Dell inspiron 530 desktop won't boot, fan is running, no signal on monitor


It sounds like either your monitor or video card inside the computer is bad.

If the monitor is showing the "No Input Signal" message then the video card inside the computer is bad. The monitor is ok otherwise it would not be able to display the No Input Signal message.

When you plug in the power cord is there any lights whatsoever on the laptop, where the plug goes in or on the AC Adapter of the power cord?

When you press the power button do you hear fans running, hard drive spinning, lights on the computer, hear any beeps or lights constantly blinking, hear the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two? If so the computer is trying to boot or may have booted, but the screen is not showing for some reason.

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 you have a Static Charge Buildup. Remove the Power Cord, then Press and Hold the power button for 30 seconds. After 30 seconds plug the power cord back in and hit the power button to see if it boots.



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.

Computer won't boot


OverheatingWhen the CPU overheats then it will shut down (i.e. thermaloverload) and won't boot up again until it has cooled down. If this is theproblem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are cloggedwith dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make surethe vents are clear and dust free. Use a small brush and can of compressed airto do this.

I have an hp pavillion a6500f that soon as it is turned on has a constant alarm and is not sending a signal to the monitor. Screen says no signal and then remains black.


If you mean a constant beeping, open the case and see if the CPU fan is running, check also that the heatsink is firmly attached to the board, this noise usually points to a n overheating CPU, if you get no activity on screen,it is because there is no signal being sent to the monitor. Do not operate the computer until you have checked the fan is working, you need to establish if there is power getting to the fan by testing with a multimeter on the motherboard cpu fan pins. If you are getting power, replace the fan, worthwhile removing and regreasing the CPU and making sure it is firmly in place.

If there still is no signal, replace CPU, but also try a different graphics card (faulty video will give 9 beeps).

After that, check the ram is firmly in place.

I have to run my unit in safe mode or else the cooling fan constantly runs and then shuts itself down. Its only 2 or three yrs. old. Junk or fixable.

Turns on fan runs but no info to the monitor doesnt seem to boot


If the Monitor is displaying no infomation at all, your display signal from the PC to the monitor has failed.
1: Check the cable between the monitor and PC
2: If you are using onboard graphics then that display port is faulty.
3: If you are using a graphics card then remove it and try the onboard graphics.
4: Your monitor maybe faulty aswell so test it on another computer to be safe.

Its more likely to be option 2

Wont boot and no signal to the monitor


Try running it without any ram in, as bad ram could cause that. Also you may have shorted your motherboard. It sounds stupid, but did you remember to put your standoffs on?

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.
