Since May 2003, during the one-year warranty period, my Asus reseller had to replace my A7n8x Deluxe motherboard twice since the keyboard and mouse (ps/2) ports were not working. Even with a usb keyboard plugged in, the machine seems to think a faulty PS/2 keyboard IS in (when it isn't) and hence doesn't sem to bother recognizing the USB keyboard. In May 2004, just before the end of my warranty, it happenned again (unfortauntely I couldnt take this for repairs in time, due to a critical illness of a relative). SO now my A7n8x does not work.
In the cases where they replaced my mboard, they did NOT know what the fault was. They just replaced it.
I strongly suspect that either the A7n8x itself, or the NVidia chipset that it uses, has some PS/2 related flaw. Any ideas anyone?
During bootup, sometimes the keyboard works for a WHILE, enough tiem to go into Bios and make sire thatUSB keyboard/mouse IS enabled. I have tried disabling those as well. In every case, suddenly control of the keyboard is lost. Once the OS actually booted, but my the the time the login prompt came, i had lost the keyboard control, and couldnt do anything; the computer power switch fortunately was wired to shutdown windows gracefully.
Everytime this problem came, I did notice that first for a few days the ps/2 mouse would start behaving erratically in windows; then the keyboard too. Eventually, they seemed to go completely. The same keyboard and mouse works fine in other machines; and other keyboards and mice do NOT work on this machine. It is very clearly a motherboard problem, and very clearly NOT an OS problem because even before the OS starts, just during POST testing for example, the keyboard control is lost.
Sometimes without ANY keyboard plugged in, I STILL hear a CLICK CLICK CLICK noise when the machine starts, like just before or during or just after POST.
(This is the first time in almost 10 years of assembling my own machines, that I've had such a headache. My two ABit LX6 and BP6 boards are FINE - LX6 is 7 years old and doing wonderfully. I didn't expect problems with Asus sinec i rank them with ABit.)
Am desparate for a solution! Couln't find anything on ASUS site.

Same problem here in a different mode
I am so maaaaad 35 $ extra instead of the fabulous abit nfs2.0 deluxe ( which died in fault of a bad memorz stick and i couldnt get on the weekend i need my pc the most..)
here we go...we boot up :
then:
NO KEYboard.. im like wth ?
then you unplug and backplug the keyboard and the power goes on..now we need a soft reset and keyboard recognized....
as soon as you shut the machine down bumm
same crap all over again..
so every time you have to crawl under the table unplug plug... its a nightmare
since 5 years i avoided asus mobos since hte bad quality reviews now im stuck with 35 $ more expensive non working board..hooray.. |

Yep me too.
In on year I have gone throw 4 PS/2 Keyboards due to either the board burning them out or it just dislikes them. Had to change to USB K/B & mouse. 4 months down the line and it's trying it's very best to distory that as well.
When this happens during POST I have random 'clicks' from the motherboard built in speaker. This causes the system to working untill I can replace the keyboard(yes I know I can turn the errors off or F1).
Could of been a lovely board. sigh :-( |
