Wierd Data Corruption issues...

[alphakry]

I can't seem to trace this problem back to a specific piece of hardware, so I was wondering if any of you have experienced a similar problem before.

I seem to be having a problem with corrupt data, namely downloads. A few other odd problems are occurring that I think relate to this problem:

1) If I download a file that takes more then a few seconds to download - for example, a 20-30mb driver installation file from nVidia.com. The file will download completely, with no indication of any problem - but when I attempt to run it, it will indicate that files it is attempting to extract are corrupt. This happens say 60% of the time I download a file.

2) BF2 will kick me out of servers, quoting "modified data" as the source. So I uninstalled the game - cleared out any trace of it - then reinstalled and repatched... the problem still happens. It's not consistent, as I can get on servers about 70% of the time - but now and then, whatever punkbuster reads on the hdd to monitor file modifications is having a problem with some of the files...

3) Need a bit more proof, but the drive seems to need defragging more frequently then I’ve ever noticed. I've been running almost nothing but BF2 for about a month, and have had very "red" defrag graphs at least twice.

Now you’d think it'd be a HDD problem... but it's only these situations that it occurs. Windows doesn't crash; things run smooth otherwise... so I’m not sure if it's the HDD. I've read somewhere before that these kind of issues could be traced back to as far as the PSU. So I’m not quite sure what could be causing this...

I ran oczmemtest for 19hrs - no problems.
Prime95 for 9 hours, no errors.

Any input as to what may be the cause?


Hardware:
Western Digital 160GB SATA2 WD1600JS
Asus A8n-SLI Premium - 1011 Bios, 6.66AMD drivers
eVGA 6800GT - 77.77 Forceware
Ultra X-Connect 500W PSU
OCZ 2gb Platinum 3200 Dual-Channel
AMD 3700+ SD


Cliff notes:
a. downloads complete 100% but are often corrupt
b. BF2 will display modified data errors and kick from server.
c. no indication it is just a HDD error.

here are two of the odd errors from BF2 which initially had me thinking it was a RAM problem:

this happened directly after killing someone... doubt it matters, but i noted this.

this happened at about 62% loading a new server map.

The latest ASUS A8N-SLI Premium BIOS is 1007.002 I'm pretty sure, and that's beta. I'm thinking this could be being caused by an improper BIOS flash.

i saw this... i think they may of took down their other beta version of the bios, because i'm fairly sure they were up to 1011 before... i will be reflashing the bios tonight to the most recent official release, just to be certain... thank you for pointing this out.

One tip, when heading to ASUS site for BIOSes, don't ever click the North America page. Go to the global page, it's in English, but actually is updated more than once a quarter.
