I have an NEC XV17+ monitor. About a year ago it started making noises ( a high pitch whine ) when running at
1024 X 768. I think I fixed it by selecting my specific monitor in system settings ( the previous setting was generic monitor ). I recently upgraded to Win 98 and reformatted my hard drive. Now my monitor is making that noise again. It only does it at 1024 x 768. I can switch to a higher or lower resolution with no problems. My video card is an ATI Mach 64 Video Expressions.
