    I really appreciate your ideas, thanks everyone I will give them all a try, I will let you know if any of them worked, I have a feeling I may have damaged the card I have reinserted it a coulpe of times to make sure I have it in correctly. When I phoned medion they said it was a hardwear fault, would that happen just removing the memory card? They also said the grafic card might have gone down. what do you think?



    Thanks Denyse

Make sure your memory bar is fixed back in place properly, this is the most common and probable cause.

if it is, then you have likely damaged it while taking it off or slotting it back in place

Does it beep? Try removing memory card to see if it beeps when you switch it on with no memory card in. If it does then re-insert memory card. Make sure it is pushed down really hard and side clips are locked in place. Is it in correct socket and correct way round?
If it all looks OK then you may have damaged it with static electricity when you took it out.
In future, whenever you go to remove a PC component always touch the PC chassis first just before touching any component. Same for when you refit - always touch PC chassis first before fitting component. You must discharge static from your body before touching any component.

    On any computer I have known, if you remove the memory card and switch it on it should beep.

    If it does not beep then the CPU is not running.

    Are you sure you did not touch the CPU (processor) at all? Are there any LEDs (lights) on the mainboard that come on when you switch it on?

    Is the CPU fan going round? Does the hard disk LED flash as if it is booting to Windows?

    Check that all PCI cards are fully inserted. Did you accidentally pull out a lead somewhere or move any of the cables connecting to the mainboard?

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.

The motherboard starts up with fans spinning but monitor gets no signal and cant turn off motherboard


If your fans power up but you see no image, then your computer has failed its startup test.
Now you have to find out what the problem is.
Start by opening the case and disconnecting everything but the keyboard, CPU, memory, and video. Now try to start it. If you still have no signal, it might be your video card if the monitor shows a message telling you there is no signal. Memory could also be a problem.
If you get a message telling you there is no boot device, then turn the computer off (push in the switch for about 7 seconds) and connect the hard drive. Now try to boot. If it works, then suspect the CD drive.
If after doing all this you still get no signal no matter what you do, and if the video is part of the motherboard, you're probably looking at a new motherboard.

Hp pavillion 533w wont boot up green light on front comes on but thats it no fans coming on either


Hi ,

If the green light comes on on the front panel then it means the fan is spinning so what u can do is a self test for the monitor.Disconnect the vga cable from the back panel of the computer tower and then check if there is a message displayed on the monitor that should say check video signal or no inoput signal ,if there is no such message displayed then it means the monitor is a fault .If not then reset the memory card and then check .U can also run a test for the motherboard to do this u will have to remove the memory card and then turn the computer on if u hear long beeping noise it means the motherboard is fine .If u dont hear any sound then the mother board needs to be repaired or replaced...

all the best

Monitor is blank


No.. If this is a video adapter issue, you'll still be having a blank screen and not 'check cable' signal. This might be some internal issue with your monitor. You don't you try connecting it to your laptop (if you have) or your friends' comp. And open the CPU cover and see if the graphics card is proper by giving it a through look. Look if the graphics card fan spins. If it doesn't have a fan, switch off the pc. open the cover remove the gcard from its port carefully and then inspect if for any burnout of loose parts.

If your gcard is fine, i suggest you give your monitor for service..
