reported the PC powers up but nothing appears on screen. , and rightly pointed at video and memory as likely areas — below are additional, concrete checks that were not yet covered and that help narrow the fault quickly.

Start at the display: confirm the monitor actually has power (LED state) and that its front-panel input selector/OSD is set to the same connector the PC is using. Swap the video cable type or try a different cable/adapter (pins can be bent on VGA/DVI). If the screen is totally black, shine a bright flashlight at an angle across the panel — a faint BIOS/POST image means the backlight/inverter has failed even though the panel is showing content.

Next, verify the PC is completing POST. Connect a case speaker or watch motherboard POST LEDs/debug codes. Listen for beep sequences and compare with the motherboard manual. Watch front-panel LEDs, CPU/GPU fans and HDD activity; toggle keyboard LEDs (NumLock) during boot to prove the OS or firmware is responding. If the machine shows no POST activity, proceed with a minimal-boot: power off, unplug, remove nonessential cards and USB devices, leave CPU, PSU, one RAM stick and video hardware, then power on.

Power and hardware health: check that any video card auxiliary power plugs are seated, inspect the motherboard for bulging caps or burn smells, and consider a PSU test or swap with a known-good unit. Clearing CMOS (remove coin cell for a minute) can recover bad firmware settings. Use ESD precautions when reseating parts. If these steps still give no picture, the likely culprits are the display circuitry, PSU, the motherboard, or the graphics board — a parts-swap at a shop is the fastest isolation method.

are you using a on-board or a installed card?? if your using a installed card try to use the on-board and vise versa..
if you tried it then may be your on-board or graphic card broke down or your ram might be damaged that's why you have no display..
