Sound skips when CPU is "working"

Hey there, I'm having a similar problem. I just rebuilt this system for my mom, So these are all new parts.

Specs:

MSI 945GM3-F Mainboard
Intel E2200 2.2GHz Pentium Dual Core Running at default speed.
2GB (2048MB) DDR2 667 Dual Channel
Diamond Extreme Audio 7.1 32bit
Samsung SP0802N 80GB 7200RPM IDE/ATA100 (a spare HDD I had)
nVidia 8600GT 256 DDR3 PCI-E

Comment: The Audio and Video card I just put in today. In an attempt to remedy the problem. Not successful.

Problem: When the CPU starts working the sound will crackle and pop. Thats why I put in the new sound card. There is no way there could be spyware/adware/viruses because everything was just installed.

Examples:

While watching a video on youtube, the processor works to temporarily save the information, thus the sound skips. When the video has finished loading the sound smooths out and runs perfect unless I run something in the background.

Window Media player will run ok untill I turn on a visualization, it will skip a little. Then I minimize windows media player, and it skips so much that you can't even tell whats playing.

While watching a video on VLC Media Player, the sound skips every second or so. The video stays smooth.

It seems to run games fine except when loading. It will skip sound until the processor finishes "working"

Conclusion:

It has to be something to do with the CPU, I'm not sure what though. I've tried en/disabling "SpeedStep" But that has no effect. I have not overclocked anything because it isn't my system.

Any help will be MUCH appreciated.
Thanks in advance.

 

First thing I would say is the sound card but sound like you did that so next check any and all drivers and update as needed then the cpu just any cpu that fits and is if it stops or put that cpu in a different systemand see if the sound is crazy there too and finely the mobo maybe bad/going bad

 

The mobo is new as well. I don't have another Intel system, and the old processor is an older pin-in-hole design. (celeron D) I'm thinking it could be the HDD, it's the only not new part in the system. Was just one I had laying around. I think I'll try running some sound/video off of another HDD and see what happens. Wish me luck.

Tried a different HDD but it still does it. Changing the processor affinity to a single core seems to help a little but not much.
Anyone have any ideas of what could be going on?

 

I'd say the motherbaord is bad. Yes, I know you said it's new, but even new boards can be lemons from time to time. One positive note: if it's new, then it's covered by a warranty and you should be able to get a replacement at no charge other than shipping.

 

Dude Medicinal! My dad just found the problem with mine. It sounds exactly like what you're having a problem with. I did it, and it my computer is all better! This problem only happens when you're having disk errors/problems though. So, you'd better backup your disks, cause it/they might crash at some point... Hope this helps and good luck!
