Hi,
Causes for no display are :
1. SMPS : Most likely, replace
2. RAM : Most likely, replace
3. Motherboard : likely if it is old
4. Processor : unlikely if it is Intel
5. Graphics Card : Try on board graphics
Thanks

Moderately Experience Comp Repair Girl Needs Some Help.


Well this usually happens! Its weird but I have no more theory, with a new Power Supply will not work, believe or not sometimes old computers [or in this case motherboard] will not even boot the BIOS with a different power supply than the one that the motherboard has always used, sounds weird but if you try it, you will see that will boot like if nothing happened before... give it a try and tell me how it goes... Best regards and LUCK!!! Luis

When I tern on my comp it is 3 beep what a problem


The Problem With RAM, If 3 short beeps( AMI bios). Video Problem Display Problem if One long beep and 2 Short beets( Award bios)

Remove the Power Connector from PC, and Open the cabinet and Locate the RAM, Remove it and put it back to same or diffent socket, or Try with New RAM.

if still no Use then it is the Display Problem, If display adapter is Onboard then motherboard needs Repair(Chip Level). try with new Graphics card. If you have any Graphics Card earliar then Try with New one. best of luck

Keeps telling me no signal


The motherboard is not telling you there is no signal, the monitor is..
In this order:

  1. Test the connection from graphics card to monitor, try a different monitor to eliminate this from the issues.
  2. If other monitor works, the old one is causing the problems
  3. If new monitor does not work:
  • Check the graphics card is seated properly, if possible, test with another graphics card, if this works, the issue is with the graphics card
  • If this does not work, check the fan on the cpu, is it spinning? If not, make sure the fan is connected to the motherboard
  • If the fan is spinning, remove all the ram, reboot, you should get a series of beeps, make note of these and repost them (computer will not boot)
  • If you get NO beeps with ram removed, the CPU or motherboard are possibly dead, if possible, replace CPU with known working one and retest with and without ram in, make sure you have thermal grease on the CPU>heatsink. Replace the Ram (or one module)
  • If you get a single beep and the motherboard powers the monitor, the CPU was your issue
  • If you get no beeps, confirmed death of motherboard.
Possible other solutions: Remove CMOS battery, leave for 1 minute and then replace, see if it boots
Check the power switch from the computer front panel is not sticking

DEAR SIR IAM USING COMPAQ PRESARIO SG3053IL MODEL PC WITH FOXCONN 945GZ7MC MOTHERBOARD.PAST IT IS WORKING FINE. BUT RECENTLY WHEN I SWICHETED IT ON, I OBSERVED NO DISPLAY IN MONITOR. COMING TO MY...


I don't think we should directly blame it to the Power Supply, but I can't make it very thorough since you didn't mention whether the system can boot up or not even without display or not. Can you hear beeps or fans' sound when you press the Power button on the computer? Have you tried the monitor on another computer? or have you tried another monitor on your computer? or have you check the video cable? Have you checked the Ram? Have you checked the power supply unit (smps)? Have you checked the Power cables? and many more. If you haven't done all these, do one by one and replace the necessary components respectively and keep trying, if nothing's worthy, then it must be the video card on the motherboard which I would recommend installing a new video card (add-on graphics card). It's also possible that there's problem with the Motherboard bios.

In most cases, the Ram is the cause, once you replaced or checked Ram, you'll be able to find out what exactly is the root of the problem.

These are the basic steps of troubleshooting a display problem.

If you need further help, let me know.

Good luck.

Thanks for using FixYa.

Motherboard power is on but cannot display screen, the monitor is black or no screen.


your problem could be almost any of your hardware components
the best way to detirmine wich one/how to fix it is with a process of illimination. You should do this by switching your hardware components with known good ones.
being a display problem the order i would test with is this.
  1. disconect everything but the screen
  2. swap screen for a known good one
  3. disconect graphics card and try the onboard (if no onboard try another gc)
  4. test psu (power supply unit) this can be done with either a psu tester, multimitre or try with another psu
  5. try removing all your RAM, when you boot if your system beeps a couple of times you know that your motherboardand cpu are good. if it doesnt beep it is probably your motherboard or cpu.

DO ANYBODY KNOWS WAT TO DO IF DISPLAY NOT APPEARS


The 280W may not be supportive enough for the computer requirements and is not diverting its power correctly to power the VGA part of the motherboard.

If the PC does not to any beep then usually is a problem with the motherboard.

If the PC does a certain number of beeps on startup, then tell me how many beeps to troubleshoot the problem.

If the computer does single beep on startup as usual, then may be the monitor, monitor cable or graphic adapter.

Simple thing that you can do it yourself is disconnecting computer power cable from power outlet for 15 -12 mins. ac connect it back, this will solve troubles caused by electrostatic charges.
Also check video cable connections to monitor.
If you have another computer also test the monitor on other computer.
If the main unit is not booting (CD drives and internal fans often start up even if the Motherboard is blown). Then yo need to open the pc and test component inside.
If you have practice in fixing hardware you can start removing RAM modules and testing them, then buy a tester board for the MB and do a diagnostic test on motherboard.
Other options are taking PC to service or getting a new PC.
If the PC is still under guarantee, then contact Acer to validate your guarantee and get the machine to an authorised service centre.

Is motherboard dead?


Either motherboard, ram module or if no power at all sounds more like a power supply. If the computer has on board video you will need the ram to get any video. But with it removed the board should still beep if the case speaker is connected to the board. Have seen a lot of these less expensive motherboards fail. If there is no power up at all or lights coming on on the case I would think it is a power supply problem. Happens all the time and quite easy to repair. Just put on a new power supply.
