Gx620 boots up, then screen goes blank, reboot gives blank screen with cursor blinking. will boot with cd but still shuts down after a minute or two.


Remove the battery and open the case. Look inside the computer with a flashlight to see if any of the capacitors are busted or leaking from corrosion. The capacitors look like little battery towers, but they are not as tall as the AA or AAA batteries.

If the capacitors are bad, your computer goes bunkers.

Hi i forgot my users password an i cant reestart the laptop its a dell laptop windows7 home premium can u help me restart the computer


There are 3 options for your problem:
1. You can boot to WinRE(Windows Recovery Console), run the command prompt. Go to the WINDOWS directory. Rename magnify.exe to magnify.old. Rename cmd.exe to magnify.exe. Restart your computer and boot normally. On the log in screen, click on Ease of Access. Select the option for magnifier. It will open command prompt instead of magnifier. Type the command: control userpasswords2. It will give you the option to reset the password.

2. Run in safe mode. Log in using the profile Administrator. Go to control panel then user accounts. You can change the password of your profile.

3. Dell systems have the built-in factory image restore. It can be found in the WinRE. To go to WinRE, turn system off, power on computer, after pressing the power button, tap on F8 till it gives you a screen that says Advanced Boot Options. Select Repair your Computer. Click on a few things for the language. Then you will have a window that says Windows Recovery Console. Click on Dell Factory Image Restore. Then there you go! it will restore the system back to its factory settings.

Hope this helps!

Screen goes black after 30 mins of working.


There are a few things you need to check here.
1. It could be that your computer power management is set to turn your monitor and harddrive off after 30 to 45 min.

If the computer is however working for 30 to 45 min while you doing stuff and it shuts off, the there is an internal problem "Hardware"

I would suggest you check to see if the power management is set to turn off monitor 30 min and harddrive after 45 min. IF that is not so, then we go on to the next test.

It could possibly be your processor fan is not working so once your processor gets over heated it shuts off the computer.

Turn off the computer, remove the case "this is only if you know what you are doing" with the case off, power on the computer and see if the processor fan is working.

You can get back to me and I can walk you through it.

Hope thiss help.

I had my grandson hook up the router and all seemed to be working fine, but this morning I found I have no phone service. Can you tell me how to remedy the problem. Thanks, Betty Mahoney email: ...


The router has nothing to do with phone service - it's the modem that's plugged into the phone line. Unplug the modem from the phone line. If you don't get phone service back within 30 minutes, use a different phone to report loss of phone service to the phone company. (Depending on the company, it could take up to 30 minutes for the computers to restore service after a short has been removed.)

If that's the case - that unplugging the modem clears it up, call the phone company's internet tech support number.

Hello Richard.
