memory faulty?

[bullet]

Hi there, my computer has been playing up lately, running slow blue screens ect. So I ran memtest86 to check if my memory was the problem for a few minutes and I had a lot of errors. My memory is Kingston HyperX Genesis Grey 8GB. Here's a picture of the errors http://imageshack.us/photo/my-images/812/io8v.jpg/ So is the memory the fault of the problems.

Edit. I just done the test again for 1 hour and here are the results - http://imageshack.us/photo/my-images/600/rb8s.jpg/

Thanks
