The IRQ's are auto assigned in 7 - you can try to make 7 switch by disabling the serial and com ports to free up resources. IRQ's are assigned by ACPI and the OS, if I remember correctly.
@AaronDude - you can virtualise Ubuntu. Boot into 7 and set up VirtualBox. The only caveat is hardware resources. You need at least 1GB for Ubuntu in a VM, and a solid CPU - what are your CPU and RAM details?
I have been experiencing this problem for a few months now, and I just resolved this issue. I saw that one use had updated their BIOS and it solved their issue, so I did the same and it worked.
For others with the same problem I am on 64 bit Windows 7 (issue occured in 32 bit as well) and I am using an Asus F50SV. I was on the 203 BIOS and upgraded to the 205. If you are using a F50SL you are in luck, actually, as the latest BIOS is listed as the BIOS for fixing this issue.
Hope this helps someone.

I have 8 gigs of ddr2 ram and a core quad 2.5 ghz.
I don't understand though, wouldn't I have to be running ubuntu separate if I want it to run properly? See, the reason I want to run it is just so I can avoid those nasty DPC latency spikes that obviously seem to be W7 problem. Otherwise I'd be doing it for nothing. That's the reason why and really the only reason why I want to run it. I decided I'm not going to use this computer to play home made RPGs as I originally intended and just use it for lite normal use such as web surfing and listening to music. That's why I want linux, I just want a computer that works even if that means sacrificing all the good windows software.
Now, I don't know how to install it really but I'm asking that on another board and browsing tutorials.
it's not a driver problem. have a look at this thread. Music flickers/crackles in Windows Media Player when browsing the Internet
Here is how it somehow worked for me
I replaced MB's battery to try to solve another issue and i after this the popping and crackling was gone.
Well I've been doing a lot of stuff trying to figure this out and have decided that Acer isn't worth a darn when it comes to troubleshooting. Anyway, what I did was disable the Firewall and Defender services as one member suggested. That helped a little bit but the problem seems to be the acer installed Artheros wireless adapter. If I disable that and reboot it is fine. It stays generally in the green but will go in the yellow and short reds for a while if I launch a program or close one and rarely in the high red. The spikes seem to go down if I launch winamp as well. Using the DPC latency checker on my laptop it stays consitant at about 1000. On my windows 7 desktop with the problem it fluctuates. Should it be staying consistant or is some fluctuation ok? The problem is I have to disable and reboot if I want to do anything besides go on the internet.
nevermind, It's back to doing it again even with the adapter disabled and multiple restarts. Windows 7 just sucks.
I've been having this problem for some time now (since vista). I've used the same computer the whole time (Realtek on-board audio). I didn't have crackling problems with XP at all. Period.
When I have Aero enabled Stuttering goes away only if I have music or something playing while scrolling down/up a web page on the internet.
When I have Aero off, it does it everywhere for no apparent reason. Movies, iTunes, Web-pages. Constantly.

I am experiencing this problem also. My variation is that it works fine most of the time and occasionally appears to just freeze for a split second. I am running Windows Server 2003 R2 x64, so the problem isn't limited to Windows 7.
I ran the DPC Latency checker tool suggested in this thread. With Easy Tune 6 running, I saw a distinct spiking pattern of red-green-red-green. The greens were around 35-40us and the reds were up just over 4000us. With Easy Tune 6 stopped, all of the bars were in the green. I think that ET6 makes the problem worse, but isn't the cause of the problem. I do get the occasional pop with ET6 stopped.
Running World of Warcraft helps to induce pops. Any time I have WoW open in a heavy area like Dalaran, DPC latency will randomly spike up into the yellow around 800-900us. Those spikes can be made more lengthy by moving around and rotating the camera although they generally don't go into the red. I have also noticed that when the audio pops, Direct 3D rendering seems to jitter a bit also.
I have Ubuntu 9.10 installed also, although I don't use it very much. I rebooted to Ubuntu last night and didn't notice any pops over about 20 minutes of playing music while running WoW (via wine).
