Corrupted Files

[Guest]

Hi, I have been using Vista ultimate for some time and it seems all files i
download that are of the type .exe have a big chance to get corrupted, At
first i was told my HDD was faling me so I got a new one but the problem stil
remains.
It feels like that vista got some security that makes them corrupted when
they really are not, this in not just only in the download section, it
happens sometimes if i burn some files to a cd/dvd some get corrupted, if i
move some files over the network i some times get them back corrupted.

please help me.

No, you've got something else going on. I don't have any problems doing
anything like that on Vista Ultimate. The issue could be hardware or
software; we just don't have enough information from you to know. You'll
need to let us know your machine specs, network setup, and whether you
clean-installed or upgraded. Include what antivirus/security products
you are using.

I dont know how much to write but i will put down all I can find

OS: Windows Vista Ultimate (6.0 build 6000)
BIOS: Phoenix - Award BIOS v6.00PG
Processor: AMD Althon 64 Processor 3200+, ~2,0GHz
Memory: 1022MB RAM

I just got a new HDD so its a clean install only a few days old.
I'm using NOD32 antivirus system (with latest signature).
All microsoft security are set on default.
My network is thru a D-Link DI-604 Router.

I know it not much but if there is anything more you need to know name it
and i'll try to find it.
Here is an example of what just happend:
right before i got my new HDD i burned some data dvds to save some files, i
was on my way to install a program so I copy the exe to my documet folder and
executed, i get the message it is corrupted, i run it from my dvd and it's
not corrupted, I don't know but... if i move a file from a dvd to my computer
it's not suposed to get corrupted.

That's great information, thank you. Since you know the hard drive is
good (it's new) and since you aren't using McAfee or Norton (McAfee in
particular is known to destroy stuff), I would do two things:

1. Since the problem occurs when copying anything from the optical
drive, swap out that drive for a known-working one. I'm not sure what
you meant by "it only happens in the download section". If you mean that
files you are downloading - without the optical drive being installed -
then the optical drive can't be at fault. I wasn't sure exactly what you
meant so...

2. Do a RAM test. I like Memtest86+ from www.memtest.org. To be sure
that there is no problem with the download, get it from a different
machine and create the bootable cd from a different machine. You need
third-party burning software to burn the .iso. After you've created your
bootable cd, boot the sick machine with it. Allow Memtest to run for at
least several hours unless you get errors immediately. If you get errors
immediately, replace the RAM.

Is this a clean install of Vista that you did yourself or did it come
preinstalled on an OEM computer? If the former, is this a retail copy of
Vista or a burned copy? Notice that I'm not questioning the legality of
your Vista; I'm just trying various avenues of troubleshooting because I
can't see your computer and observe things first-hand. Also, did things
ever work correctly? If they did, what changed?

I Should add that its not only from my optical drive the files are being
corrupted, its like if i copy/download a file from optical drive, network or
internet it has around 25% chance of becomeing corrupted, and it happends to
most big files who take long time to transfer.
My copy of vista is a burned copy.

I have done some testing my self and tried dual booting with XP and the
corrupt problem follows even there so I know its not vistas fault at least,
I'm starting to suspect NOD32, I dont know why but it feels like its the only
program that goes thru all files at transfer and has the ability to do
something bad to them.

I will do the RAM test and get back.

This is really useful information. I suspect the issue is hardware, not
either operating system and not NOD32 (software). See if your drives are
in PIO Mode. MVP Hans-Georg Michna has a great page on that:

http://www.michna.com/kb/WxDMA.htm

If the drives (hard and/or optical) are in PIO Mode in both operating
systems, then I would suspect a bad motherboard (not RAM). Since the
problems with file corruption are not limited to the optical drive,
downloading (network adapter and networking hardware), I would look at
the RAM (because testing it is easiest) and then the motherboard.

I had one machine that had strange errors, corrupted files, occasional
BSODs, etc.
I reinstalled & reinstalled, swapped hardware (HDD, RAM, Video card, NIC,
Sound, eventually the MB) I did everything that I (and several other IT
guys) could think of.
Eventually I figured out that the cache memory on the CPU was bad.
I had never run into that before.
Replacing the CPU solved it.

Interesting. Thanks for sharing that. It usually isn't the processor,
but you're right to point out that we shouldn't forget it.

sound interesting. anyway I did the RAM test and fell asleep during it so i
had it running for 12 hours and the results were "30 pass" "0 error", is
there any way to test the cpu to see if it is the bad guy?

There are software tests for processors on various Ultimate CD's and
Hiren's. Sometimes these are useful and sometimes they aren't. Sometimes
just sticking in a known-working processor will show the answer. Of
course, you need to have extra processors on-hand and most end users
don't. At this point you may want to have a local professional take a
look. This will not be someone at a BigStoreUSA type of place. Subtle
hardware problems can be quite difficult to diagnose, and doing so from
the venue of a newsgroup as opposed to hands-on inspection is impossible.

I'm sorry that I was unable to help you.

It's ok, you were the most helpful person i meet in this problem so far
I will seek out an old friend and see if i can get some help there, stil i

That sounds like a good plan. Yes, if you do find out the cause please
post it. I'd like to know how the story ends.

Good luck,
