I just built this PC and everything seems to be running fine, well as far as i can tell without being able to see anything on a monitor. The fan on the graphics card is spinning but when I plug the monitor I cannot get a signal. I cannot plug my monitor into the motherboard.

specs:

AMD FX-4100 Zambezi 3.6GHz (3.8GHz Turbo) Socket AM3+ 95W Quad-Core Desktop Processor
ASRock 970 EXTREME3 AM3+ AMD 970 SATA 6Gb/s USB 3.0 ATX AMD motherboard
PowerColor AX6770 1GBD5-H Radeon HD 6770 1GB 128-bit GDDR5 PCI Express 2.1 x16 HDCP video card
CORSAIR Builder Series CX500 V2 500W ATX12V v2.3 80 PLUS Certified Active PFC Power Supply
G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Desktop Memory
1tb hard drive
windows 7 OS

thank you.

Good outcome — thanks to for the nudge and to for confirming the result. For anyone who lands here later with a new build and a blank screen, that symptom is usually down to a simple hardware or connection issue rather than a mysterious incompatibility. The checklist below is concise and ordered so you can isolate the cause quickly.

  • Verify the monitor and cable first (switch the monitor input, try a different cable or a known-good monitor).
  • Confirm any auxiliary power cables that attach to the graphics card are the correct plugs and are fully seated and latched.
  • Reseat the video card firmly in the PCIe slot and make sure the retention clip is engaged. Try another PCIe x16 slot if available.
  • Do a minimal POST: board, CPU, one stick of RAM, and GPU (or onboard video if the board has it). Remove drives and extras.
  • Swap RAM sticks and slots to rule out memory preventing POST.
  • Listen/watch for motherboard POST beeps or debug LEDs and consult the board manual for their meanings.
  • Reset/clear CMOS if settings might be interfering with device initialization.
  • If possible, test the graphics card and PSU in a known-good system, or test the system with a known-good GPU.
  • After you get a picture, install/update graphics drivers and motherboard BIOS for best stability.

Notes: fans can spin while the card still won’t initialize — fan motion alone isn’t proof the GPU is powered correctly. Avoid using questionable adapters or splitting one rail excessively. Handle parts on a non-conductive surface and watch for loose case standoffs or front-panel wiring that can prevent a proper POST. If none of the steps produce video, gather error indicators (beeps, LED codes) and consider vendor support or RMA.

VGA connector. I'm not 100% sure they are compatible. I came up with the build myself and had it checked online and by two friends and all three said it looked fine. I do not know how to check to be 100% sure they are compatible.

i check the board and card makers and it should work , the board is pci-e 2.0 and the card is pci-e 2.1 but it should be backward compatible and work with the board ,any chance there could be a problem with your monitor, you did plug the One 6-Pin PCI Express Power connector into the video card ,right

I did not have the 6-pin PCI express power connector plugged into the video card. THANK YOU!
