I just got my ThinkCentre800z. All is fine except the fan noise! It almost drives me crazy!In BIOS, I already already put to "acoustic", but the noise is still there! Anyone could help me solve this problem?Thanks!

Thanks for trying. You could install a temperature monitoring program, like HWMonitor (free version), to see if temp is abnormal and causing the fan to run hard, but I suspect there's a hardware problem, and you should call tech support for service.

Thanks for your help. But now a new problem comes out. When I restart my computer, it says bios error, machine type or serial number is invalid. I think it is due to my bios update. Could you please help me solve this problem? Thank you.

OK. At the very bottom of the BIOS download page are downloads for the prior release, the one you were running previously.
I suggest you download that (version 42) CD ISO image, burn a CD, and flash back to the original version. Thx.
