Hi I have an old 486 and earlier in the week I tried it to see if it worked I saw the processor digits on screen running and I went into CMOS but did nothing.
Now on boot-up it shows FO on post-test card.
I also get one long beep followed by two short, and one low buzz followed by one high buzz?
I have changed the graphics card but no joy.
There is nothing on the monitor at all now any ideas anyone.

Could be the RAM - and as it's an old 486 it might be a job getting some new memory that fits it.

Probabilitydrive, Hi yes helpfull thanks maybe both my vidio cards are bad
1 Long, 2 Short Video adapter failure = Bad video adapter.

The MOBO is a GA486AM/S and I cant find a reference to it.

it has 32 mb of ram that must have been expensive,
I have plenty of this type so will give it a try and remove some sticks and try one at a time.

Yooooooo Up and running bang on the nose (rodriguez) removed some ram and left one stick in.

Thanks for your help everyone.
