A very weird PC ?performance? problem

[nimo]

A friend of my decided to upgrade his MB to GA-7N400-L

The spec oh his PC:
GA-7N400-L MB
1000 T-bird (C)
256mb pc2100
Maxtor 60gb
Matrox g400
Generic CD

Windows 2k and 98 installed with out a hitch (clean install)

Now the problems began

If you tried to copy a large file say 150+MB
The CPU would go 100% use
And it will take forever and a day to finish the copy

Playing any *.avi ? *.mpg ? files the same thing
And they ?jumped?

This was not the case with the old MB

Basically any even minor load on the system causes a continues 100% CPU load

After hours of tweaking and several clean reinstalls
Both on board IDE controllers were disabled
And PCI ata133 was installed

Now every thing works perfectly
The same IDE cables are in use and the same order master/slave is maintained
The same windows are installed
Same drivers and everything


Other then to assume that both on board IDEs are busted
What could cause this problem?


Tnx

One possibility: If Windows is trying to generate thumbnail preview things of a media file, and the media file is *AHEM* 'very large' for some reason *COUGH*, then it has to chew through oh, 2-3GB of data to generate a preview.

Example picture

Beyond that, ensure that the drives are running at DMA mode and not PIO mode, that you don't have any viruses or Trojans, and don't forget to get your latest Windows service packs and patches followed by a reinstallation of the nVidia unified driver pack from nVidia's site. Good luck

hehe that 3.04 Mb movie file is sure large! :Q


Back to the topic: Did you use NTFS as the file format?

Another thing might be the indexing service on the NTFS drives, you might want to turn it off. I remember installing NTFS on my first Win2k install and had to completely reformat back to Fat32 after experiencing the same things you described (took 6 hours to xfer 2 gigs, movie files were choppy, etc...). But then I read about the indexing which might've caused this disk problem.

Hey, I'm strictly an amateur at this You can watch teh m0vie here if you want to see what it is: quick & dirty I know at least some of the people around here will be scandalized... :evil:

 

[nimo]

Only FAT32 was used
This PC doesn?t have and never had access to the net
And it was a clean install so Trojans/viruses are out of the question

Ok, what are the 150MB+ files being copied from? From CD, DVD, another hard drive...? Not to get carried away on the virus tangent, but do remember that a virus can come in via a burned CD, not just from Internet/email.

Anyway, if there is a problem with the data transfer from optical devices or hard drives, confirm that the IDE controllers are running the drives in DMA mode and not PIO mode, and be aware of Windows' determination to generate thumbnail previews of media files unless you disable that capability in the folder view options.

Well with the PCI IDE every thing is running fine
So I think its safe no exclude any virus or such

As for the DMA/PIO modes I?ll check if we missed that one
tnx

I had a similar problem with my gigabyte board. It turns out my problem was, I had the primary harddrive in IDE1 when it should infact be on IDE2. I switched them, and the jumping, cpu usage, and forever to copy files vanished. Give it a try and tell me your results (unless of course you already had them on IDE2), and good luck!

It seems you have a hardware problem, but if this is happening when you are working in or with video files, then it could be a Windows problem: see here

This was what i did to resolve it.
