When my computer started i can't see anything good.
First i have on beep codes 1 time
Second monitor show my diferent colors lines from up to down.
(windows now is not startet it is DOS). If i do nothing windows get started, but screen will be with lines. Monitor works good. i think it is aproblem with BIOS. Shared memory which must be 16Mb but now (?).
How can i reset BIOS in very old compiuter about 1999 and repair if i can't see anything.

Hi and welcome to D-A-L

do you know what machine make, model No, or motherboard make?

sometimes removing the battery may reset it

Sory i am first time here
But i dont know about this compiuter nothing,
just CPU is 850Mhz, hdd 20Gb it is old compiuter and dont have a number on the motherboard.
On the bios chip writing AMIBIOS 686 1999 AY82 9505
on the motherborad is label TM-A1631LM
Just it
I reinstall the windows work good (windows xp)
But now i see more litle simbols like lines from up to down.
Maby you have ideas?

o forgot removing battery not work.

how much RAM have you got?

all I can find on the motherboard is this http://ertsims.netfirms.com/tm-a1631lm.htm

This is not a true motherboard
Maiby you now where i can find drivers for this mother board?

i have 512Mb RAM
on BIOS i can change shared memory.
Was 16Mb, but now i thing non
and my integrated videocard work crazy.
How i can change shared memory if i can't see?
Maby put new video card in slot, change bios and removed video card from slot. But i dont know how tow video cards works in one computer together, in old computer there no swichers for video on the motherboards.
