    The graphics might not be good either which is why your getting no beeps and no activity. Are you using the onboard graphics?

  8. is it possible that my new memory can damaged my mobos?can u explain ,my pc is less than a year old?
  9. i remove then put back battery it started for awhile then it stops?what is wrong w my pc?
  10. You need to take the time to communicate more information and be more clear.

    1) Why did you change power supplies? How do you know the "new" one works?

    2) Put the old psu back (unless you are absolutely certain it is broken) and use one stick of your new 1GB memory, clear CMOS, load defaults, edit them and save. Then boot up. Tell us what happens.
  11. Maybe the RAM is set to AUTO for all the timings, and the sticks have different timings. This can cause boot up hangs. Clear the BIOS, as suggested by others, and manually set the RAM speed and timings to relatively high settings. Please list the actual model of all sticks of RAM, and we can give you some ideas to use for the timings.
