White screen of death?

[DemiAjax]

Well, I got my allendale e6300 up to around 2.9 ghz, tested it in orthos for about 45 minutes to an hour, no errors. Bump up FSB to an ambitious 455, doesn't boot. Okay, lower it to 450, now I just get a white screen, can't access bios.
DS3, 3.3, Firestix pc2-1000.
Heeeelp?

Edit: problem may have solved itself. let computer sit for a bit, rebooted, got into bios, lowered fsb to 440, booted at 3115@1.344 V, 44 degrees at idle according to TAT and CoreTemp, time for some stability testing.

don't shoot for a really high fsb, you could do damage to your hardware and you're likely to encounter a lot of errors (which you are). just do it in small increments, like 5mhz at a time, until you error then fine tune it.
