I can install and play games from CD's and DVD's no problem. The problem I have is when downloading and installing patches or downloading (Legally - I buy them and get them with downloader programs) games from the internet. Frequently when doing this, I come across MD5 errors during the installation that cause the installation to fail. I've done a complete reformat of the computer and still come across the error.

Is this something that can frequently be attributed to hardware problems? The only times I encounter any unusual errors is during these installs, not during other times.

I've figured it's either my memory modules having problems (memtest freezes after the first couple tests) or something with the hard drive. Since I did a reformat of the drive, I'm leaning more towards the memory, although I can't rule out something with the mobo.

Anyone have any insight on what else it could be or have similar experiences?

I see this quoted elsewhere:

Ok, here is something to try.


Find a 600mb or bigger file.

Copy it from one place to another on the same drive.

Now compare the source file to your destination file.

If they are different, your pc is corrupting files when copying etc.

I found out exactly whats causing this... Its the RAM. I put in a different stick alone in different mem slot (eliminate slot contact problem) and found out no more MD5 errors and no corrupted files when copying and comparing.

If MemTest is failing then I would definitely suspect some RAM problem.

Thanks for the reply. I just switched out my memory and unfortunately I'm getting the same error. I also did the copy of a file and both had the same size.

I had this error for a while, then all of a sudden it worked, but then the game I'm trying to install stopped working so I tried uninstalling and reinstalling and now I'm getting the errors again
