PC takes too long to bios POST.

topic says it all. i have corsair tx650w. and I don't know if the psu causes this phenomena

Make sure to go through the bios and turn off any and all features you aren't using...

Things like PXE boot, and any other boot features. Turn off any parallel and serial ports, and make sure your boot order and drive order are all set correctly and you don't have any extra boot processes...

Many times its the bios searching for things that aren't there that makes the post go so long...

 

[4hya]

actually. the post process is quick. i'll upload a video of the problem

 

[4hya]

the time before the cpu sends signal to the monitor is what is slow. after sending the signal. it starts the post process

The BIOS checks all the devices. If you have a lot of gear hanging off the ports, it is liable to be slow. For a test, disconnect everything (not the mouse and keyboard of course) and see whether that helps.

i've tested it with no avail. removed everything. even the hdds.

Hmm, then there is another problem. Don't know. Maybe a BIOS update helps - if a newer version is available from the manufaturer of the board.

The order that things happen is important. A more detailed description of your symptoms would help.

Is this a laptop? The Post - Boot - Startup procedure is slightly different in a laptop than a desktop.

In a modern laptop the sequences are normally:

1. Push the power button
2. A black screen with a small flat curser appears in the upper left corner of the screen for a very short time.
3. A "Splash Screen" appears with the Brand Logo of the laptop and a message at the bottom instructing you how to get into the BIOS settings.
4. The screen goes dark again for a second or two, the small flat curser appears in the upper left corner of the screen and blinks a couple of times.
5. The "Starting Windows" message appears.

Where in this sequence does your, I'm assuming laptop, freeze and delay?

as you can see in this video.

it takes too long for the pc to show the POST screen.

I am OC'ing this system.. but I've tried this with the default BIOS settings. and even flashed the new BIOS version

 

[4hya]

sometimes it's fast... but most of the time..it's like in the video... even on restarts

That is slow to POST, you got that right.

I would suspect the power supply first. Can you get your hands on another to test with?

And, crazy as it sounds, you might want to check the 3 volt battery on the motherboard. Some strange things happen when they get weak.

That is slow to POST, you got that right.

Abnormally slow, even for an Asus board.

Has it been happening since day one, or since you upgraded something? ie the PSU?

 

[4hya]

yes. it is abnormally slow.

I've removed the internal speaker. the problem seams to be solved. but still. I don't want to presume that the speaker is the problem.. I'll be observing for three more days. I'll post the results.

 

[4hya]

my pc seams to be fixed. thread solved

 

[TVeblen]

Just curious: Was this a case speaker that you connected to a header on the motherboard?
Or was this an internal speaker on the motherboard?

 

[4hya]

this one.
