Hi,

I'm new to this place (Computer Cops), and I'm not sure if I'm posting at the right place...
So if I've missed something or if I'm posting in the wrong plaze, plz tell me how to do it the way you want.
If I've done wrong, slap me if you want...

Problem-Computer:
*AMD Athlon XP 1600+ 1.4GHz
*ASUS A7M266
*2 x 256Mb DDR PC2100 (AMD Ok)

Well, anyway.
Lately I've been having the following problem:

When using FTP to transfer files between two computers, the network doesn't use 100Fdx as it should do.
(Both computers have 100Fdx-cards and a nice 100Fdx-switch in the middle. (HP-Procurve 408), and the switch reports 100Fdx all the time)
But suddenly when it does try use 100Fdx, CPU goes off to 100%.

The transfer starts slowly with about 1000 kb/s...(a bit slow for 100Fdx?!)
The CPU usage is then about 50% on the problem-comp, and abouth 10 on the working comp.
Then suddenly it boost to 4000-6000 kb/s...but the CPU usage goes up to 100% on the problem-comp.

"system" = 50%
"ftp-client" (LeechFTP or FlashFXP) = 50%

HDD isn't really doing alot either...

This is only happening on one computer, the other one only get up to 20%CPU max during "full speed".
I've installed them both, so they are quite similar to each other.
And I've never had this problem on this hardware before...
It occurs mostly during upload from the problem-comp.

I've tried to change NIC to new ones, still problem.
I've tried to reinstall another OS (forst XP-Pro, then W2K), still problem.
I've tried other FTP-clients, still problem.
All SP's and WU-fixes is installed.
I've tried to install new drivers for PCI and other MB-chipset-parts..

I'm beginning to suspect the MB is faulty...
My antivirus (Panda Platinum) likes to shew up all my memory to...and Panda software cant find the problem...so it might be MB-hardware there to...
And I'm now getting this in the event Viewer:
* "The driver detected a controller error on \Device\Harddisk1\DR1. "
* "A parity error was detected on \Device\Ide\IdePort0. "

Any ideas about the "FTP 100Fdx & 100% CPU"-problem?

Thx for your time!

Edit: One FTP-Server used is BulletProof FTP v2.21.
One client used alot is LeechFTP 1.3
