Oh dear.... my new PC won't POST :(
I have been pretty happy with my new E4300 P5B Deluxe system and had it OC'd to 350 FSB where it was stable at 1.4Vcore. Because I wanted to get the most out of my 800MHz RAM, I thought I'd try lowering the multiplier from 9x to 8x, and then upping the FSB to 400. This worked OK and so I thought I'd try a bit further - 415 worked OK too, but when I upped it to 420 it POSTED and booted OK but then the system shut-down after about 5-10 seconds of Orthos.
Now when I start the machine, the fans start but after about 5 seconds it shuts off automatically for a couple of seconds and then restarts automatically and stays powered on with fans but nothing happens.
It doesn't beep and it doesn't POST. The monitor does not get any signal (ie. light stays amber)
I have tried removing the battery and clearing the BIOS for about 10 seconds which didn't work, so I tried clearing it for 2 hours including removing the 2 x RAM sticks and that also didn't help (I did try each RAM stick individually). :(
I will now leave it clearing overnight to see if that solves the problem. However, in case it doesn\'t I wanted to see how I should go about determining what\'s gone wrong, so I can RMA the correct part.
All the parts are new, and I only have a laptop so it\'s a bit difficult testing each component in a new machine, hence the request for ideas on determining which component is dead.
I may be able to borrow someone else\'s machine to try the components, but that is not a definite possibility.
Help! :(
