I wouldn't be so quick to call that machine dead. It sounds like something else is causing problems or a combination of multiple problems.
When I run into something like this that I can't figure out I go straight to the basics. Remove all third party cards, devices, ram, etc. Pull all the hard drives. Put factory ram back in or just 2 sticks in and test. Boot from an external that you know works in other machines, or from an OS installer on a flash drive. If it boots to the flash drive take the next step and install a hard drive. Repartition and wipe it and try and do an OS install. If it crashes on the OS install swap the two sticks of ram with two others or try a different hard drive that you are absolutely certain is working. You just need to run through methodically testing parts to see what makes a difference.
