High pitched squeal

[daphatgrant]

Hello, I have a secondary rig that is causing me some serious irritation.

Specs:
K7N2 DELTA2-LSR
XP 3000+ Barton
1gb Corsair XMS PC3200
BFG 6800GTOC
SB Audigy
Maxtor 120gb hdd

Problem: There is a ultra high pitched whine or squeal emanating from the case. Here's the weird part, the noise will disappear if I have a webpage open and use the scroll wheel on the mouse to scroll up and down. As soon as I stop scrolling the noise starts again. I have tried different video cards, different mice, different monitors, but have not come to make since of this weird problem. If there are any thoughts out there please let me know. I am thankful that this is not my main rig or I might have thrown it out the window by now .

This sounds like motherboard coil whine to me. Try replacing the motherboard and see if that solves the problem. If it doesn't, it could also be problem with the PSU.

Yah, I agree with backslash. I've seen that problem before. I replaced the PSU and that solved the problem.
