Re: error at start up

Blues, The first thing I would try is to remove and reseat the hard drive. With the laptop oriented with the cover latch towards you the hard drive is on the left of the laptop towards the front end. -Flip the laptop over and locate the hard drive carrier door. -There is one screw holding the drive in place, remove it. - Lift the hard drive door up until you hear a click. -Slide the hard drive out of the computer. -Reinsert the drive and push the hard drive until it is fully seated in the hard drive bay. -Reinstall the retention screw. If that doesn?t work then you either have software corruption problems or hardware failure or both. Let us know if you have any other questions and please don?t forget to rate this post.

Please run setup invalid configuration information

If this error message comes up when you boot up the computer, it means the BIOS requires configuration, usually the Time and Date is wrong.
If this occurs every time you boot up your computer and have changed the Date and Time then this could be caused by a flat BIOS battery.
If so, replace the BIOS battery and then configure the Date and Time and you won't get this error again.

I downloaded this software yesterday but it didn't run on my PC. when i installed, this message appeared on the screen & stop the process of installation. " Error 1904. Module...

Well I would remove all software to that hardware being the TV card. Reboot the pc see if the error regenerates. If not then I would reload the newest version off the manufactures site. As well I would go into the msconfig and tell it not to run on bootup.

Everytime I start up Windows I an error message.

Well, the reason causing Rundll Error is probably that when you are surfing on line, some Trojan and malware attack your PC and modify the registry for malicious purpose. Though the anti-virus and anti-spyware can remove those Trojans and malware, they cann't repair the destroyed registry. So, Rundll Error happens! Of course, Rundll Error is not only caused by Trojans and malware.

Keep getting this message <window

  • "Windows could not start because the following file is missing or corrupt:
    <Windows root>\system32\hal.dll.
    Please re-install a copy of the above file."

  • "<Winnt_root>\System32\Hal.dll missing or corrupt:
    Please re-install a copy of the above file."

  • "Cannot find \Windows\System32\hal.dll"

  • "Cannot find hal.dll"
The "missing or corrupt hal.dll" error displays shortly after the computer is first started. Windows XP has not yet fully loaded when this error message appears. CauseCauses of the "missing or corrupt hal.dll" error include, naturally, a damaged hal.dll DLL file or a hal.dll file that has been deleted or moved from its intended location.Additional causes may include a damaged or missing boot.ini file or possibly a physically damaged hard drive.

    Please let me know you have any further questions or concerns.

Invalid configuration information-please run SETUP program

Here is what you do, go into the BIOS setup, usually you press the DEL key OR F2 or whatever your one is, IT should say on screen as it boots up.... it says "Press YOUR- KEY Key for SETUP". So, get into setup, using your manual ensure it is set correctly. Then SAVE SETTING and exit All should be good now.

My Toshiba Laptop

click Start>>Run>> (type)Msconfig>>Click ok
System configuration utility window will open up
U will see few tabs at the top like General,Startup
Click on startup tab
At the bottom click disable all>>Close>>It will ask for restart
Restart the computer
when the computer restarts you will get the message
You have used the system configuration utility
Check the box at the bottom Do not Show this Message Again and click ok
Now you wont see the icons that use to load up on the right bottom of your system,however they have not been deleted just hidden,if you want to access any of those programmes that use to appear before
Click start>>All Programmes>>and clik the application you need to open.
