6 months old pc, random freezes even in BIOS!

 southernpride -
Hey people,

here's my deal. i have bought a new system months ago. (we sat and chose the partials one by one, with a few friends who know about computers)
it has never been all fine and since the place we bought the computer has a crappy "support", i have always tried to figure out the problems by my own. but now, i'm done...

my system uses windows 7.
i use ASUS m4n68t-m motherboard
AMD ATHLON 2 X4 Processor (2,9 ghz)
Kingston 1 GB DDR3 Ram
and sapphire hd4650 graphics card

the ways i tried to fix the problem;
-i've done a memtest and it turned out all clean
-i have checked the DRAM Voltage valuse from qualified vendor list of Asus, it said 1.5 Voltage, i've tried several voltages. (from 1.5 to 1.7)
-i had checked the disk with chkdsk tool.
-i have updated my motherboard's and my graphic card's driver.
-i have checked the event viewer and it told that my problem is about northbridge configuration.(northbridge error...)
Component: AMD Northbridge
Error Source: Machine Check Exception
Error Type: CRC Error
Processor ID: 0
-i have updated the BIOS

so, anything else i can do on this? or should i just go and ask about the guarantee? or, do any of you have any kind of idea about what my problematic component is :(

thanx a lot.
