CPU goes through the roof when syncing on iTunes

No, you won't need to reformat. But you will lose everything you have on the hard drive.
B4 U do that tho, have you performed any mods?
RU overclocking?
Itunes does use a lot of resources but you say cpu usage is intensive after you synch?
I suggest you go to computer management and see what services are running after you finish synch.

I'm not talented enough to mod. That's why my computer is stock

I can sync for a few minutes, typically, but after a while the cpu goes up to 90-100% and stays there until I restart. I can't finish syncing...it gets so slow that it times out on my iPhone and essentially freezes up iTunes. I just ran process explorer and it says that DPCs and Hardware Interrupts are taking up about 60% and 38% of the CPU usage, respectively.

Paradox, look at your device manager, I wonder if you have any IRQ conflicts, speculation there, as I was saying. Check your USB driver with your IPhone attached. It should show like the attached screen shot.

Looks good to me. (screen shot attached)

Hmmm... dunno, guess I'll check that out.

BTW, I've reinstalled Win7 and nothing's changed. And I haven't even reinstalled iTunes yet so that's definitely not the culprit.

Whoa, what are those to alerts in the middle of your USB drivers?

Well whatever it was, they're gone now.

Thats good news, re-install your itunes for windows 7 and let us know how it went.

Well, I've reinstalled Win7 and I'm still having the CPU problem... and I haven't even installed iTunes yet. So that's definitely not the problem. As I mentioned way back in my first post, any labor-intensive activities - file transfers, multitasking, syncing - do the trick. And I'd expect that... the problem is, once the CPU usage breaks 90%, it stays there, even at idle, until I restart.

Parodox, check your device manager for me, last time you had some drivers that did not install properly and then later you said they disapeared!

The USB drivers are all fine...the only thing coming up funky is "Other Devices -> Coprocessor". I tried automatically searching for a driver not nothing was found for it. The info on it says that there is no driver installed. I guess this could be the problem, huh? Although....it says it's not using any resources because it "has a problem", so would that even affect my CPU?
