Baffling PC problem.

Anyone ever heard of a Processor which fails only on the IDE channel? (Not even sure, I;m stating it correctly.)

I've been struggling to help a friend who's trying to build a low to mid PC. There is a 4800+ AM2, ASUS M2N68-AM PLUS, Corsar 4 gig 8500 and GeForce 8800GTX. We have tried to install WinXP Sp 2 & 3, Vista (don't tell anyone, please it's extremely embarrassing things got that desperate :p ) and Win 7.

I'll mention XP since it's a bit easier to describe, the system boots from the DvD, installs the initial files and on the first Reboot, it crashes at the first WinXP screen, with a Page Fault in a Non Page Area. That screams RAM issues, so on the phone with Corsar running down possibilities, settings and after about a week, they decide to send new replacement RAM. New RAM arrives SAME DAMN Error same place.

We tried installing from a IDE DvD (slaved on the channel) and a SATA DvD same error. Also tried removing the 8800 to try the onboard graphic chipset, same. We are using the brand new IDE cable from the Asus mboard and the hard drive isn't too old at all a WD 200 gig 8 or 16 meg buffer (can't recall atm). Tried an older spare motherboard, same. Then we tried a single stick of RAM 6400 512 meg, same error. The only thing we haven't tried is replacing the processor.

The weirdest thing (at least to me) early in the testing before getting the new memory from Corsar, we were able to get to XP desktop with a Thumb drive. So the processor seems to work on the USB, but we haven't tried a SATA drive (he doesn't have one, nor I a spare).

It's the processor, right? Is it possible for a processor to function but not communicate with the IDE channel in a Windows environment? It seems to function in DOS as it initially copies files from the install Dvd.

Btw on the Vista and Win 7 installs it crashes at the same point the first time it tries to start the Win environment after installing the initial files from the first boot.


Thanks for any help.

I would try running Memtest.

Have you tried booting from a 'live' CD? Ubuntu or Mint kinda stuff?

That's kind of wierd, but no, a CPU won't just fail only on the IDE ports. Something else is going on in your system.

It does sound like perhaps the problem is with the CPU though, if that's the only thing that you haven't changed. The memory controller is on the CPU die, so if you are getting "page fault in non-page area" (generally a RAM error, I think), and you've tried different RAM (make sure that the proper timings and voltage are set in the BIOS), then the problem is possibly likely to be the CPU.

The USB and IDE are both through the southbridge chip, so if it does one, it probably does the other.
