No Display from the Graphics Card Either Seating Power and Cable Checks
The cable is in the card this time, and the screen is still black. Do not panic and do not start reinstalling Windows - after a fresh install, the cause is almost always physical. Work this list in order.

Watch the full fix in the video - GPU installed, no display from motherboard, solved step by step
There is an important difference between the motherboard port going dark (normal) and no display from the card itself (a real fault to find). The good news: on a just-installed card, the culprit is nearly always one of four physical things - the card is not fully seated, its power cable is missing, the monitor is on the wrong input, or the cable is bad. This checklist goes through them calmly, cheapest first.
No Display From the Card - Check in This Order (illustrative)
1. Monitor input sourceMatches the cable port
2. CableFully pushed in, try another
3. PCIe power cableConnected - card end AND PSU end
4. Card seatingFully down, latch clicked
The order that finds most faults in minutes - example checklist, not a screenshot

Check 1 - Monitor Input and Cable (2 Minutes)
Confirm the monitor input matches the cable: HDMI cable means the monitor must be set to that HDMI input, not left on auto or DisplayPort.
Reseat the cable at both ends until it clicks or seats firmly.
Swap in a different cable and a different port on the card. Cables fail silently more often than any other part in this story.
If the monitor shows its own menu fine, the monitor itself is alive - the signal is what is missing.

Check 2 - The PCIe Power Cable (the Classic Miss)
Many graphics cards need more power than the slot provides, through 6-pin or 8-pin PCIe power connectors on the card's top or end. If that cable is not plugged in, the card may show nothing at all - or spin fans and still give no picture.
Power off and unplug the PC. Open the case.
Check every power socket on the card is filled with a PCIe cable from the power supply - not a CPU/EPS cable, they look similar but are keyed differently and serve another job.
On modular power supplies, confirm the other end is plugged into the PSU as well.
Do not use loose adapter chains for high-power cards; use the proper cables your PSU came with.

Check 3 - Seating in the Slot
Remove the card completely and look at the slot and the card's gold contacts for dust or a bent bracket.
Push the card back in evenly and firmly until the slot's latch clicks. A card can look straight and still sit one millimetre high at one end - that is enough to lose the display.
Screw the bracket to the case so the card cannot sag or creep out, and check a heavy card is not pulling down at the far end.
Try the card in the top full-size PCIe slot if you used a lower one - the top slot is the one wired for graphics on most boards.
After these checks, if there is still no picture anywhere, test the card in another PC or test the PC with the card removed. Splitting the system in half is the fastest honest diagnosis - the confirmation-test guide in this set explains what each result proves.
Watch the Complete Fix in the Video
The video covers the display side of a GPU install - watch it alongside this checklist if your card itself is giving no picture.
The card's fans spin but there is no display. Is the card dead?
Not necessarily. Fans can spin on slot power alone while the card still refuses to initialise because its PCIe power cable is missing or the card is not fully seated. Work through the power and seating checks before concluding anything - a truly dead card is the last verdict, not the first.
My power supply has no 8-pin PCIe cable. Can I use an adapter?
For low-power cards, a proper adapter is a tolerated stopgap, but chained molex-to-PCIe adapters are a known weak point and a poor idea on hungry cards. Honestly: if the PSU lacks the connectors the card needs, the PSU is undersized for the job and upgrading it is the real fix.
There is a picture in Windows but not in BIOS, or the other way round. Why?
That pattern points at handshake quirks rather than a dead card - often the monitor waking slowly, a specific port behaving differently during boot, or an old monitor with a newer card. Try another port on the card and another cable; if Windows works normally, the system is healthy and this is a display-chain quirk to live with or chase gently.
