Hi guys
I have an older PC build from a few years back (I didn't build) that has an ASUS Sabertooth 55i mobo. I've been trying to resurrect this thing to working state, but I'm constantly hit with the same problem, which others have also described having on the ASUS forums:
It won't post, but everything comes on as normal, LED lights blink back and forth for CPU and RAM check, then the VGA light goes on and stays on. Nothing on the monitor. This would lead one to believe it is a graphics card issue, right? Well, here's what I've tried, recommended by others:
Switched out graphics card with two other spare cards, same exact error (used two cards with additional 6-pin power, one old card without any extra power)
Tried installing GPUs in second slot, same error
Cleared CMOS (multiple ways)
Unplugged the 8-pin power from mobo and switched to 4-pin, as recommended by some users, still boots the same
Unplugged all drives, nothing
Other recommendations I have read about this issue: maybe a bad PSU (though everything seems to be fine) - I don't have a good spare to check this; maybe CPU is not compatible with the version of BIOS (it's an i3-550, but I have no idea what version of BIOS the board has, besides what's on the outside... Rev 1.02G (which would NOT be compatible with the CPU, apparently). OR, could just be that the board went bad!
It's frustrating because everything else seems fine. Hard disk spins up, all fans running (yes, even on the graphics cards). Looking for any further suggestions on this from anyone who may have dealt with this particular mobo.
One more thing: I know that this board gives error beeps from the external speaker which can help further identify the issue, but I don't get any beeps because there's no external speaker.
I may have to swipe one from another build later.
