Just got Asus A8N-SLI - Slow Bios Post

So I just installed my Asus A8N-SLI mobo, and was anticipating the intense speed I was about to witness. To my horror, the Asus bios splash screen sat there for like 30 seconds, untill the boot process finally kicked in.

I checked that quick boot was enabled, and then disbaled the splash screen. After this I rebooted, and it was still slow as molasses, detecting the drives, and what not. What could possibly wrong. I am now installing windows, and everything seems fine except for the heinous bios post.

 
Slow POST is usually a power supply issue, or a corrupt CMOS. Whatcha got feedin' the juice?

Also, might want to try clearing the CMOS (the real way - remove the battery and switch the jumper - see your manual) and see if that does anything for you.
 
Just tried popping the battery out, and unplugging the power plug. It's still doing it. I tried disabling a bunch things likes SATA, and on board sound, but it didn't help either.

I have a 380watt power supply which has been working great for me for 2 years. This is puzzling.
 
Note that there is a brand new bios for the A8N-SLI. You can get it here.

Try installing the new BIOS first.

Note also that according to page 1-25 of the updated manual, your two-year old 380 Watt power supply is barely above the PSU requirement for a "light" load on the A8N-SLI. Since I don't know the brand of PSU you have, the peak wattage claim might be suspect anyway.

I would also be extremely reluctant to power the A8N-SLI with a two year old PSU. You're probably going to have to use the 24-pin ATX Power connector adapter (which is going to further reduce your watts going to the motherboard anyway), and there is no way that PSU was designed to power PCI-express or the SATA 3Gb/s controllers that the A8N-SLI sports. In any event, if you hope to eventually power an SLI setup (which I assume is why you bought the A8N-SLI in the first place), that PSU is going to fry.

Let's assume for the moment it's not the PSU. Try installing the new bios, clear CMOS, and try booting up with only the hard drive (non-SATA would be preferable) and let us know what happens.

Please also include your current configuration in your next post, it will make a diagnosis easier. It's the basic ASUS A8N-SLI, not the deluxe or the new premium right?

I'm going to buy the same board myself next week, so I'm very interested in helping you get the problem solved.

 
Thanks for the replies guys. Here is my setup:

A8N-SLI Deluxe
EVGA 6600GT 128meg
2 512 sticks of micron
200GB Western digital
Sound Blaster Audigy Platinum 2
380watt - not sure brand

I think you might be right about the power supply. I keep playing around, and keep you guys posted. Thanks.
 
What's your CPU? The CPU is probably your biggest consumer of watts--particularly the AMD FX series. Other than that, your system looks relatively low consumption. Still, I'm betting on the PSU as the cause of your problems.

Did you install the new BIOS?
 
Like everyone else has said, that PSU is probably crap-tastic. If you don't even know what brand it is, and its not labeled then its instant crap. I would go buy a 500-watt plus, and as Woofmeister said - make sure you have the latest BIOS
 
I got it working!!!!!!

I read some other peopl having slow boot ups with a Western Digital and other motherboards. The problem is that I had the drive set to master on the channel by itself. I set it now to cable select, and it's not working perfectly. Thanks everyone, and I hope this helps others that have the same issue.

I don't know that 500 watts is neccesary for his system (would leave plenty of futureproofing for upgrades), but I'd want at least 400 watts from a quality manufacturer.

Good to hear it! Wish me luck on my build.
 
You may also want to get to the BIOS, then:

select the "Boot" tab

then click "Boot Settings Configuration"

and enable "Quick Boot"
