Monitor doen't display.

Is it due to RAM problem or Video Card prob?  My Auntie gave me their old Computer. When the computer arrived at Home, I switched it on and a long beep came up. IMy cousin told me I need to replace the ram with a higher one. The old RAM is DDR1 PC266 128mb. I bought two 512mb DDR PC2100 266Mghz. I installed it to the PC and  the Monitor does not display. I checked the monitor to other CPU, seemed to have no problem. What should I do? Buy a Video card?
         I don't know the specs of that Computer. but the mother board is Asrock. Please help me..

Try troubleshooting first by reinserting RAM and Video card and make sure they are firmly inserted. Make sure the mobo is free from dust/dirt. Check for any loose and suspicious faulty cables. Try flushing out the power by unplugging power cord and pressing power button for 5 to 10 secs. Make sure all fans are running in good condition when powering on and check for any burn or disformed capacitors(blue/black beer can like). Clear CMOS battery or better yet replaced it with a fresh one. OR If mobo has solder points for clearing CMOS and reset parameters to default setup, use a paper clip to short for 3 SECONDS. Anyway, you have not mention if the computer was working when it was given or has previous overheat problems.

Look up the model number of the Motherboard as well and get the specs. You might be trying to install 512 ram on a motherboard that will only take 256. I'm not saying it wont, I am just saying you really need to find out what the limitations are.
