Try running diagnostics on yourcomputer to see if you have a hardware problem. You should have a CD that camewith the computer that has "Diagnostics and Utilities" listed undercontents. Boot form this CD and run the extended diagnostics.
If you don't have the CD you can go to www.support.dell.com and select "Drivers and Downloads". Enterthe "service tag" (serial number) of the computer. You can then download"Diagnostics" .
To boot from a CD disk, power on your computer and tap the key to bringyou to the "One time boot menu". Insert the CD into the top CD/DVD drive andthen select "Boot from CD/DVD" and hit key. Select the "Runthe 32 Bit Dell Diagnostics.

Every Sony LCD TV comes with VGA port (15 pin D-Sub connector) assuming you have LCD T. You can connect your monitor cable to this port & select the input on TV from the menu.

Unless your pc has a separate video card with an tv (round , black) output there is no way to connect the pc to the tv.

your problem is not clear.

It is possible that the desktop resolution was set too high for the type of monitor you have. This can happen if adjusting screen size settings. If this is the case, you may see the Dell splash screen at boot up and then the screen will go black when trying to load Windows.

If that is the case, try this:
Boot up in Safe mode or VGA mode (Tap F8 a few times when the dell splash screen comes up.....this should open a menu allowing you to choose the different modes)

If you are able to boot up in safe or VGA mode, you should be able to go into the display settings in the control panel and change the resolution. Find out what the native resolution of your monitor is, and see if you can set it to that. otherwise start the slider at the lower settings and gradually work your way up.

Good Luck

sounds like you might have bad memory or most likely a bad processor

you are probably using a usb keyboard....plug in the ps2 keyboard(the round one) and it will pick it up.Some wont have the correct drivers for the usb until it boots. PS2 LOOKS LIKE THE ONE ON THE LEFT AND USB IS ON THE RIGHT.

To remove the message just go to bios, press f2 when you turn on your computer, press enter in boot menu, set first boot in hdd and second boot in cdroom (using + - key)and disable boot from floppy by pressing the space bar
Go to advance and if there is any setting about swap or seek from floppy make it disable

Hope it helps

Apply pressure on the heat sink fan right before you press the power button and continue applying pressure. Watch your screen if you see it boot this means its a problem with your processor clamp that applies pressure to the processor. Try to remove the top part of the clamp. Shouldn't be too hard with some needle nose pliers. Then just replace the heat sink and fan with out that clamp.  

make sure that all the cables are connected to the mother and try the back usb protsor the internal ones

This is fairly vague....
Is the drive formatted properly? Does it work when plugged into another computer? What OS are you running? Does your USB drive require drivers?

code 10 is usualy a driver is not installed,or not installed properly,or has an irq conflict that the system cant resolve.try to download the correct drivers from the dell website and install to see if it resolves.

Check in the power options area of your operating system, and switch off hibernate and switch off sleep, this should prevent the machine powering down.

If you tap your Caps Lock key repeatedly (during the process when you are trying to click F2 and V12)... does your Caps Lock Light turn on and off? If not, your keyboard isn't recognized and may not be plugged in properly.

Try . DEL button of F10 those two should work :)

Please rate my solution :)) Thankyou

Check that batteries are charged and installed properly.--make sure driver disc is installed if applicable- check instructions as some wireless suites need you to push a small connect button to initialise them . Also try shifting the usb conector into another USB port if it is notm getting reconised.

I hope this helps

Sounds like a classic case of overheating. Check the thermal compound under the heatsinks and replace it with Arctic silver 5

Try removing the USB cable to another USB port and see if that helps. Rarely does the keyboard just go bad

Greetings I have the same computer which makes this a little easier I hope for understanding this process even on other computers it is all the same just different messages come up for each and everyone of them. Some go smooth and some just simply get complicated.
First you have to make sure that the disk you have of Windows XP Pro is legal and working it may be a bad disk. The install disk must be working properly. Also do to prior Windows installation which brought you to this point you will have to possibly use a formating program that does a complete erase of your hard drive. I use D/Ban Hardisk Eraser. Click Here
Once downloaded insert the disc into the CD or DVD drive on your computer and do a complete format it may take a while, then go ahead once that process is complete do another install making sure that you are booting from the DVD or CD Rom as your first boot device and the hard drive as the second boot option, under boot order options at the BIOS settings. Most likely this setting is probably already set to do this. If those two things are working the good Windows disk and a clean hard drive for a clean install. You should not have a problem installing the Windows Operating System software. Just follow the on screen directions.
Thanks for using FixYa! cast a vote for me if I assisted you! John

The GX280 line is notorious for having blown capacitors with odd symptoms like those you present here. There are also a couple simpler solutions that might get you going.
1) Verify that you are plugging your monitor into the proper video port, sometimes there is more than 1 and simply switching which port it is on will do it.
The problem with this is that you say that the fan is on high speed, which is an indication that the system is overheating. Generally the fan slows down after a few seconds after turning it on, right?
If that sounds like the issue you can verify it by opening up the tower using the 2 buttons on the short ends of the tower and pulling the top up from the base, it will open like a clamshell. You might need to take the leg/stand holder off which is attached with a thumbscrew on the bottom first.
Once inside, look at the capacitors, the image below will show you what they look like. The top of them, where the K is stamped, should be very flat. If they are bulged or exploded at all this is definitely your issue. If it is, the only real option is the replace the motherboard and given the age of these towers is probably more cost effective to replace the tower as a whole.


Hope this helps!
