Hello,
my computer beeps once and the fans are running, but no signal on the monitor.The monitor only flash "analog'' and ''digital'' . Then the flash slows down and stops.
the problem is not on the graphics card and monitor as I tried them on other computer. I also tried resetting BIOS settings but the problem still exist

Before having completely no display, it keeps flashing for about 2 minutes everytime I turn on the monitor.
Please help

Before this happened did you make any hardware changes, or do anything to the system? Is this a new build? As suggested above, please post your system specs, Motherboard, GPU, Memory, CPU, PSU, or model number of system if it is a manufacture system etc...

One short beep is usually normal. If it is a long beep, it usually means hardware failure as far as CPU, motherboard etc...

If you are able to see the "Analog" and "Digital" messages appear on the screen, the problem is likely not with the monitor but the signal it is receiving. This leads me to either a cable going bad, the output of the card failing, or the motherboards graphics slot failing. When you tested on the second system, did you use the same cabling as the troubled system?

Unplug power while touching hardware. Try removing the ram cards and place back in the same slots again, try boot.failing this also do this with graphics card (a screw or 2 + a clip on the pcie slot needs pressing to remove that)pull out of the slot a little then back in and try this.
if you find this helps clean the contacts later with Isopropyl Alcohol they can corrode over time and have connection problems, greasy fingers touched on them is a good reason they fail too
seen many cards whether video/ram fail to boot at all but after the copper connections were cleaned they fire right up

removed the ram cards and place back in the same slots but it doesn't work, red light flashes once besides the ram cards after switching on. Nothing displayed on the screen now.

Anyway thanks for the suggestions.

Try one stick at a time. Place one stick in the first slot, and boot up. If you still don't get a post screen, replace that stick with the second stick, and boot up. Post back results

Not working. actually the first time removing and putting back ram cards shows the post screen but the keyboard doesn't work. Then I tried that again but it doesn't show the post screen anymore.

if it booted once on post only with graphics after touching ram then we have progress, least might say ram problem area
after ram install and the led came on next to ram did you do the memok buton feature like in this video https://www.youtube.com/watch?v=9azllBzU5PU after that try.....
can you try removing video card altogether as this will switch the motherboard to use the graphics plugs built in to the board , plug the monitor to either graphics port on the board itself and boot that?

removing the graphics card leads me to the post screen which is flashing. Is the problem on the motherboard graphics port?
no difference after pressing memok.

hold it down for more than 3 seconds? The onboard graphics shows but picture flashes on/off on screen?
If both graphics have trouble on the pc, this could indicate a monitor/cable/power issue maybe try another power outlet for monitor . Try monitor from other machine? power point good? power board loose/damaged plug?
