The beeps are post during post the very first work is done by the ram,all the memory in the ram is first transferred to the hard disk,and remains active untill turned off.
make sure that your RAM is securely seated
try replacing all the leads that attach to your hard drive including electrical extensions + IDE,SATA the ones that attach from your
((motherboard to hard drive))
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty or just replace them they are probably old and faulty ?
hope this helps

I am currently on my laptop because when I turn on my desktop, the monitor (ViewSonic VX2235wm) powers on with a message that says No Signal Digital and then turns off. Any suggestions?


hi; your monitor has no problem, its your cpu. Try to hook your monitor to your laptop,and change the display setting to your LCD monitor. If LCD has displaying no signal mean signal coming form the Video card of your CPU try to visualize if you hearing some beeps into from CPU, some motherboard has beep codes if there's an error or failure to your CPU, 1 beep means its good system test. if you don't hear any beeps, try to check first your Video Card marmeto12_21.jpg if you have Spare try to replace it, try to reset all the connectors even Memory card to its slot. reset means pull the connectors and place it back again, also check the power supply of cpu if still functioning good.but you can test it by multi volt meter. if nothing happens check your motherboard most common failure is bloating capacitor, and overheating chipset. thanks....................hope this helps...................

Pressing power switch, computer green light below power switch does not come on; fans run; dvd player drive blinks; no boot up. monitor says no signal.


Does the computer Beep at all. If it does, and it beeps differently now than it did previously then that is a POST code and indicates a serious problem. If it Beeps like it used to but there's no video then you should still hear the hard disk clicking - that would be a Video card problem (or perhaps the monitor). If it doesn't Beep at all and it does not make a clicking noise then your BIOS, or Motherboard may be damaged.... perhaps by a failed, or faileing power supply (?)

Signal has gone


If the monitor comes on and displays a message like "no input signal" or something similar, it's working properly but there is nothing coming from the computer. People often think that the computer is working and the monitor is at fault, when in fact the computer isn't starting up.

When you turn on the computer, do you hear the normal sounds of the power supply fan running and the hard drive spinning? Most computers will give a beep when they turn on and the motherboard finishes some startup checks. Do you hear that? Do you ever hear the normal startup sounds that mean Windows is actually running?

If you are convinced the computer is starting and booting into Windows, I would suggest you borrow a known good monitor to use as a test. If it works, that obviously means yours is bad. In most cases there's nothing you can do to repair a monitor yourself beyond checking for loose connections, bent pins in the signal cable plug, or a damaged cable.

If a known good monitor still has no image, the computer is at fault. Either the video card or integrated video isn't working, or the computer isn't actually starting up. In any case, that's where you would need to start looking for the cause.

Hope this helps you along the way to solving the problem. Thanks fo using Fixya!

My monitor is not responding to anything. what can i do aside from rebooting?


do you see the light blinking in the monitor? I mean the POWER led light up? If so, then the monitor is ok and is working good. It is your CPU which has a problem and not sending digital signal for the monitor to display.
Try to turn off your computer. After 3 minutes turn it back on. then notice if you will hear a short beep from the CPU. That signals a successful video initialization. If you went through that process, then your computer will get back to life.
However, if you dont hear a short beep from the CPU, then definitely your CPU is frozen therefore there is nothing to display to the monitor.
You need to open the CPU case, pull out memory modules then plug them back in. Then try booting.
If not successful, try to open case and pull out the processor. Put it back in after 30 seconds. Try booting again.
Do ALL THESE while your PC is UNPLUGGED.
Good luck.

Check the data cable is properly fixed. Can you hear the beep sound while booting. Check the ram inside the cpu.

Lcd monitor won't turn on


Hi,

the fact that there is no picture it doesn't mean that the lcd monitor wouldn't turn on or would be faulty.

It means that the monitor is not getting picture from the computer, the cord could be loose or the computer has a problem and its unable to start up or send signal.

you can try the monitor on another computer that works, to find out if the display works fine.

if the display works fine then the problem is the computer not turning on or starting up, if there is a fault or error you should hear beeps, the lack of beeps may also be a sign of a fault or a error.

What you can do is, unplug the computer for 10 minutes and try turning it on again, reconnect the display cable and try again.

Do you have a screwdriver and is the computer covered with warranty or not? if the computer is on warranty better not to get inside, just contact your dealer and get it serviced.

Gateway FPD1760TFT LCD monitor


Problem
1. turn on computer
2. monitor receives signal, it looks like its working
3. it goes through some steps and then the monitor says "no signal" and kind of stays in limbo with fans running, etc.

Solution
One possibility is that computer is looking for drivers for you video card. It could be hung up looking in the wrong places. Remove all peripheral hard drives and memory sticks. Try again.
