  IRQL_not_less_or_equal error and stride 6 error

Please help, I am pretty much computer illiterate and I have been reading through the posts here trying to figure out what I need to do, and I am completely lost. I installed new RAM in my mom's computer for her. I've done this before with my computer and never had an issue. However I had a really hard time getting the RAM into her computer. Soon after I installed it the computer began crashing when Internet Explorer is running and it gives a blue screen with the error IRQL_not_less_or_equal. I googled this and learned that I should do a memory test. I downloaded the program and burned the ISO to a disk. I then ran this program when booting up and it found all these stride 6 errors. I ran the test that did six passes, and then the more in depth test that did 11 passes. The stride 6 didn't fail every time. It failed on the 2nd and 3rd pass with the regular test and then it failed several times with the 11 passes.

I am running an:
AMD athlon 64 processor 3200+
Clock Speed 2.0 GHZ
Bus Speed 1000 MHZ
L2 Cache 512 kb

The memory channel mode is dual
the memory speed is 667 MHZ (however when I googled what type of RAM to put in the computer I thought it showed 533 MHZ. The RAM I purchased is compatible with 533 MHZ but it is running at 667 MHZ.)
Installed memory is 2.0 GB. I increased it from one stick at 512MB to two sticks with 1GB each) I read that the dual channel is better than single channel.
It is running DDR2 SDRAM
The RAM is running on DIMM 1 and DIMM 2. The ECC says NO. The Rank is 2. It is unbuffered and the organization is x8.
My BIOS settings say all this information is unchangeable. I was reading something about overclocking (which I don't really understand, however I think it is the clock speed.) I am unable to change mine from the BIOS settings, which is what I was reading I might need to do.
I am completely lost here, and the only thing I know to do is to remove the RAM and put back in the old RAM. My mom doesn't want me to do this. She really likes how she can actually use the internet now. Please Help!!!! Could the RAM I purchased be defective or is it something else. The computer is a Dell Dimension DimC521, and it is two years old.
