The thing that impresses me here is how good the open-source Intel drivers are, in performance, at least.
The Llano part is stronger in terms of hardware, so you'd expect the proprietary AMD driver to be able to pull out wins, since presumably that driver is about as optimized as it can get. The HD4000 gives it a decent run however (by which I mean performs at least 50% as fast). In fact, looking at the hardware capabilities, Llano beats the HD4000 by about what you'd expect, given perfect drivers.
So with Intel we have company whose open graphics drivers are as good as those developed with a proprietary driver model, which is very nice to see.
(For those complaining that the linux version of Catalyst is crap, in performance terms it generally isn't. Stability is another issue. I'm basing my comments above of the performance of the HD4000 vs Catalyst under *both* linux and Windows.)
Mobo model? Any BIOS beeps? Checked all connections? Checked for blown capacitors? Tried reflowing the board?
It's an MSI 7345 Neo 2.
Hmm, according to the user manual, the LED's lighting up indicate the CPU is damaged or not installed properly.
It's a little weird because the power button no longer does a hard reset and some of the fans seem to be spinning up and down at random intervals, so i assumed it was a MB or power issue, but i guess i'll try fiddling around with the CPU a bit. I'm not hopeful though.
Now i'm going to die of dust inhalation.
I have run this machine 24x7 for about 4.5 years now, never turning it off. So i did get a fair amount of time out of it.
Edit: It's the fan inside the power supply unit itself that is spinning up and down, and I've seen both it and the case fans stop spinning completely for short times, so I'm pretty sure it's the power supply that's gone bad. It must not be properly supplying the CPU or some section of the mobo which is what's causing those LED's to light up.

It should be easy to use a different PSU to try...
Sure, but then i run the risk of wasting $50 and it still doesn't work. And i don't particularly care about extending the life of this machine since it's getting old, so I figure i might as well just buy a new machine now.
I'm halfway tempted to wait a few weeks for Trinity to come out to see if it forces Intel to lower prices, but I'm doubting it will actually be a faster CPU and I'm not too worried about the money so I think i'll just go for it now.
