The system fan is missing or is not working your system has been halted in order to avoid any dammage your system will power down after 3 seconds for hp vectra vl 420 plz help


If you're referring to the fan on the CPU , and it does not run when you turn on the computer , yes replace it. The system is protecting the CPU from overheating . If you're not sure if the fan is bad , remove the computer access cover to the main board , then , turn the computer on and see if the CPU fan starts to spin. If you notice the fan blades vibrating or jiggling but not spinning , then replace the fan motor assembly .

Hi everyone, I have HP Compaq6910 notebook. The problem is that when it start windows it was too slow. It will take almost 3 minutes to display the Windows loading bar and another 3 minutes to log in to...


Sounds like you have to many startup programs. Check msconfighttp://www.liutilities.com/products/wintaskspro/processlibrary

Don't download or scan anything they ask but it tells what each processor does so you can manually check which ones you obviously don't need and then uncheck them and choose selective startup.

Your boot time will be much faster. Obviously you want all the neccessary startup files to boot so only uncheck the ones you know you don't need at startup.

I think thats why your screen takes so long to boot.

Bios defult to erase system passowrd


You can only change supervisors password in BIOS by entering blans(spacebar) to reomove that password but you cant change your windows password. For that you will have to login with a different user and then delete/change the earlier password. Other repair the OS from its original disc and make sure where you enter the passwords....Do not try to add supervisor password in BIOS, thats very deceptive....sodeep

CPU is locked!


remove the battery from the unit and allow it sit for a couple of minutes then plug in the unit to power and see if it somes up. Removing battery and power often unlocks a unit. make sure hibernation is not causing problem. Once it comes up successfully, power off and reinstall the battery, try again. Some times a failed/failing battery can lock things

Hp vectra vl wont start xp, keeps trying to start over


Could you explain what are you booting from if like you said "no disk drive on this". What was the last thing the member of your family does on that PC? Any new installed programs, or hardware? Does the PC restarts itself after that "full circle" or stays frosen?
