   RAM Problem...
  I have just ordered a RAM card of 1gb (DDR). I received it today and installed it in my computer beside my other two 256mb cards. I turned on my computer and it's internal speaker emitted a beeping noise and it wouldn't start. Any Idea as to why this happens.Thanks in advance for solutions to this problem,Francis...

Any Idea as to why this happens.Thanks in advance for solutions to this problem,Francis...well, there could be a bunch of things wrong here.are you sure you got the correct speed of ram? some systems don't like lower or higher speeds of ram. secondly, you're mixing ram sticks, 2 and your new one probably made with different ram chips, different timings, and perhaps different voltage needs. this will create conflicts within the system since one stick may be taking priority over the system settings needed for it to run which may cause the other not to run. and lastly, some mobo's (motherboards) just tend to be picky and may require playing around with to get it to work, try switching slots and see which may work, if any.hope that helps.   ;  I'd put money down on your mobo not liking the fact that you aren't running paired sticks of RAM. In order to get actual dual-channel performance from DDR RAM you need to pair them, so if you want 1GB of RAM you should have actually bought two 512MB sticks.Still, I would think the mobo would still boot, just refuse to recognize the additional stick of RAM, so Jarrod might be on the right track as well. Regardless, you should be using two sticks, not one.Oh yea, and that beeping noise? That's a POST test. Go to this site to find out what your PC is trying to tell you   ;  since it hasn't been mentioned yet...i picked up another pair of 512mb sticks somewhat recently and although they were the same brand and item/model number, the new ones were single-sided instead of double. my mobo refused to post with any combination of 2-4 of my sticks until after i put them all back in and reset the bios.
