Hi there

Just finished setting up my new comptuer yesterday, but when I plug in the monitor I only get "No signal" displayed on it, and then it's put on stand-by. Everything else works fine, all the fans are spinning, all the lights are on, the computer is starting up as it should. Just that I can't get it to work with a monitor.

These are the parts I've used when I built it:

* Miditower Svart without PSU
* Chieftec CFT-500A-12S 500W ATX/DualX EPS-12V 120mm Fan 20/24-pin (AMD&P4 OK)
* Asus P5KPL-E iG31 4DDR2-DIMM 3PCI 3PCIe SATA Audio VGA GB-LAN Socket775 ATX
* Intel Core 2 Duo E6850 3.0GHz 4MB FSB1333 Boxed (with cpu-cooler!) Socket 775
* OCZ Titanium 2x1024MB (tot. 2048MB) DDR2 PC2-6400 800MHz EPP-ready
* Seagate Barracuda ST3500630AS 7200.10 500GB 7200rpm 16MB cache SATA2
* BFG GeForce 8800GT OC2 675MHz GPU 512MB DDR3 TV-out HDTV DUAL DVI SLI-ready RETAIL PCI Express
* As monitor I've got a 17" TFT MEDION SXGA LCD MONITOR if that now matters.

I've searched around on google/and different forums all morning (also sat up til 04:00 am yesterday desperately trying to solve it), but still I haven't found any resonable solution for this. I've noticed that alot of people seem to have experienced this problem with "No signal", but I've never seen a concrete answer or so ;/

WHAT'S WRONG?!

- Yes, all the cables are correctly put in (I think atleast)
- And no, I've not messed up any circuit in the mobo or graphiccard when I installed them, been using a "anti-static"-bracelet all the time, or whatever they're called.

Thanks alot for your help!

Short summary for and anyone arriving here later: a new build that powers up but shows the monitor message "No signal" almost always points to the video path (monitor, cable, adapter, or GPU power/seating) or to the machine not completing POST. 's suggestion to swap the monitor or graphics card is a quick, high-value test; the checklist below expands that and provides a recommended order of checks.

  • Verify monitor and cable first: test the monitor and the exact cable on a known-good computer so the display and cable are confirmed working. Check the monitor's input selection (VGA/DVI/HDMI).
  • Confirm the graphics card is fully seated and powered: ensure the card clicks into the PCIe slot and any required PCIe power connector(s) from the PSU are plugged firmly. A missing GPU power lead often yields no video while fans/lights run.
  • If an adapter is used (DVI->VGA, HDMI->DVI, etc.), confirm it’s the correct type: passive adapters require the card’s port to carry analog; some ports are digital-only and will give no picture with a passive adapter.
  • Isolate the video subsystem: if the motherboard has onboard video, remove the discrete card and try the motherboard output. That separates a bad card from other faults.
  • Memory and POST: reseat RAM, try one stick in the recommended slot, and attach a system speaker or watch motherboard LEDs for POST codes. Clearing CMOS (jumper or remove battery briefly) restores defaults that can resolve primary-output confusion.

If those steps fail, try a known-good PSU or GPU, and consider a breadboard test outside the case to rule out shorts from standoffs or misplaced screws. Use ESD precautions and consult the motherboard manual for beep/LED diagnostics before returning parts.

Do you have another monitor or computer you can use to see if its just the monitor? Also do you have another graphics card that you could swap out to see if that is the problem?
