hi all
and thanks for your response as usual very fast and useful.
Problem:
xp pro
amd athlon 1800(tm) h-series
512 mg ddr 2100
motherbord asus a7a266-E
at the moment had leadtek nvidia gforce 2 mx/mx400 64 ddr
(i did not follow the golden rule dont change nothing until is broken ) so i decided to change the card
i bought ati radeon 9200se 128 ddr gexcube (agp8x)

i follow instructions and when everything was done system rebooted i couldnt logg into the computer any more
it gave me a message-windows was unable to save all the data for the file c:|$mkt.
so i went back and use last working configuratuions.
tried few tings like uninstaling and instaling back same thing message same and sometimes you may have problem with your hardware or network connections.
so i took it out and put my old one back
when i instaled radeon card i was able to work even test her with aida 32 and drivers were there everythink was working ok.
once i shut down or reboot same thing happen.
my motherboor supports 2x and 4x agp but on the card its said it supports 4x and 8x so that should be fine or is not?

do i have to change something in bios?
i am very familiar with instalations and hardware as i am able to put pc togather from scratch-done it so many times
where to start from here?
just concerned not to damage motheboard.
thanks
