RAM causing BSOD

[Symbiode]

So I have an old pc form 2010 and I added a 2GB ddr2 (had a 1GB ddr2 ram pre-installed) ram to it. It's running fine until a couple days ago. For some reason I was getting some sort of display problem so I just took my gpu and the ram out one by one and checked it. The problem not being fixed I put all of them back in but my pc started showing Kernel Security Check Failure. I restarted a couple times but it didn't help. Then I took out my 2GB ram and it worked fine. But the problem is the other 1GB ram is just too slow to work with. I don't do any heavy work, just some light stuff like playing games, going on the browser but my pc would just keep on freezing even while just using chrome. I swapped the slots and everything. The 2GB ram just does not work. I'm thinking of replacing the ram in case it works.. even though I'm gonna buy a pc soon. But until then I gotta live with this old pc but I want it to work

If I read correctly you have 3GB of RAM ?  That is odd.  Try one at a time and see if your problem is fixed.  When you say the other RAM is too slow,  It has to be synced with your current RAM speed.  So what effective speed you running ?  Also fill in your signature we can help you better.

Yup 3GB of ddr2 ram. I have tried one at a time but only the 1GB ram works. If I try to use only the 2GB ram it still causes that BSoD and keeps restarting.

Seems as tho the motherboard could be botched.  As long as all sticks work when you put in 1GB that means its not the RAM and its a faulty mobo.

Oh no... the 2GB ram doesnt work no matter what. Even if I do put the 1GB ram in or not.
