All downloaded files are corrupted. When I execute the file it will says "the file is corrupted", "XXX file is missing, redownload setup file". This is the case for a variety of different installers for different applications. Note, I get this error 9 out of 10 times. This is not just limited to installers, seems that all types of file are being corrupted. It doesn't matter if I download the file using Firefox or IE.

Also, if I try to use Bittorrent, I can see numerous hash fails reported in the console. Emule also reports corrupted data.

I have run CHKDSK /f and it reported no errors and no bad sectors were reported.

I tried using the Maxtor PowerMax diagnostic utility and it said the drive is fine.

When I tried using Azureus, I seemed to get BAD_POOL_CALL and BAD_POOL_HEADER BSOD errors, this doesn't happen with the utorrent bittorrent client.

I'm trying the 5 stage CHKDSK right now.

Strange thing is that Windows loads fine, loads in about 5 secs after POST.

Are there any other diagnostic tools I can use? Do you need any more information to be able to help me?

If they're large files and you're using dial-up, then the long d/l time may be causing the sorruption.
See if the d/l is more successful during off peak hours between 12 mid-6 am.

Files of any size are being corrupted, I have ADSL 1mb.

Did you check for viruses and spyware?

Did a scan. Found nothing.

Make sure the browser's cache is emptied before d/l'ing.

If that has already been done, then see if this helps:

Problem solved, my onboard Nvidia LAN was corrupting incoming packets, I'm using the other Marvell onboard LAN now and everything's fine.

Glad to hear that you solved the problem.
