all but that may be because I can't see/find speaker anywhere in
(Packard Bell) case.

See all by reply to Bill re additional checks etc. I'm beginning to
think that mobo has gone AWOL. Would you agree ???


From the rest of your replies here, I'd be leaning that way, too. If
everything has been unplugged/removed, and there still are no beeps, it's
probably the mobo, power supply, or a bad connection between the two.

Odds are, there isn't an off-board speaker. Most have the speaker built
onto the mobo- look for a round black plastic piece about the diameter of
a dime. That would be your speaker.

Hi,

Received friends PC last night with a view to fixing for him. (Only)
reported fault was no (USB) KB or mouse (?), Mobo is Gigabyte
GA-K8NUSL-RG, AMD 64 Dual Core 4600+ processor, 2 x 1 GByte RAM. and
dual GCSLISW-RH graphics cards running in SLI mode. O/S is Windows 7
Ultimate

Connected PS/2 KB and mouse and on boot presented with DOS window
indicating error had occurred and whether I required to repair (via
CD) or start windows normally. Opted to start normally (why not) just
to see what happened. It got to Windows starting icon and hung for
some time and just as I was about to press reset it continued to
desktop after completing (earlier) update installs

Decided to remain with PS/2 configuration and check for further updates
to PC. Eventually completed all updates after a few hours work with
multiple restarts and restarted one last time to check all OK and then
switched off until this morning.

Started up this morning and promptly got unrecoverable hardware error
code 0x0124. Pressed restart and on reboot no video - nothing showing
on screen at all! That is still position

One suspect is Graphics because previously experienced starting delays
on another win 7 PC when booting, Turned out that despite win 7
compatibility testing, card wasn't in fact compatible. Similar time
lag on this PC. Also, there was an update for the card which, I'm now
regretting, I downloaded and installed. Didn't have problems using
last night with multiple restarts since installation of update. I
don't have a spare PCI express graphics card to try so stuck. Am I
barking up the wrong tree? Is there something or anything else I should
be looking at/trying. Help much appreciated.



Upon restart, did you get your POST screen, or is it just blank from the
moment it's turned on?

If you get the POST screen, then press F8 repeatedly and see if you can
start up in Safe Mode or Safe Mode with Command Prompt.
If you can get into Safe Mode, roll back the driver for the video card
through Device Manager.
If no Safe Mode, but you can get into Safe Mode with Command Prompt, you
can attempt to restore your system to an earlier time by typing in

%systemroot%\system32\restore\rstrui.exe (for Windows XP)
%systemroot%\system32\rstrui.exe (for Windows 7)

and pressing Enter (I know you said the OS is Win7, but this is an XP
group :-) ). The normal System Restore GUI will come up, and you can
then pick a time before the driver update was installed.

If you can't get into either mode, turn the PC off, pull the power cord,
open it up, and remove the video card. Plug it back in and turn it on.
You'll get a series of beeps, meaning that there is no video card
installed. Turn it back off, unplug it, and put the card back in. Turn
it on and see if you have video again. If so, roll back the video driver
as soon as you are able to navigate through Windows. (Of course, this
suggestion is moot if it's an onboard video chip.)
