Hi guys.. Slight major problem.. I overclocked my AMD Athlon 64 FX-57 the other day it was running at 1600 or 1.6Ghz so I upped the CPU FSB fequency from 200 to 300 and upped the processor voltage from 1.425v to the next one up.. That all rebooted fine and the CPU was showing as running at 2400 or 2.4Ghz as expected.. Now this is a 2.8Ghz processor and looking at overclock reviews people have sucessfully overclocked this processor to 3.0Ghz.. So I wanted to up my power a bit more and I've just done it. I changed the CPU FSB from 300 to 350 which in hindsight would give me my 2800 or 2.8Ghz.. I didn't change the CPU Voltage this time and I saved and exited the bios and the computer rebooted itself.. Now the problem I have is when it rebooted nothings showing on my monitor just a black screen.. All my computers working the fans are goin lights the lot but I have a black screen so I can't even enter bios to revert my changes back to 2.4 Ghz.. Any ideas what's happened and what I can do?

Cheers
mike

clear the cmos and start over.. your fsb speed probably conflicts with your agp multiplier.
