Question about Dell Computers & Internet

I have a Dell Dimension 9150. When I turn the power on the Dell screen comes up and then it goes blank. There are no diagnostic lights on but the power is still on because I can hear the fan inside.

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your ((motherboard to your hard drive)) make sure they have secure dust free connections and are not faulty or just replace them they might be faulty

make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electical extensions


even something as small as an electrical fan and its lead can cause you problems or just replace them they could be faulty a computer needs all electrical power and data to continue through every working device and to have an end so any faulty leads will end up with a computer error


make sure your graphics card is securely seated with no dust built up or in the socket

if you remove your graphics check the socket to make sure its dust free

restart your computer then reinstall it this should activate found new hardware wizard

hope this helps you

SOURCE: My screen goes blank immediately after initial DELL startup image

You can either try to reset the BIOS, or have the restore cd fix it for you. By the way, what does the message say?

SOURCE: I have a Dell Dimension 4600 and it won't boot up.

i would have to disagree with jerry, while that seems reasonable if the motherboard fan isn't running at all then whether or not the video card is ok is somewhat irrelevant.
I would agree somewhat though, i think the PSU might be a good thing to check to see if it is functional.
when you power it on does the CPU fan start or shudder at least ? that would be my first guess for a problem if you had been having any problems recently

It sounds like your dimension 9150 desktop has a primary and secondary drive.now when you say it wont start up what are you referring too?does it not power on at all, do any of the fans or lights come on. and also sounds like you got an external hard drive. now I got confused when you explained when it reads the drive windows says it cant read the drive. My question is I thought the pc would not start up? can you explain little more in detail, so i can try and give you the right advice?

I want to restore my dell dimension 9150 to factory settings can u help


If you were using Windows Xp just press Ctrl + F11 when you turn on your computer.

Press F8 if you were using Windows Vista then select repair your computer from the list.

Then if you have any disk or any Operating System disk insert the disk then boot from CD and follow the on screen instructions.

Hope it helps you....:)

Yes you can. Your best is to use the largest and best ram in the number one slot. I would remove ALL the ram and start with the 2 gig in the first slot - then add others until you get the error message - remove that one and keep the rest.

Lights 3 &4 stay on.


Computer beeping at you is usually a problem with the video card or memory. Try re-seating both and see if you still have the same problem. If you do, individually remove each component and power on to test if the beeps persist.
