[SOLVED] Tried dual display card, none works now!!

I have a P III 550 MHz machine with 128MB RAM, Win98SE. Motherboard is Intel Based 810 with on-board sound and display.

On board display was working just okay. But my machine used to hang at times. So the first doubt was on the display going defunct. 2 days ago, I got another display card installed and disconnected the on-board display. Even that worked fine.

But I got greedy and wanted to try dual monitors in Win98SE. So the engineer activated even on-board display. I don't know what went wrong, but now none of the display bay works. I connected my monitor at each of the places, but there is no display. Monitor is new and working perfectly well even on other machines.

I removed the battery of the motherboard and kept it without the battery for some time (5 mins.). But that didn't help. I even disconnected the other display card, but still display is adamant on not coming up. A small indicator light on the monitor just keeps blinking. The monitor is a 17" Samsung and is not even a year old. My machine gives me the usual beep and so there is no other problem.

Since display is not working, I can't even check whats wrong in BIOS settings

How do I get my display back?

 

physically remove the new card and enable the onboard.


what happens?

 

I have tried that. It didn't work.

 

What did you attempt to install for a second video card? Make, model and slot type(AGP, PCI)

 

My problem is solved by restoring BIOS defaults. "F" key was kept pressed during boot up and it solved it.

Many thanks to Jtoast and Rockn for trying to help me.
