Tidus, all may not be lost. If your pc is crashing before Windows loads, then there is unlikely to be a problem with the drives. It is more likely that the BIOS is set to run the system in an incompatible mode, or there is a problem with the memory. First I suggest that you check that the memory is properly seated, unplug it and put it back in. If that doesn't help reset the BIOS to it's defaults (there should be a link on the motherboard to do this), but before you do this it would be a good idea to make a note of your BIOS settings). If none of this helps, check that all the other motherboard components are correctly seated, including the processor. It is also possible that there is a problem with the graphics card, so if you can try a different one that may help you track down the problem.
