Q:

1 out of 2 sticks of RAM stops computer from booting

my computer stopped booting one day for some reason, so I bought a new motherboard, same thing happened, then I bought a new CPU and still happening!
Then when I decided to test the RAM sticks, I found out that 1 of the 2 was the problem. So when I have the problematic RAM taken out, my PC runs fine on its lone 2GB RAM. Both together there's no boot, and the problem RAM on its own still no boot.
I think this was the RAM that I tried to make a partition out of a year ago and is why I have problems.
Is there a way to reformat a RAM? I can't even get to BIOS with the RAM in the PC anyways... so how would that be possible? I checked the RAM stick, there's no burnt pins, everything's perfect...
My RAM is:
PATRIOT DDR2 2GB - 6400 (5-5-5)

A:

You don't partition RAM, you partition hard drives.  There is no formatting of RAM.  You must be confused.
Anyway the bad RAM is bad, there is no fixing it.  It may be under warranty,most RAM has a lifetime warranty.  Try contacting Patriot and see if they will replace it.
