I have an A1200 Power Tower.
I had the same problem as you.
I will now tell you the top-secret trick to fix the problem.
Keep in mind that many brave knights died in battle to acquire this information and only the oldest, wisest and most powerful wizards know of the existence of this darque majix.
Ok
The secret is
...
Duct Tape. I will wait here while you finish laughing.

The problem is that your 060 card is a teensy bit loose and it is not standing perfectly vertical. It is leaning a bit to one side. Open your A1200 PowerTower up and verify this.
When you see that it is a bit off, you can then point it straight up and down and tape it in place with duct tape. If you are a very high level wizard with a high intelligence stat you may choose electrical tape instead.
If you think back carefully you will remember that somebody bumped your computer the day that this problem first started. Perhaps they were reaching for something. The bump knocked it off whack a bit.
