Wierd Post Problem

[rms78]

Hiya folks...
Got a few newbie qns :

1) i have another mobo which has a problem.. the mobo keeps thinking that the keyboard is connected even when i remove the keyboard plug.. once it does the POST test, there is one long beep but i am not able to type or do anything once i plug it in.. the NUM light is not turned on.. I have tried the keyboard on other computers and it works fine...
Possible solutions or causes ????

2)Due to the fisrt problem... i have just changed my mobo to a ABit KT7 and i got this weird problem.. the first time i start my computer, everything starts out fine.. changed my CPU speed at the CMOS and as i was going thru the CMOS settings, i saw a option like "Monitor CPU temperature :confused: " thingy and i saved and exit. Then there were beeps going around so i shut it down and clear the BIOS by the jumpers..
Now all of a sudden, the computer doesn't do POST.. it just "hangs"... The hard disk runs & fan runs but there is no Beep...I have to power down my computer, turn off the power box switch(my powerbox has a switch behind)... and then turn on the power box switch and then press the power-on button on the casing... sometimes it works, sometimes it doesn't ....

I was reading thru some of the answers and i realised that i didn't wait for half an hr for the CMOS to totally clear.. i will do that once i get hm but what could the other cause be ???

I am starting to suspect that the shop did not fully repair this mobo... bcos it fried b4... :mad: .. not sure if tat could be the case...

Thanks for ur help...

Welcome to http://www.pcguide.com/ubb/pcgubb.gif

I am not sure I have the details here. Are both problems on the same mobo? If you are getting a long beep, have you looked up your BIOS beep codes to see what that means? If you haven't, it would probably be a good place to start.

For the second issue, make sure that you put the CMOS clear jumper back on properly. If that is ok, I would check all other connections and make sure nothing has come loose as you have been working with the system.

One more thing, if you board actually fried, the possibility of fixing it without having more problems in the future are small and you may be better off buying a new board (probably cost less than the repair anyway)....

thanks Budfred..
first, problem 1 belongs to a gigabyte mobo... and problem 2 belongs to a Abit mobo...
i will go back and check right after work... ARRRGGHHH !!! why does time pass so slowly..... :mad:

Concerning the first motherboard....
i have another mobo which has a problem.. the mobo keeps thinking that the keyboard is connected even when i remove the keyboard plug.. once it does the POST test, there is one long beep but i am not able to type or do anything once i plug it in..

You probably already know this so forgive me, but can I assume you are hooking up this keyboard via the USB port?

If through the ps2, keep in mind that you should never hook it up with the computer powered on. (If I am reading your quote correctly) :)

nah.. i am hooking up my keyboard via PS2 port.. Funny thing is that once i shut down and unplug the keyboard.. The computer still continues processing till Windows... The Bios/CMOS doesn't detect the missing keyboard which usually happens.. And when i put it back(after shutting down :D ) and power up the computer.. the keyboard doesn't work and no matter how i bang on the DEL key, it doesn't go into BIOS..
i was wondering if an USB keyboard would work properly ? don't want to waste any unnecessary money ... :cool:

[Budfred]

A USB keyboard might work, but you will need to make sure your BIOS supports it and you probably need to get into BIOS to do this. Catch 22. Another option would be to try a PCI card with PS/2 ports to see if that works, but they are hard to find and may not solve your problem.

After reading through your post I'm not quite sure if you addressed jabar's concern regarding the plugging and unplugging of your PS/2 keyboard while your system is running...

Are you powering down completely before plugging or unplugging the keyboard? "Hot Swapping" PS/2 devices can fry the connection! :(

Thanks for all your help..
i finally managed to figure out what was wrong with the ABit KT7 mobo.. it was the CPU processor speed setting.. i followed the instructions by putting it to the lowest spd which was 500 and i didn't turn it back to the orginal speed(1Ghz)..
funny how the little things can make u go bonkers.. :mad:

i gave up hope on the keyboard thingy.. i believe that the PS2 keyboard port has died... not sure how it did that.. but just a qn, can ur port be fried by just leaving ur computer on ? my keyboard port gave problems when my bro typed half-way, went down for dinner.. about half an hr later, he couldn't type anything... extremely weird.. case for the X-files ? :p

Your PS/2 port shouldn't go bad just sitting there, but it might if you plug it in and/or unplug it hot... If you can RMA the Abit board, that may be your best choice, but otherwise, there are PS/2 adapter cards you can get to substitute for the one on the board or you can see if your system will accept a USB keyboard...
