Check out Step 10 of the "Step-by-Step Guide to Building a PC" sticky at the top of the Homebuilt section. It has a bunch of benchmarking and troubleshooting programs that would be good to run. Some of them you'll only need if you have problems, like MemTest86+.
OK thanks. I do read stickies... but I guess I should have read it a little better rather than just glance at it to see if it solves my problem
