It could be somethinglike not having enough vcore, having too much vcore, incorrect ram timings, not enough vdimm, too high of a fsb setting, or any number of other settings. The display problem really isn't the problem, just a symptom. There is no monitor problem. If you have a speaker connected to the motherboard (not in the back but a case speaker connected directly to the mobo by the power on switch wires) it should beep once when it posts. If it doesn't beep at all then you know it didn't post. It's also quite possible that it will beep multiple times in one pattern or another that will tell you what type of failure you are having.
The beeps is exactly how I got to know it was an issue with the ATI card not powering up, which prevented bios to post and thus not turning on my monitor. After reading some on the ATI forums I discovered there were some others having the same issue with a 57xx or 58xx type ATI, with a 4-pin PCI-E connector.
I also got the overclock failed press F1 blabla after post, so I loaded defaults but the issue kept on returning, without any oc.
So I borrowed a NVIDIA card from a friend for a couple of weeks (a HEAVIER ONE), and it didn't happen once. So I knew in one blow it wasn't the PSU either.
Even now, every time I do a cold boot, the pc switches off after a few seconds, and powers on again without making POST and the monitor stays off. after that, turning the PSU power switch off and on again, it finally posts, with or without a IBT 50runs and prime95 24h stable oc. When not oc'ed though the issue is LESS frequent. In my case it IS the damned ATI card, and his issue sounded exactly the same to me, and I noticed he had a similar ATI card, so I drew a conclusion.
If he experiences the same wacky stuff when cold booting, like the pc turning off and on again on its own while the monitor stays off/no post, he should definitely look into this, and at least borrow an NVIDIA or something from someone to test this out and try and oc again then. I'll bet with an nvidia, he will see the issue vanish without a trace.
