Well then ... lost my bottle on trying to boot out of case ; so instead took new board out both to check for any rogue standouts and to try it in my old case/PSU setup. Same problem ; runs for very short time and stops. New case/PSU setup booted my old board fine so it's down to board ; CPU or maybe both. Cooler maybe isn't totally certified ; but I chose it based on it being part of a bundle I saw at an online computer retailer so someone else must think it's OK! I'm not out of the woods yet but I can at least see some light ; would like to thank everyone sincerely for their input here ; it really has helped.
So back to business ; how much is my bike worth and is it a Zasker?
