All of a sudden my XPS 430 got frozen every now and then.
I opened up the case, clean all the fan. Then replace the HDD with a Crucial M4 256GB, did a clean installation of Win & 64 bits.
Still freezing once in a while, sometimes when PC was idle.
I thought it was dying RAM - got 2 sticks of Kingston 1333 4GB.
Now the strange thing: It seems to work fine with ONE stick (though I have not tested it for long) but very unstable with 2 sticks (I put them in slot 1 and 3 - white clamps)
With 2 sticks it freeze very often, sometimes could not even boost (froze at Starting Windows stage)
The interesting thing: I ran Memtest on each stick inserted in slot 1 and then in slot 3 - all tests passed no error. But Memtest itself always hangs (frozen) when 2 sticks are installed.
So what is going wrong here?
My BIOS is the older version but I read the description - the new BIOS only gives a new splash logo but nothing else?
