After boting monitior is getting shut down

When the monitor shuts down, is the activity light on the monitor blinking yellow? or staying yellow constant? Have you tested another monitor? When does the monitor shutdown exactly what is the computer doing at the time the monitor shuts down?

1. Blinking yellow means failing monitor. Not all monitors will exhibit this behavior. For example my Acer Monitor blinks with a blue light when no video input is detected. It doesn't always mean the monitor is bad, but may indicate the video card is failing. Also check and/or replace the video cables

2. Solid yellow means no video input detected Not all monitors will exhibit this behavior. For example my Acer Monitor blinks with a blue light when no video input is detected. It doesn't always mean the monitor is bad, but may indicate the video card is failing. Also check and/or replace the video cables

3. Testing another monitor tells you if the video card is failing. If another monitor works, the problem is your old monitor failing, if a new monitor doesn't work, then the problem is more than likely a failing video card.

4. It is rare but sometimes the Video PCI slots can go bad, while another may work on the same motherboard. This further indicates if it's a motherboard issue, and not the monitor or the video card. Just change the PCI slots the video card is plugged in to and see if it works.

5. Power issues can cause this video issue as well; For example if your PSU is not strong enough to support your video card, it may exhibit no input detected issues past a certain point in the boot process. This is due to lack of power being supplied to the video card. MOST video cards have a warning of sorts if this is a case, but some do not. This issue is more common with higher end gaming video cards and/or lower end power supplies.

The best way to test this is to disconnect ALL devices from the motherboard that require power; For example; CD drives, Hard drives, USB devices that may be plugged in other than keyboards/mice. Only boot the PC with the video card, RAM, and CPU installed. If you get video start attaching 1 device at a time and doing a fresh boot with each device connected. So if the PC boots fine with video on the monitor when the CD Drive is plugged in... it's not the CD Drive causing it. Then hook up the hard drive WITH the CD drive, and see if the PC boots with video then... If it does not, you can infer a power issue might be causing the problem.

Another issue that may effect the video card directly pertaining to power issues are; Try swapping the power cables to the video card with a different power cable. That is to say a power cable coming from the Power Supply that isn't connected to anything or in use by anything else. It is possible a power cable line is bad and/or not working in which case it's a Power Supply issue.

In some cases; This test will be negative on all accounts; At this point, It may be your RAM/CPU causing the issue; Try reseating the ram, that is to say uninstall the ram physically, use a cloth to clean the gold prongs on the ram sticks, and place the ram sticks back into the motherboard; See if it boots up with video then. If it does not; Try removing ram sticks 1 or 2 at a time as required and checking again. This helps determine if it's a specific ram stick causing the problem.

6. If the video STILL is not showing up you will want to check the following.

Check the motherboard for blown capacitors; They will appear in the following forms; Clearly bubbled tops on the capacitors; Exploded tops or yellow crystalized liquid leaking from one or more of the capacitors (like battery acid). This causes a HUGE list of random issues that are symptomatic of power issues. In this case a (Failing Motherboard) Most common on intel and dell motherboards especially on older hardware/PC's.

The CPU is the hardest thing to detect if it's failing, and is rarely the cause, if common sense and care are taken when handling a CPU.

At this point if you still can't figure out what's causing the problem; Replacing the motherboard or monitor is recommended. Monitor if you do not have another monitor to test. Or motherboard if you've exhausted all other troubleshooting steps.

I realize it's a lengthy description, but your description of the problem wasn't exactly specific so I wanted to be thorough and cover all the basis that could cause this problem.

Hope this helps.

The one long-two short beep code is for bad memory, not for a failed video card.
Shut down your computer, remove one stick of ram, reboot the computer, and repeat for each stick of ram, until you find the bad stick.

Computer starts then shuts down no video no beeps\r\nvideo card working power supply working ram working have tried in another computer and monitor.

Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer hard drive

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 a secure connection and are not faulty or just replace them there probably old and 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 electrical extensions or just replace them they are probably old and faulty a computer needs its connections to have an end so any faulty leads will end up with a computer error

hope this will help

My asus m2n32-sli motherboard won't start up; runs for 4 seconds then shuts off. currently hooked up to the mobo: have a 500W power supply; AMD 3300 64 processor; zalman cpu fan; 2 patriot 2GB DDR2...

The only thing i can suggest is remove one of your RAM sticks and see if the machine will boot. I had this problem with mine and it turned out that one of my RAM slots was faulty and would not boot if both RAM slots had RAM in them.

Problem booting into Windows.

This could be a hard drive problem. The hard drive is looking for the boot sector on it, but the boot sector is broken. Computer shuts down and tries again but your hard drive can't find the boot sector so it shuts down tries again etc.

Computer not functioning

Sorry, but looks like the main board is dead (or the main CPU)
The minimum is to have the CPU and RAM installed, so the bios can be accessed.

Fans runs but no post,no beeps.

The best advice I can give you is to remove the motherboard battery (UNPLUG THE PSU BEFORE YOU WORK ON THE MOTHERBOARD) and let the system sit for about an hour. If the CMOS settings are corrupted, removing the battery will erase the corrupted data in the CMOS, which will automatically reset the CMOS to the default settings... Then, plug the battery back into the motherboard, and try to boot the system...

If that doesn't work, you should disconnect EVERYTHING attached to the PSU, and remove ALL of the add-in cards (modem, NIC, soundcard, TV tuner, whatever you have), and install ONLY the CPU, the heatsink/fan (don't forget to PLUG THE CPU FAN IN), ONE stick of RAM... you get the idea. DISCONNECT the HDD, the FDD, the optical drive, and ANYTHING ELSE from the PSU. When you're ready to test the system, you should have ONLY the CPU, the HSF, and one DIMM plugged into the motherboard. Attach the PSU connectors (both the main ATX connector AND the auxiliary 4-pin 12-volt connector) to the motherboard, and try to boot the system. If it works, SHUT DOWN and UNPLUG THE PSU; then install ONE component (the floppy drive, for example), reattach the PSU, and reboot the system. If the system POSTs, shut down, unplug, and add another device. If the system does NOT complete the POST process, the last piece of hardware you installed is probably the culprit.

Take your time with this; be methodical, and make GOOD notes about the steps you've followed, so we can help you work through this problem...

Best of luck to you; keep us "posted" on your progress...
