Hi I have a customers desktop - its ports suddenly stopped working
PS2 Mouse & Keyboard are not detected
I tried USB mouse and keyboard - but usb ports appear dead -  memory sticks not detected , no light on mouse, keyboards  etc
I pulled the bios battery to reset and now it says "checksum default loaded press F1", but when i pres F1 nothing happens cause the keyboard is not detected
before i removed the bios battery it actually booted up to xp with no errors , but could do anything as no keyboard or mouse. did not detect usb hardware plugged into it
Case was not unplugged or moved before this problem occured
I also noticed sometimes the power button needs a couple of presses to get going - not sure if this is related
This is weird , please help!

We could use some system details, but for starters:
Check the caps on the mobo and the psu

note that bad caps can be in the PSU also !
anyway here my recepy :
i suggest testing with the minimum setup - disconnect also all peripherals and network cables :
motherboard + cpu + 1 ram stick, video card, power supply
on boot, do you have a display?
if NO it is one of the connected, swap ram, Power supply, video card - leaving only motherboard and cpu
if Yes, add devices till the problem shows

Hi nobus , correct me if i am wrong , but your comments only related to getting the pc to post and in your words 'have a display'
From my initial description ' it actually booted up to xp with no errors', you can easily infer that the computer is already posting and already has a display
testing with the minimum setup is an obvious step even for beginners
Nowhere in your post do you suggest that the mainboard could be the problem. I was hoping someone could suggest something beyond the basic and obvious motherboard fault
I appreciate your help and contribution, and am happy to award you the points if you can tell me how your answer helped me solve my problem and told me something i didn't know?
Also, what is a 'recepy' - this word is not in the dictionary

well - im not native english speaking, so there may be errors in my wording; but how well do you speak or write dutch, or french - lol - not meaning anything serious...should be recipe, yes?
but if you feel my comment was not worth a reward; so be it...i only thought your problem should show IF you followed the "recipe"
