    Doesnt the computer beep multiple times on startup? Also are you using an after market graphics card? (A Card that plugs into a PCI, AGP or PCI-E slot on the motherboard)

Check the cables first, reset the monitor to factory settings. Check also your video card

Your video output is bad. Either the video card, or the onboard video built into the computer. You need to swap out the card or add a card to bypass the built in video port on your computer.

Dell Pc won't boot gets black screen with floating dialog box


Floating dialog box is the monitor's self test. Your monitor tests good. Your computer is the problem.

Computer powers on but monitor, keyboard and mouse are not working


Once the monitor shows "no input", indeed the mouse and keyboard are pretty useless, even if the are working, as you cannot see they are working. If the monitor power light is on or flashing, but nothing displays, borrow a monitor from a friend. If that works, your monitor needs replaced.

Pisplay not shown


Display not shown?

1) Does the monitor show No Signal?
If so go on.

If not;

Use another known to be good monitor, and monitor cable, on your desktop computer. Be aware that the problem may be the monitor cable.

Or use your monitor cable, and monitor, on another KNOWN to be working computer.
The monitor isn't receiving a Video Signal. Means the signal is not reaching the monitor. Could just be a bad monitor cable.

2) If the monitor is good, and the monitor cable is good, the problem is the computer itself. The computer isn't working.

You may see LED lights light up, hear fans running, and maybe even the Harddrive spinning.

Problem could be the Power Supply.

A) IF, all of the LED lights were on at once, they would use less than 1 Watt of power.

B) EACH fan only uses 2 to 3 Watts of power.

C) A typical Processor can use 51 to 125 Watts of power. Just depends on what Processor it is.
(Older Intel Pentium III processors, and AMD Athlon processors, use less power than 51 Watts)

Not enough power? BIOS will not turn the Processor on.

Solution is to test the Power Supply's 3 main voltage power rails, or use another KNOWN to be good, COMPATIBLE power supply, for a test unit.

The 3 main voltage power rails are;

A) 3.3 Volt power rail

B) 5 Volt power rail

C) 12 Volt power rail

Test is done with an economical Multimeter, set to DC Voltage.

Post the model number of the IBM Netvista desktop computer. You will find it on the back of the computer, next to the Windows product key,
(XXXXX-XXXXX-XXXXX-XXXXX-XXXXX), or up on the side of the computer tower.

No monitor or keyboard, fan is loud, Monitor puts up th no input message but wont turn on, keyboard lights are not on either


> fan is loud

When you first turn the computer on, the full runs at 100%, until the motherboard's "POST" (Power On Self Test) procedure has checked all the hardware, and "beeped" the speaker just once.

So, no "beep" (or multiple "beeps") and the 100% speed of the fan suggest a hardware problem with your motherboard.

Take your computer to a qualified technician for professional trouble-shooting.

The spynet watch turns on the but the screen is blank I can hear sounds but can not see the menu screen


When exactly you lost the display?

Just right after turning on the computer?While working in Windows? Or every time you open a program or application?

If problem happened just right after turning on the computer, we have 2 point of failures: Monitor or the VGA CARD/MOBO Onboard.

To test your monitor. While computer and monitor is ON. Unplug the VGA cord at the back or the monitor and check if you will see a box moving across the screen says monitor self test.

If no display replace monitor.

It monitor self test passed. Connect computer to a different monitor and if problem persist then update the video card driver or the motherboard chipset. If all fails then you have to replace your video card or motherboard.

Pls do consider replacing the VGA cord as well.

Hope this helps.

I turn it on and it powers up (the fan comes on), but nothing else comes on. The monitor won't come on, the keyboard does not flash, and I can't hear if the hard drive is doing anything or not.


This is difficult to diagnose without more information, but here are some things you can try.
If you have another monitor, plug that in and see if anything comes up on screen. Unless the motherboard is completely dead, when you turn it on, it should at least flash something (logo, some text, etc).
Check the connection from the power supply to the motherboard. The power supply is the big rectangular shaped box with a lot of wires coming out of it. It is usually gray, and on the outside it has the power plug connector. On newer motherboards the connection for the power supply is a double row rectangular wide plug. ragefuljoe.gif

However, from what you said, it sounds like the motherboard might be dead. The keyboard should blink, and on most motherboards the blink sequence tells you if there is a problem.

How can i tell if my video card needs to be replaced?


Firstly, if you have lost your display, plug another known good monitor into the machine. If that monitor has a display then your own monitor is dead. If you get no display, you need to check if the machine is booting and running. Listen to it when you turn it on, does it beep or make any other noises. A single beep means it has passed the POST (power on self test) so turn on your speakers and see if you can hear anything. You might hear the windows logon sound if you have not changed it. Check to see if the drive lamp is cycling, it should flash fairly constantly but not with any kind of rhythm. If it is a PCI or PCIE video card, with the machine turned off, remove the card and then reinsert it. Sometimes, due to the difference in metals used for connector contacts ( Gold, copper etc) a chemical reaction can take place which causes corrosion and subsequent bad joints, removing and replacing the card remakes the connection. you can also buy or borrow a graphics card and use it if you are using the on-board graphics chip, again, this will show if the machine is running. If the machine halts on errors, you may not get any display at all and this kind of fault requires special gear to locate.

Montior wont turn on


Solid Amber Power LED is indicative of a Motherboard failure. Replace the motherboard.

The GX280 is one of many motherboards made during that time period that may have had capacitors that could fail due to a manufacturing defect if the capacitor. Check the capacitors on the motherboard to see if the tops are popped (there is a X engraved across the top of each capacitor, it the X is open, then the capacitor is bad.)
