Won't boot with both sticks of ram

[Nortrix0]

I got this pc for free and at first it worked, then after updating everything I restarted it and it wouldn't POST, after removing the 4gb ram stick it worked.  I've replaced the ram and tried it in another pc, it's fine am I missing something?

Hi,

have you checked  how acts Bios with one memory module in a PC and with two memory modules in a PC ?

With only the 2gb stick the computer works fine, if I plug in only the 4gb stick then it doesn't post

Your PC have two memory slots on motherboard  ,doesn't ?

Rule to use it eliminating a problem:

1. 4 GB RAM module could be bad or not matching motherboard spec.

Spec. are there- http://h10032.www1.hp.com/ctg/Manual/c03317456

page 13.

2. If you sure module is god . Test each slot om motherboard with that RAM module in it.

Test- put RAM module in one of the RAM modules. Restart Pc-enter -BIOS. If doesnt work -repeate procure with other RAM slot.

I have swapped the 4gb stick with another and switched the slots each stick was in, it's still only the 2gb stick that posts

Is motherboard BIOS  up to date ?

Have tray other  4 GB memory block being sure as that is in working order ?

I don't know if the BIOS is up to date, just took out the RAM to check and now for some reason its beeping 6 times which apparently means it's now also a graphics issue, I've just given up hope for it and am getting a cheap tower off of ebay.  At this point it'll probably be a motherboard swap that would fix it, but that'd be more expensive than the tower I bought and may not even fix it, it's just the motherboard and CPU are the only things that haven't been changed.
