Onboard sound(included it due to the sound issue)
I about a month or so, upgraded(clean install) myself from vista to Windows 7 x64 ultimate. It was very exciting to see the new features and the performance of the OS compared to vista as it boots,open programs faster and manages processor and memory much more nicely. Getting used to this new OS was very fun but after all that stuff, I had problems due to Intel because it didn't release all the new drivers needed for the OS(bloody hell!?).
So, I got very much disappointed but i thought it was no big deal as I'm missing only one driver: The "PCI simple communications controller" which I presumed to be the Intel ME interface and the sound driver is not a problem as it is given to me by windows 7 and it works good but not quite nice as there's no dolby support =(.
Now, on to the problem, Im having this weird sound issue which basically comes from both the CPU and my headphones that I constantly wear. It's sounds like a High frequency/pitch sound that is not quite loud but audiable and gets annoying after hearing it for a long time. To summarize it:
- It's not constant.
- It's not the fans. (I started the cpu with all fans off except the PSU and proceesor fan but I cleaned them and still have that issue)
- It's not a hardware fault.(I replaced the video card, PSU, etc and still have the issue)
- It only seems to play when i use Firefox(opening tabs, scrolling, webpage loading) and paint(scrolling) but no issue on IE or any other software.
- It does not come when I play games or any other CPU,GPU intensive program.
- It seems to be an issue after the upgrade to windows 7 x64 as with vista i had no problem like this.
- I ran many benchmarks and tests to make sure but didn't had that issue.
So, right now i have some suspects regarding this issue. It might be the drivers but I'll appreciate it if someone has the board like this with no issue on Windows 7 x64, also. This problem came only after the upgrade to Windows 7 because i used win vista with firefox and other software with no issue like this and I even reinstalled vista to make sure and i didn't had that problem there but upgraded again as vista felt slow and had loads of updates to complete. So now i have shrunk this issue to the drivers but im not so sure and I will really really appreciate it if someone helps me here because this problem is getting on my nerves and even after a month im unable to solve it.
EDIT: Found out the problem, It was caused from upgrading the bios to ver. 0572 and somehow it was bugged. How I found out was by changing the processor by borrowing my dad's e8400 processor and installing it into the board. Hoping not to have a same issue and seemed it worked, no noise,clean and stable running system. Then, putting on my own core2quad it came again. That made me wonder
, and I tried to mess up the bios settings, hoping to find the problem.
So, after much disabling/enabling testing, I came across this option dubbed "Enhanced Intel Speedstep Technology". Disabled it and rebooted, then what? No more noise! and the system ran smooth without any problems. Went to learn about this particular technology and found out that this option when enabled will automatically down-clock and up-clock the processor clock frequency in real-time due to the condition it's in, for example, it down-clocks the frequency when to 2ghz and when running on full speed to 2.33ghz on my processor. This makes efficient power consumption and reducing heat, that seemed a good technology but it caused considerable problems for me.
For a checking reason i installed cpuid pc-wizard and checked my processor and it showed 1999.31 Mhz current clock and by checking the technology tab on the details list it showed that speedstep is enabled but dynamic fsb is disabled. So, dynamic fsb caused problems on this processor
(huh!). But I happy that my problem is now long gone and i thank again the posters for their contribution.
As for the headphones problem, It was caused by a bad front-panel and it had a little short-circuit on the usb port and when plugging anything on it caused the noise.
