My Main System is Dead...

As the title says my main system is dead. I was working on it earlier, went to get some dinner and came back later to find it powered down. Hit the power button and it never POSTed Stripped it down sequentially until I was left with just the CPU plugged into the main board and I still don’t even get any beeps! It is a Gigabyte GA-K8NS Pro motherboard and has never been quite right so I am tempted to think it is that, but there is also the possibility of graphics, RAM and CPU issues. Until I get some cash and figure out what went I won’t be doing much development as that box housed all of my work including Gentoo CVS repos, experimental ebuilds and such. I think the hard drive is intact but don’t have any other SATA systems. Pretty sure I also have a DVD backup from about a month or so ago, but my first priority is to get the system working again. If anyone feels like sharing any tips with me on diagnosing my system I would welcome them. It has been a crappy week - at least I have my new laptop so I can still get some work done. Most of my data and SVN repos are on that box too though Update: It does seem to be the time for system problems with quite a few devs having trouble with their systems in the last few months. Checking on my mainboard (pretty sure it is that - hunch though) it is three weeks out of warranty. Not a good week at all - can’t get anything done until I get my system working again…
