CRC errors with core 2 duo?

I've had this problem for quite a while now. Almost every time I try to uncompress a file (particularly one with multiple split archives) or install a game, I run into a crc error. The keyword is "almost every time" because there seems to be no rhyme or reason to the error. It will occur at 58% once. Then, after I've replaced the archive files from the SAME SOURCE (e.g. a USB hard disk), it will give an error at, say, 65%. The odd thing is that if I copy those "faulty" archive files to another computer and uncompress, the thing installs flawlessly. Which means the problem is not in the data but occurs during the "decompression phase".

I've replaced my hard disk thinking that since it was getting old, bad sectors might have been the reason but no luck even after installing a fresh copy of windows on the new hard disk. I've replaced my ram with another to see if that would solve anything but the error persists. The only thing culprits remaining are the CPU or the motherboard and I would appreciate it if someone could help me out.

Is there any software out there that will let me pinpoint the cause of this error?
