    no ram can cause beeps. that's why i wanted you to put them back in. how many ram sticks do you have?

    Why? Because the beeps refer to the fact that there is no memory installed.

    It is very important when you do these diagnostic tests to follow the instructions carefully. Otherwise, what's the point?

    You stripped everything down to just the motherboard and CPU and restarted the computer. You got beeping telling you that the motherboard is working and looking for missing RAM. But the problem you are testing for remains.
    The test is done.

    You have isolated the problem to 3 parts: The Motherboard, the CPU, and the Power Supply. And as I posted in post #2, if I were going to guess I would guess the Power Supply. Sounded like it then. Sure sounds like it now.

    the instructions may be wrong or not include "no ram" beeps. take one out, leave one in slot one. switch them around and see what the results are..

    and to just make absolutely sure, you unplugged the motherboard, took the bios battery out, and shorted out the jumper correct?

    He may be correct, but it wouldn't hurt to pick up a cheap multimeter to test it. like i said earlier. Also based on my experience, it may be both the mobo and the psu. i have had a bad psu blow a laptop mobo once. it wasn't hard to figure out when i checked the multimeter and it was showing between 400v and 600v. all the lights would turn on and it would try to start for a second, but then poof.. dead. did it for a while too. from what i heard from the owner, it did it for a couple days before finally not starting at all.

    It needs to have the same connectors yours does now. If that Gigabyte has a 24-pin main then the test unit needs a 24-pin main. If the processor requires a 6-pin then, well, you get it!
