After my first 6 months of mining, I have come up with a few pearls of wisdom for beginners:

90% of all mining program errors are due to too much overclock/undervolt
The other 10% are caused by errors in configuration
If youre sure the problem is not the riser, the problem is the riser
Never keep any wallets on a machine you use for mining
Its hard to mine the most profitable coin because its always changing
If you have to sell your mined coins immediately to pay the electric bill, you probably dont need to be mining (have some working capital)
The pool with the highest hash rate doesnt make you the most coins over time
Always keep older versions of mining programs, you might need them one day
When a new GPU driver comes out, let somebody else be the guinea pig
Time is money in mining. If your machine is down, youre not making money
Fine tuning a rig can be time consuming; dont let it consume all your time
If it aint broke, dont fix it.

Please feel free to add your own...

Power supply testers are $10-$15. I highly recommend getting one and use it for troubleshooting. It's a lot easier than shuffling cards and cables around and it will save you time if you ever have to troubleshoot power problems.
