Hi All, (sorry to post this message here & on device drivers, I realize this forum will be more suitable for this post...) I bought a new Dell Inspiron 1420 with the following specifications : Intel® Core™2 Duo mobile processor T5750, 3GB DDR2, 250GB HD. When loading vista I get this error with no ability to solve this issue whatsoever. the error message number is 0x0000124, which I see other people posted threads about too, but I can't get any usable information which can help me solve my problem. I tried re-installing vista, downgrading to XP, updating the bios, updating the drivers. Went through Dell's customer care's support personnel without any luck. In addition, I ran all the diagnostics software that came with the laptop - there's a pre-loaded software that checks all the devices and memory, and to be done with I ran windows memory diagnostic. All the diagnostic software came with nothing - all tests passed and all came up with nothing. I have some dump files which I don't know how to process. Can anyone help me shed some light on this issue ? Could it be a hardware problem, what is more likely (motherboard, other peripherial ?) *** Edited *** I parsed the dump file and got the following output : WHEA_UNCORRECTABLE_ERROR (124) A fatal hardware error has occurred.
