;) Hi there
I am new to this site and have NEVER used one like this before.

I have a problem though and would really like any suggestions anyone might have to offer.

i have a computer that is about 1 and a half years old
the monitor now comes up saying "NO SIGNAL"
I dont have any idea as to what might be causing this problem, but the first thing that comes to mind is maybe my main board is gone????

I hoppe I am writing this correctly. I believe m,y main board is a VISION 915GAVL PRESCOTT MA.

aNY SUGGESTIONS WOULD BE SUPER APPRECIATED.
THANKS

Built from the suggestions already offered by , and , here is a short, practical diagnostic sequence to follow before assuming the motherboard is dead.

Start with the display and cable

  • Confirm the monitor is powered and its input/source setting matches the cable type.
  • Swap the video cable with a known-good one and inspect connector pins for damage or bent pins.
  • Verify the monitor shows an image when connected to a different PC (or connect this PC to another monitor/TV).

Isolate the video subsystem

  • If a discrete card is installed, power down, unplug mains, ground yourself, then remove and reseat the card (and any PCIe power leads). If the board has onboard video, try the motherboard video output instead of the card.
  • Clear CMOS (battery removal or jumper) to reset video selection if the system might be configured for a different adapter.

Listen and simplify

  • Note power LEDs, fans and any POST beeps (as asked). Attach a system speaker if none is present and consult the motherboard manual for beep meanings.
  • Boot with minimal hardware: one known-good RAM stick in the recommended slot, no drives or extra cards. No POST with minimal hardware narrows the fault to PSU/CPU/mobo/RAM.

Power and physical checks

  • Fans spinning does not guarantee proper voltages. If available, test with a known-good PSU or use a PSU tester/multimeter (take appropriate safety precautions).
  • Inspect the motherboard for bulging/leaking capacitors, burn marks or obvious damage.

If all of the above fails, the next logical replacements are GPU or PSU for isolated fault checking; a motherboard fault is likely only after the other items are ruled out. Disconnect mains before opening the case and avoid static damage when handling parts.

Agree, that the first thing to check - your video cable

yeah it could most likely be the cable or your video card

do the power lights come on and does the machine seem to start up ok, apart from the no signal error?
