Windows 7: CPU goes through the roof when syncing on iTunes

CPU goes through the roof when syncing on iTunes

First, my system info:

Acer Aspire x3200-U3600A, no modifications
AMD Phenom X3 8400 triple core processors
4 GB DDR2
320GB SATA hard disk (partitioned C: and D: drive, OS installed on C: )
Nvidia GeForce 9200 graphics card

My PC came with Vista Home 64-bit installed. My school offered a free upgrade to Windows 7 Professional x64 so I decided to give it a shot.

It's been a nightmare ever since.

When I tried to upgrade, there was a conflict between my old OS and the new old, so I had to do a full install. The install program warned me I'd lose all my files, so I backed them up onto an external drive, but they're still on C:, just with the .old extension added on.

When I try to do something major, like multitask or transfer many files or do a large sync on iTunes (yes, it's the 64 bit version), my CPU jumps from normal up to 90-100% and stays there even after I shut down all applications. It doesn't freeze up my system entirely (mouse/keyboard still work) but it makes everything lag and stutter terribly and effectively makes my PC useless until I restart.

I've been trying everything I could find on this and other forums and nothing has helped.... updated my BIOS, my audio drivers, my wireless USB driver, my graphics card driver, turned off indexing, uninstalled iTunes and AVG... nothing is working.

If anyone has any ideas, I'd be very, very grateful!!

I'm very computer literate but not highly skilled with background processes, so please list detailed instructions.

I have process explorer installed already if that's of any help.

Sounds very odd, before I read this I was going to say blame iTunes, well for obvious reason (Apple hates Microsoft).

Have you tried doing a clean install? Since you already have your stuff backed up, it shouldn't be too much trouble.

After the reinstall, try multitasking again and if it still is doing it, let us know.

Basically perform another full install.

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.

Not quite, even if you did, don't you have everything backed up already?

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.

Have you ever thought about alternatives to Itunes? Personally I've had a lot of problems with Itunes hogging up resources or locking up, I use winamp or gtkpod.
