Hi all,
Recently I purchased several components for a new rig, which when running I am extremely pleased with. However, I've a niggling problem. Which means if I boot from cold, the computer hangs and needs to be restarted again via the power button. On the second or third (possibly more) repress the PC boots into life.

Initially I thought it was a problem related to the mobo looking for a pci card instead of a pci-e card, as seen here: http://forums.overclockers.co.uk/showthread.php?t=17874825

However the problem of not booting first time from cold, continues.
My rig is this:
Intel Core 2 Quad Pro Q6600
Abit IX38 QuadGT Intel X38
Corsair 2GB DDR2 XMS2-6400C4 TwinX
HIS Radeon 3850
LG DVD RW
Maxtor 250 g sata drives (x2 in RAID1)
Tagan 480 w psu (approx 3 years old)

The graphics card is OC'd to near 3870 speeds but the cpu is stock (until I get this booting issue resolved). The PSU was until recently powering a P4 -D system with the same graphics card, same hdd and dvd drive. In fact, once booted up, this seems rock solid, so I am disinclined to think it's the psu.

When booting up from cold, the POST code reads 9.9. as I tend to shut down my pc fully. When it fails to boot, it gets as far as 9.0. which I believe means abit guru initialised BIOS taking over... except it doesn't.

Any suggestions please. Is my psu on the way out? Is it the mobo - time for RMA? I've checked all the connectors...

When it finally boots, i get a message ACHI BIOS not installed. Is this somethingto be concerned about?

Thanks for reading this rather long post. And for any response(s).

Chris
 
From a stab at this it does sound as though it is the motherboard.

Have you tried flashing your BIOS to a different revision?
 
Kinda, checked it's the latest one available. Haven't rolled it back to a previous version. Though it looks like there are only three available for this board.
 
May be worth at least trying it, although from experience unfortunately most times this happens it results in a RMA. :(
 
Boo. I'll try rolling back the BIOS to the previous versions. Thanks Yewen for the advice. Chris
