Hello,
after 10 days of troubleshooting I finally am frustrated with my new Shuttle XPC SN25P - I have no idea what to do now so I hope for your help.
Two weeks ago I bought a new SN25P with Athlon 64 3500+ (Venice, E6 Stepping), 2x 512MB MDT Ram, Samsung Spinpoint 200 SATA2 HD and a WesternDigital 320GB HD).
After putting all parts together everything worked fine the first day - the SN25P was silent running.
But since the second day the CPU Fan is running at full power and I am sitting here in front of my PC with an Ear-Protection ( no joke ).
Since then I did many searchings in several forums and supportlists and tried out any hints and infos I found all over there:
I flashed the Bios to Version Y, installed the newest NForce Drivers (6.66, but without IDE-Driver), the latest Athlon 64 Drivers from AMD and so furth and so on...
Nothing helped: If the SN25P is turned on, the Rear Fans (on the backside) run at Full Speed for one second and then go down immediately (so these fans work as they have to). But the CPU Fan stays at full speed. So I think that the problem is about the temp-recognition inside the Athlon 3500+.
I then took the complete PC into its parts again and even took out the 3500+, cleaned it from the thermal compound and spread a new layer (extra thin) of the thermal compound on the CPU. I pulled the ICE-Heatpipe-Screws as firm as possible. But nothing helped to solve the problem that the CPU Fan makes a hurricane so that papers are flying over my desktop .
I use the program "Speedfan"(Version 4.26) and it is showing me the following: Fan1: 3444 RPM (thats the CPU Fan running at full speed - sounds like a starting jet), Fan2: 1671 (thats Ok). Temp1: 36C, Temp2: -55C, Temp3: -55C, HD1: 36C, HD0: 29C. I am able to control the Rear Fans on the backside of the SN25P (Fan2) with speedfan, but the CPU Fan does not react to whatever I try with speedfan.
Nvidia Ntune is showing absolutely no temperatures (although every options concerning this are checked) and the Software "Everest home edition" does not show any CPU-temperatures but only the harddisc-temperatures.
So I think that it is indeed a problem with the CPU-Temp-Recognition.
But now to the main-problem that sticks together with the whole issue: The SN25P is running perfectly with Windows XP and boots up without problems, but since the second day it is impossible to get into CMOS Setup. Whenever I put the "Del"-Button only a blinking Cursor appears in the upper left corner of a black screen - the keyboard is dead - only a complete reset helps.
I then tried to repair the Bios: Cleared CMOS - with the Clear CMOS button on the back of the SN25P; with Jumper-setting to clear cmos and even with taking out the battery for over 15 hours. After rebooting it then says "CMOS checksum error" so the CMOS-Clearing seems to be successfull. But it helps nothing - can not get into CMOS-Setup.
So I flashed back older Bios-versions - version O, version K and others... nothing helped. I flashed with the program "Winflash" and later I made a bootable CD and flashed with the program AWDFLASH trying out all given options like "/py" "/sn" "/Wb" "/cd" "/cc" "/cp" "/LD" "/Qi" "/cks" in different variants, so that the bootblock has been deleted and rewritten, the DMI-Pool was built up again and and and. I think that I flashed the Bios over 10times until now (formidable that the Bios-Chip took part in this permanent load) - BUT NOTHING HELPED - I SIMPLY CAN NOT GET INTO CMOS SETUP and the CPU Fan is noisy as hell (a wonder that my neighbours havent yet called the police )...
And after all I can not understand that - because the PC is running with no proplems under Windows - so the Bios works perfectly! But as long as I can not get into the CMOS-Steup I am not able to change the SMART-FAN-Configuration or to verify whether the CPU-Temperature is detected right in the bios.
...*** PLEASE HELP ***...
