Doesn't turn on (power), or will not display anything?

Bad memory chips will cause the display to be inoperable.
I once put PC-2700 chips in a laptop that would only take PC-2100. The chips I received were wrong, but I didn't check before installng them. Anyway, it worked like a champ for about 5 mo. Then the display went out. I could tell that the computer was still operating, so I sent it back for warranty repair. Of course, the chips were aftermarket, so it wasn't covered under warranty, but that was the problem.

Acer ax3400g does not boot and light blinks twice

Either your memory, lcd monitor or the video card is bad.

Check the Memory by steps below:

Remove the Power Cord, Open the Case and remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.
I'm thinking that it might be your monitor because if the monitor was working and the video card was bad, you would get a No Signal message appearing on your screen.
Try another monitor on the computer. Borrow a monitor from a friend, family member, neighbor or co-worker and see if it works. If it does then your monitor needs to be replaced. If it does not work, then you've got a video card issue.

Check Video Card below:
If nothing ever posts to the screen then more than likely your video card is bad. Go purchase a Video Card that will fit into one of your open PCI Slots.

So the fan is running, what about the hard drive? Do you hear the hard drive spinning?
If it looks like it booted all the way except the display is blank try the steps below.

Shine a flashlight on the dark screen to see if you barely see the icons on the desktop. If so, then the LCD Inverter is bad.

Plug in an external monitor and see if the display shows up on it. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If so that proves your video card is ok. The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

If you see no icons by shinning a flash light and the external monitor works, then your screen is bad. If you see no icons by shinning the flash light and nothing shows on the external monitor, then most likely your video card is bad.
If you don't think the system booted all the way then try the steps below.
Beep tones and blinking lights tells the technicians what is going on with the laptop and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous. Most times the problem is with the memory or Video Card. Count the Blinking Lights or Beeps and take note of their pattern (1 Long or 1 Long followed by 2 Short).

Maybe your memory is bad or the memory slot is bad.

Remove the Power Cord, Open the Case and remove one of the memory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and try rebooting. If it fails take the chip out and set it aside, then put the other chip in and try booting it in both slots. If it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting.

I purchased 2 GB chips to try to increase the speed of my desktop. After putting in the chips my computer won't boot back up, my monitor is black and the computer is making a constant beeping nois

OK. First, I'm assuming that you have a Dell Vostro 200 as per the topic title. That said, you machine has a maximum memory capacity of 4GB. So, if you added the 2 - 2GB DIMMS in slots 3 and 4, leaving your original memory in the machine, you will have problems. You must be using DDR2 667 or 800 MHz RAM and the two DIMMS must be in slots DIMM1 and DIMM2 ( closest to the processor). No more than that can be installed.

When i switch on a repeating beep comes from the tower and the monitor does not come on . Hope you can help. Sean

Seems like one memory module is faulty/damaged. But BEFORE trashing the module, clean the slots and the chips and try them again. In some Compaqs the processor fan sends the dust to the memory banks producing shorts. You can learn about the beep codes here.

Monitor and keyboard won't turn on

A couple of things here:

1) The flashing light and signal message indicate that the monitor is functioning but is not receiving a signal from the computer.

2) The memory that you added is liklely to be incompatible with the computer itself and is preventing the system from booting. The computer will perform a selftest when powered on. Normally when there is a memory issue, the unit will beep. In some cases, there will be no action.

Remove the added memory and attempt to boot the system. If it starts up OK, then the memory you have added is the problem.

Update this if you require additional assistance.

Montior in Sleep mode

Take out the newly installed memory chip... If your sure its compatable with the motherboard, reseat it correctly into it's slot and fire up the computer. OR try rebooting with just the old memory installed. Monitor blackouts happen when the incorrect Memory is installed OR when the Memory is not seated properly.
stop chasing video and monitor problems...... :)

Compaq Presario 5000 wont boot up

Check the memory, remove and reseat the memory. If that does not work then try and replace the BIOS battery, again if that does not work then it is time for a new motherboard. Do the fans turn on?

Continuous Beep-Beep-Beep.. When I turn on T3304 E Machine

there is a faulty hardware in your PC. here the beep error code this might help to locate the faulty hardware in your pc, and which help you to isolate the problem.

1 Short beep - System is operating normally.
1 Long beep - Memory refresh circuitry has failed which indicates a problem with the motherboard. Try
reseating the memory DIMM or SIMM modules. Make sure if you have added memory that it is rated at the correct speed for the system.
1 Long 2 Short beeps - The video adapter has failed, or the video memory is having a read/write
failure. Try reseating the video card. If the video card is a PCI video card, try moving it to another slot.
1 Long 3 Short beeps - The system does not detect a monitor. Verify that the monitor cable is properly attached to the video card or the onboard video and to the monitor (if the monitor has a detachable cable). If possible, try another monitor on the system to verify that the video adapter is operating properly.
2 or 3 beeps - There is a problem with the system’s memory. Reseat the memory DIMM or SIMM modules.
4 beeps - This indicates a non-functional timer. This indicates a problem with the motherboard.
5 beeps - This indicates a CPU (Central Processing Unit or processor) failure. Try reseating the processor.
6 beeps - This indicates a keyboard controller failure. Try reseating the keyboard connector.
7 beeps - Another indication of a processor problem. Reseat the processor.
8 beeps - This indicates a video memory read/write failure. Reseat the video card (if any) and memory DIMM or SIMM modules.
9 or 10 beeps - This indicates a ROM (Read-Only Memory) checksum error or shutdown register failure. This indicates a defective BIOS chip(s). Reseat the BIOS chips.
11 beeps - Indicates an error in the cache memory. If the system has a Pentium class processor, reseat the processor. If the system has a cache memory module, try reseating it. These beep codes will vary depending on the system

hope this would help.
