From: tjacobs@bvsd.Co.EDU (S. Tyler Jacobs) Subject: Centris610 problem. Nntp-Posting-Host: bvsd.co.edu Organization: Boulder Valley School District Lines: 10 The problem is this: After starting up my machine it gives a high pitched sound once at the desktop also it only does it when the mouse is up or a menu is not showing. as if I click the mouse the noise goes away for the amount of time the mouse is down. also this problem only happens for about 5-10 minutes. please let me know if you know what this is, it sounds like it is coming form the power supply. Please Post here and Email me: tjacobs@bvsd.co.edu Thanks!
