Hello again,

I've been having this problem now, and it's starting to bug me more and more...

For some reason, every time I turn on my pc, it will freeze BEFORE the POST screen... right after pressing the power button (and waiting a while for the triple head to change resolutions) ... all the screen shows is a little white dash on the top left corner... frozen, not flashing like it should

So, I hit the reset button, and it boots normally... it's very weird.

This happens every time I turn the pc on from cold... and occasionally on a reboot too... always, hitting the reset button will produce a successful second-try boot

I suspect it's a hardware thing... since a problem this early on the booting process can't possibly be related to any software configuration... it could also be some kink in the BIOS Tongue

I tried waiting a while after turning on the power stabilizers to press the power button... to allow the PSU time to charge up the capacitors or something... didn't work... still weird.

Any thoughts?

Cheers

Being so early in the boot it can only come down to a handful of things like the board, cpu, ram and psu. Try booting with a single stick of ram, and switch the stick if it still has the error. The ponly way to test the other things is to get your hands on a spare PSU, CPU or motherboard. Have you tried flashing to a newer BIOS?

This may be the dreaded Cold Boot bug.. I have seen this on Asus motherboard when the board is clocked but never when they are running default settings and read about it many times over the years from others.

I would verify stable voltages however I would not assume you have bad components.. this is actually something that is known and has been around for quite some time. I had it on 2 boards in the past.. one was Intel and the other AMD whereby certain clock settings would force me to boot the system twice.

I can not say for sure that is what you are experiencing however if after you verify everything looks good and nothing appears unstable and this only occurs with a clock on the system then it probably is the cold boot bug

Now, I did read at one time someone had to return their P6T because of a power switch defect on the motherboard. They were having problems getting the board to start and then it simply stopped working from the power button but they could hit the reset and it would boot.. something completely different.

If you are not clocking the system then I would indeed suspect a component at that point
