faulty vga damage mobo?

hi there,
recently I install a friend's vga (agp) that is he said not working anymore to see if its still working and found out to be true, but when I install back my vga its not working as well and install it again to another pc, same thing happen, the working vga when i install back its not working anymore,(very confusing, sorry for my english) to make it short my two working units destroyed by just testing a damaged vga, is it possible?

 

A problem with just taking a graphics adapter out of one computer and putting it into another one is that the drivers and software for the original adapter can get corrupted when those drivers/software try to run the new adapter.

If I want to test a different graphics adapter, I go to Add/Remove Programs and uninstall the previous adapter (drivers/software). Shut down, then replace the adapter. The new drivers then need to be installed, unless Windows has a basic set of drivers that can make it work.

You might be corrupting the drivers (more likely the software) if you just change the adapter without uninstalling previous ones first.

Look at the installation instructions for the adapter (adapters), it will say to uninstall any drivers or software for the previous adapter before you install the new one. Don't just take the graphics adapter out of one computer and put it into another computer.

jsctolitz, can you see anything at all on the screen like POST ? If you can, chances are that you only have to update the drivers as Matt said otherwise its a toast.

 

those are my old computers that is running ok before inserting that damaged video adapter,at first boot, windows able to open but the screen appears large pixels and then become black, when I reboot it just stay black dont even show the POST, just the same thing happen to the other one, mattman, I didnt had a change to uninstall the driver because windows did not load properly, those mobos dont have a built in video. all i have to know if the mobos could still be usable or if I bought new card that might damage again.

 

Looks like a broken graphics card to me. Can you test with another card ?

 

LOL, sorry RS and I'll may be admonished from admin for not adding anything to the thread but if you read from the start I'm pretty sure you'll hit yourself upside the face

 

Oops. Done it again. Thanks wildfire for pointing it out.

 

I did research on the system you have in your My System information, but you say they are older systems, you should include the details of the computer or at least the graphics adapter/s you are working on.

Admin's suggestion seems to apply, they could be the wrong voltage.

If you can't see the first POST screens, the only thing I know to do is "clear the CMOS ". A basic method to clear the CMOS is to disconnect any power, then take the motherboard battery out for a minute or more (you can also press the power-on button to drain any residual power).
