Did a bios flash and computer started went through boot up but now freezes on logo page will not continue on ?

Your hard drive may have gone south. Remove it and check with diagnostic software. Bad sectors in critical areas of operating system data will do this.

Try tapping the F12 key during boot. That should bring up a menu of bootable devices. Select the floppy drive.
You can also change the boot order in the BIOS.

Make *absolutely sure* you are plugged in when you flash the BIOS!

Start and let it boot again and press F8 immediatly and use SAFE MODE to boot,
let the Desktop come up,
once stable shut down and wait for 3 - 4 mins
restart

The little "stack of CD's" is a hard disk activity light.
In an ACER, if it blinks on boot, you may need to pop the PC open and bridge the BIOS jumper to reset the BIOS... Not fun nor easy, but possible.

Because you didn't state you added RAM, changed a BIOS setting, etc, we'll continue as a regular user:

First to check:
When you power on, do you get a BIOS screen? Meaning quick text showing pc info, RAM, or a splash screen (picture) saying the manufacturer, HP, Acer, ASUS, Toshiba, etc... Can you tap F2 (Acer), F10 (HP/Compaq) and enter the BIOS?

If NO,
your motherboard may be to blame, the timing of the flashing lights indicating an error, or your hard disk has died and a poor BIOS could not translate that error to the user in text format.

If YES,
Does it continue on to show a Microsoft Windows Logo, or logo depecting your operating system (os), Ubuntu, Xandros, etc?

If NO: your hard disk may be failing, physically loose, completely dead, OR your os may be corrupted. You can unplug it, pull the battery, hold power on for 10 sec, flip it over, unscrew the hard drive cover, re-seat the hard disk (pull it out, put it back). Repeat for the RAM. Add the battery, plug it in and retry.

If YES,
And the pc starts loading Windows, Ubuntu, etc, but HANGS with the hard drive light flashing, you may have a simple driver conflict issue. You can try repeatedly tapping F8 while booting and select "last known good configuration" (windows only). It may help, or you may need help.

:) Sorry!

you need a bootable image on your flash drive. if you ve just copied the cd files the USB wont do a thing and the monitor will keep blinking. what is the exact problem?

enter to bios set up then disable the f1 and f2

Before trying to use any of Dell-net's suggestions, we've got to get you into the bios.

It looks generally like this:



You should see a message displayed when you start the computer that says press "Del or F2 or F10" to enter setup.

Once we get here, we can proceed.

Hello,

The EPA logo and the Fullscreen logo all are stored in the bios. That is the update  you download from the manufacturer's website contains both the logos in it. So if you mod the bios update and then apply the patch the next time when you boot your computer you will see the new logo.

***BEWARE A BAD FLASH CAN RENDER YOUR MOTHERBOARD USELESS****

Software Used

Winflash 1.51 : ftp://ftp.ecs.com.tw/driver/bios/flash/winflash151.exe
Award Bios Editor 1.0 : http://sourceforge.net/projects/awdbedit/
CBROM 2.15 : http://www.biosmods.com/download/award/cbrom215.zip



The mods are in two sections.  If you only want one or the other, just skip to that section.

FULLSCREEN LOGO

1. Make Sure the motherboard uses the Award Bios.

2. Either Download the new Bios from the Manufacturer website or get it from the system Bios directly by backing it up.  For backing up and updating bios, I use WinFlash 1.51 (there might be a newer version, I just stick with what works!).

3. Now we have the bios file on disk. Now make a new bitmap image with any of your favorite imaging software. Make sure that the final bitmap image you have created is 640*480 and 256 colors.

4. Now use the CBROM Utility to change the boot logo in the bios file.
This is done by using Command Prompt

c:\bios>CBROM215 bios.bin /logo logo.bmp

5. Now to check whether the bios file was updated correctly. Run the Award bios editor. (make sure the dlls in the plugin directory are moved to the folder with awbedit.exe)

6. Load the bios.bin in the Award bios editor and check in the left hand list for Fullscreen Logo and that it does show your logo.  If okay your bios is now ready to be flashed.

7. Now use Winflash utility, load the bios.bin and click on update .

8. Reboot the computer and the bios logo is changed.


EPA Logo:

Procedure for the EPA logo is just same except the few things.

Image size is : 138*84 16 Colors and 72 pixels/inch

Command for adding to bios file is : c:\bios>CBROM215 bios.bin /epa epalogo.bmp

When you check for the EPA logo in the Award Bios Editor, the colors will not be same as those that you choose but when you flash the bios and reboot, it will show the original colors.


*****PRECAUTIONS*****

Never try to flash bios without a uninterruptible power supply (UPS).
Close all the programs before flashing from Windows.
ALWAYS wait for flash program to notify you for reboot, DO NOT EVER EVER reboot when you think it is ready or taking too long.  Mucking up the flash CAN MAKE YOUR MOTHERBOARD GARBAGE!!!  You have been warned!!

I hope that this helps,
Ken

I would first attempt to reinstall the software from the install cd. Your Toshiba support page is recomending a new BIOS upgrade. See below:
