    is it possible for both ram cards to go out at the same time?

    ANS: Possible but not likely.

    Did you clear CMOS?

    Take all boards out of the unit, leave. Then restart and see what happens.

    BTW, Never force the Ram into the banks. they should snap in easily!

    The pin header should be labeled "CMOS clear"

    I could not find a diagram of your PC. But I found the service manual. Look at the section under "Battery".

    With the power off and power cable disconnected:

    Take the battery out per instructions, them take a screwdriver and short the two metal tabs for about 10 seconds. Put the battery back in and power up the PC. It should start ok, that is unless something happened to the motherboard when you switched Ram.

    Look at the CMOS battery (size of a quarter), near it you should see a jumper to clear CMOS. move the jumper from the pins it is on to the 2 outer pins. Keep it there for 30 seconds, then put the jumper back on the original pins. This will clear CMOS then make sure your original Ram is seated correctly before you turn the PC back on.

    Let me know if this corrects the issue.

You may have fried the original RAM by using improper installation techniques (no static provisions) or you may simply not be seating the modules properly, it take more force to put them back than you might realize. RAM is very specific to proper fit (voltages, etc.) Freebie RAM is rarely free.

Check the Diagnostic LEDs on the system, see if they give you an indication.

If you still cannot ID anything, I'd try a replacement power supply 1st as that is about the least expensive item

Does your computer completely load up after getting the prompt?
You have to make sure that your ram is all the same. If it is a custom computer and you bought the different parts, your ram cards could be different, the motherboard for your computer requires a certain ram cards. All are different so i wouldn't be able to tell you which one your computer needs. You would have to find the one that works and see which it is ex. PC 100, PC 3100 etc.
and if thats not the problem then either the card slots in your motherboard could be bad or just the cards could be bad.
