Hi daniweb

I recently built a new pc with father but as we power it on all the fans work etc but the monitor goes from no cable connected to to no signal then goes to standby. All the power is in properly and the gpu is in the pcie slot properly. We tried it with another monitor and got the same result.

Gtx 560 ti twin frozr ii
corsair 2x4gb 1600 mhz ram
asrock extreme3 870
amd phenom ii x4 955 be
not using stock cooler but that fan still works perfectly by looks of it.
Neo eco 520w power supply

We are quite stuck here, we hace tried differnet power combinations etc but no luck. The menu on monitor wont work wither while the computer just loads up. Windows is not installed yet.

Following up on s thread and building on s and s suggestions, here is a compact, practical isolation workflow to find why a system powers but never shows video.

  • Get POST feedback first. Fit a small chassis/system speaker (if the case has none) and note any beep pattern. If the board has POST LEDs or a two-digit POST code, write that down and consult the manual.
  • Breadboard the system outside the case: CPU, one known-good RAM stick (try each slot), PSU, and speaker. Remove all drives, extras, USB devices and add-in cards. Boot with that minimal set.
  • Verify all power connectors are fully seated (main ATX and CPU EPS, plus any PCIe power to the video card). Use different PCIe slots if available.
  • Clear CMOS with the jumper or by removing the battery for a minute, then retry.
  • Swap components to isolate: test the video card in another working PC, or try a different card in this system. Also try a known-good PSU or use a PSU tester/multimeter for rail checks (paperclip/startup checks are only for quick testing and should be used with caution).
  • Inspect the board and CPU area for bent pins, blown caps, or scorch marks. Document with photos before removing parts.

If minimal-boot still produces no POST or codes, the fault is usually motherboard, CPU seating/pins, or PSU — pursue RMA for failing parts after confirming with cross-test results. Take ESD precautions and keep notes of each step.

Usually these systems have some sort of boot error indications in the audio beeps. Do you hear anything out of the system speaker (not external ones, but one built into the system enclosure)?

If you have another graphics card, try swapping it out, it may just be a bad card.
