Computer crashes while downloading files from the internet

I am having a issue with my XP machine.

I am running XP professional
2gb Corsair pro ram
AMD X2 6000
Asus Crosshair AM2 motherboard
8600 Graphics Card
1 WD 320gb Main HD
1 WD 500gd Secondary
1 Maxtor 500gb Secondary

The problem is that when ever I try downloading large files from the web my computer goes Blue Screen on me and
has these messages


Kernal Stack Inpage error

0x0000007
0x00000f4
0x0000003
8978a748
8978a8bc
805d11f8

Also I get Process or thread crucial to system not functioning

And Windows System error unknown hard error

These are what I have seen so far, and it only happens when I download form the internet.
Not when transferring files or doing any other process.

Also it doesn't matter what HD I am downloading to or if I am using a download program or the standard IE download.

I can't seem to find any info related to my problem any where.

I have run diagnostic software form PC Doctor on my PC and Nothing comes back bad.

The Hard Drives have all checked out with the diagnostic program as well.

I am at a lost and have no idea how to go about fixing it.

I have a feeling it is either motherboard or software related.

If you have any suggestions please help.

Thanks in advance.

here is a couple of links that may be helpful.
One of them speaks of the event viewer. Do that. and see if it gives any additionial info.

I had the error today again and this was the error message.

Kernal Stack Inpage Error

0x0000077

Stop: 0xc0000185 0x00000000 0x0049c00

This is maybe the second time I have received this particular message.

If Any one knows how to decode this please help.

I have looked at the links above and there is a description of what the error messages are but I am not advanced enough to fix the problem.

Is it possiable to downloads too fast and overload the HD.

I get 780k average when downloading. Some times I have multiple files running 700k each.

Could this cause the problem.

Thanks for the help.

I decided to run a few more test today.

I transfered files roughly 80gb from my sata 500gb to my main sata 320gb and after about 25% transfered the computer crashed.

I repeated the process with the maxtor 500gb and the sata 320gb with nearly the same results.

I then transfered the same data from the maxtor 500gb to the sata 500gb and they completely finished.

This led me to the conclusion that there was an issue with my main HD the WD sata 320gb.

I ran the chkdsk.exe program and did'nt get any errors that I know of.

I have been wanting to upgrade the main HD to a WD Raptor 150gb 10,000rpm so I decided that now would be a good time.

I installed a fresh copy of XP Pro Sp2 on the raptor.

It has seemed to fix my problems that I have been having since day one of my computer build.

I have been able to transfer file from all HD with no problems and the download problem has not been an issue so far (fingers crossed).

So I believe the problem was caused from the WD 320gb and not the motherboard.

I however cannot rule out a software issue because of the fresh windows install but I have noticed much better performance all around that matches more in my mind to what the computer should be able to do, that it wasn't performing with the WD 320.

I will be giving newegg or WD a call soon for a replacement drive.

Thank you guys for all your help, I really appreciate it.

Glad to see that you got it sorted out. I read in a couple of the links I gave about the WD issue and hoped that wasnt the trouble but im glad to see that you saw it also and trouble shot until you knew for sure.

ps one thing to possibly try would be to see if a firmware update is available for the drive. I hate to see a working drive go to the crapper. I would think that WD has to be aware of the problem.
