I have am M57 tower that has been running great for many years but now all of a sudden after changing a few settings in BIOS (I did not upgrade the bios) all I can get the machine to do is power cycle over and over again with fans at full speed. I attempted the steps here http://forums.lenovo.com/t5/A-M-and-Edge-Series-ThinkCentre/M57-BIOS-Update-Failure/td-p/55840 but no luck. I did not change any hardware recently. I have also removed the descrete video card in it but there is no difference. When I attempt to recover the BIOS via a usb desette drive it beeps once then reads the disk for about 5 to 10 seconds with the fans at full speed. Any help would be appreshiated. I never knew you could brick a system by changing settings.

Thank you for the reply. The cmos battery is just fine. Is there a chance I am using the wrong BIOS update floppy disk software? I got teh latest one off the the M57 drivers website.
