here are the specs:
Intel Q8300 CPU
8GB RAM (patroit memory-500mhz)
ATI RADEON HD 5450
the problem is if i overclock the fsb (even just to 340), it refuses to boot. it powers on, and you can here the dvd + hdd spin, but the activity light stays off. also, when at stock 2.5ghz, it has a tendency to 'cut out,' which has the same problems as OC'ing it.
another thing is it takes 2 attempts to boot. i push the power button, it starts for about 1/2 a second, the shuts down, then 4 seconds later it boots, but with probs mentioned.
If it was a dual I'd say upping the FSB to 400 was possible.
With a Quad it might crash at 334.
I think your motherboard is screwed. Its time for a new system kid.
EDIT - I forgot to mention - the Q8xxx series was a bit of a dud. Dunno what Intel were doing there. Didn't matter though, they could've derp'd for the last 4 years and Clock for Clock still been the fastest with the Q9xxx
Its not worth spending any money on old stuff, a decent LGA775 mobo will set you back as much as a good value Z68. DDR3 RAM is extremely cheap and a Core i3 2100 will make your Q8300 look like a snail.
