Hi everyone:

It makes me feel like a complete noob to start a thread like this but I think my problem with this motherboard is quite unusual and it isn't those common "NO BOOT after BIOS Flash" that we all got sick and tired of reading everyday...

First of all, let's skip all those common assumption like
1. cables fully plugged in?
2. Rams properly seated?
3. Ram defective? (Ran Memtest/Orthos blend prior BIOS flash and were FREE of errors.)
4. Video card related issues? (it was working perfectly fine, PCI-E 6pin plugged)
Etc, etc...

System Specs: Ram Highlight - 2x1GB Crucial Ballistix 8500. For the rest, please check my signature.
Flash Method: USB drive and EZ Flash under BIOS

The P5K-DLX came with 0123 bios originally. As usual, I always flash the BIOS ONE by ONE.

1. ~ I began updating the the BIOS to 0202 and the flash went well during the process. System auto reboots after successful flash. System booted up fine. Screen shows the usual F1 to enter setup or F2 to load default and continue and again I hit F1 as usual, entered BIOS, hit load to default. System shuts down and restarted, now this is the point where I get BLACK SCREEN.

No problem, I turned the system off and shuts down the PSU, unplugged it for 30 secs. DONE THE CLEAR CMOS procedures PROPERLY (I had a millions times of SUCCESSFUL experience with this, no doubt about that, this is my 6th mobo). I turn the system on again, it BOOTED and POSTED fine and NO black screen. As usual, hit F1 and went into BIOS. Hit Load default, Save and exit. System booted up fine but again I see the black screen. Shuts the system off, turn off the PSU, wait 30 secs, turn them back on, and booted&posted fine. Got the Overclocked failed...blah blah...I then again entered the BIOS and DIDN'T change anything but go straight to load default AGAIN...this time I DID NOT GET the BLACK SCREEN. and I DID NOT GET the Overclock Failed...

So I thought it went ok there, but it wasn't. I want to make sure it does reboot ok. I didn't change anything and go straight to save and exit. NOW I GOT the black screen again...

OK, not to panic here, I shut down the system, off the PSU, turn it back on, it booted/posted fine, got the Overclock failed msg again.. entered BIOS hit Load Default save and exit, booted/posted fine, entered BIOS and thought, it may be that 0202 is still an older BIOS so I used EZflash again to continue update BIOS to the newest official BIOS - 0311

EXACTLY done the same way as from 0123 to 0202. I got the Black Screen after save and exit without changing anything. DID the CMOS clear AGAIN...waited for 5 mins...and it's still happening with the LOOOOOOOONG weird sometimes black screen problem.

OK and becouse I'm not a noob so I know the "overclock failed msg meant something " I bumped the ram voltage to 2.2v, divider set to DDRII800, 5-5-5-15 timings, the new 0311 BIOS has 1T/2T option and of course I selected 2T, CPU voltage...NB voltage...all adjusted as usual....and STILL having this werid bad sometimes no screen cycle.

I know the flash went successfully and I can go into windows and stresstest everything NO ERROR, everything seems stable but if I go into BIOS and hit save and exit or load to default...I'll get no screen crap.

I tried to troubleshoot the problem but to no avail, if you know the possible adjustment(s) under BIOS to remedy this, please make a reply here.
