Hallo Seyyed,

Before anybody starts arguing that I don't have 64-bit, this is uname -r and
uname -m:
root@n03:~# uname -r
2.6.32-3-amd64
root@n03:~# uname -m
x86_64

I have a similar problem on a computer I bought a few years ago and only
recently found that the cause might be a buggy bios.

I don't have 48Gb ram but only 4Gb and can use about 3.3Gb of it.

Johann

Both of you: Have you tried booting from a live disk for a different distro. I'd suggest something really different, like Fedora or OpenSUSE, and not one based on Debian.

I did try Ubuntu 12.04 rescue remix, and it behaved exactly the same. I used to use Fedora but switched to Debian some time ago - I will try CentOS later.

An update on the RAM, I did test each dimm and all passed a quick memtest.

Ubuntu is based on Debian and may have the same bug(s). CentOS would be a good test since it comes from an entirely different chain.
