Long boot-up time even with an SSD (due to long POST?)

Hi

I installed Windows 7 on my SSD to reduce boot times. I'm at about 23 seconds now. I know a lot of people who have it under 10 seconds. Some have told me that Windows 8 will reduce it further but from what I see only about 10 of those 23 seconds is loading Windows. The POST seems likes its taking far too long.

I'm using an ASUS P8Z77-V LX motherboard, with Windows 7 installed on a Samsung 840 250GB SSD in AHCI mode. I've updated the BIOS to the most recent.

Any ideas as to why the POST is taking too long ( if it is?) and anything else I can do to improve boot speeds?

Thanks in advance for your answers.

If you have a lot of USB devices plugged in, you could check to see if the BIOS initializes all of them on start up. By default (if the option is there) I think it is only on partial (mouse + keyboard), but if it's set for full then it might take extra time to initialize a lot of USB devices.

Yes it was a clean install. I didn't follow a guide but reading over that it seems like I did most of those steps. I may try re-installing if I can't find any other solutions.

It's your motherboard. It obviously needs long time during POST to initialize some components. 13 seconds of POST for a motherboard with UEFI BIOS is way too long. I've seen some boards do the POST in 2 seconds, but this also depends on exact hardware configuration. You can try disabling all onboard components (onboard graphics if present, onboard LAN, onboard audio, serial and parallel ports) and try again. Also, if you are using several memory sticks, remove all but 1 and try again. This obviously isn't the permament and satisfying solution, but at least you'll figure out the exact component that is responsible for your mobo's long POST. Disconnecting unnecessary USB devices may also help. As a final measure, you can also try using only SATA2 ports and disable SATA3.

EDIT: Almost forgot, go to BIOS and try to find any option related to boot, such as fast boot or something similar. Most UEFI motherboards have this option, so try enabling it if it is disabled. You can also try disabling memory checks and other hardware checks if such options are available.
