Well, that's the problem, the TBGM01 mobo is proper to Gateway(Acer) and the P01-A0 BIOS is AMI structure but modified by Gateway(Acer) so AMI can't suport it. The updates available are the only ones. :S

I resolved the issue by disabling core parking in reg edit and also by installing some intel softwares such as; Intel Turbo Boost 2.0, Intel Processor ID utility, Intel Rapid Storage Technology. As for the BIOS, I'm skeptic over it. If you look carefully at my last post you'll know why. Thx a lot for your time and help.

My BIOS is ¨P01-A0 and the update is named R01-B1, does it matter....? I mean, my pc is 2 years old,I bought in 2010. They might have changed the BIOs since then...Can you please tell me the signification of these P01-A0 and etc ? EDIT: I believe my BIOS is not the same since their "updates" are older (they were last modified in 23/5/2009) than my BIOS's (dates from 08/08/2009). I also tried disabling my devices in device manager but with no success. By devices I mean; Realtek on-board soundcard, USB Razer DeadthAdder Mouse, USB HP Multimedia Keyboard, Nvidia GeForceGTX 260 (GPU), DVD read-writting hardware. I tried re-updating to the lastest drivers but changed nothing.

but will it SURELY resolve the ACPI.SYS problem ?

I am currently disscussing with gateway and Acer customer service about my BIOS. To be honest, I have no idea if I should flash my BIOS. I don't want to screw up my system because this BIOS update is not for the BIOS I use or something like that. My question to acer: I currently have a Gateway Fx6802-07c bought from Futurshop in january 2010. I would like to know if the current BIOS update available for the 6802 on the Gateway site (R01.B1, 06/29/2010) is valid for my system. Motherboard: TBGM01 / BIOS: P01-A0. I ask the question here since the Gateway support told me: Flashing the wrong BIOS can cause harm to the system. Acer recommends that you should only upgrade your firmware/drivers if you have been instructed to do so by an Acer Customer Care representative. By using these firmware/drivers you agree to accept the possibility of product failure. Acer's response: Response 02/14/2011 11:52 AM Dear Ric Ric, we does not recommend the BIOS update. If the system is working fine then there is no need for a BIOS update. If the system have any known issue and if the BIOS update is available to resolve that issue then you may do so. I sent a reply that says: Well that's the problem, ACPI.SYS hogs 2 of my cores under NT & Kernel by using a steady 15-30% of my CPU. I want to know If the BIOS Update is valid for my BIOS so I can update it just like all of my other drivers. I am currently trying to resolve this problem by elemination process simply by updating my drivers one by one. Reinstalling Windows 7 did not fix it. Acer answer: As per your mail we understand that you are experiencing an issue with CPU usage and you need to know about BIOS upgrade. I apologize for the inconvenience that you have experienced. You may please go through the following link to find the BIOS update available for your system. http://global-download.gateway.com/GDFiles/BIOS/BIOS/BIOS_Gateway_R01.B1_A_A.zip?acerid=634133888894332578&Step1=DESKTOP&Step2=FXSERIES&Step3=FX6802&OS=ALL&LC=en&BC=GATEWAY&SC=PA_6G Since it is a BIOS update for this model, it won't cause any harm to your system. We don't recommend flashing the wrong BIOS, since it cause harm to the system. By using these firmware/drivers you agree to accept the possibility of product failure. I stripped their posts of the un-usefull info for you and me lol. My question to people who read this post, would it be safe (please investigate) to update my BIOS and would it resolve the ACPI.SYS (DPC_INTERRUPT) issue which causes an average 15-30% CPU usage on my i7 920 ?

Hi there,I followed your guide and got a rar file for you. I know who are the culprits but I am wondering how to handle this and why are there so many with the value uSec over 250. I try to keep my hardwares up to date as much as possible. Only my BIOS has not been updated yet but there is a side story to this. Rar: http://www.megaupload.com/?d=7O7QN817
