It’s possible but can be other components.

How was the RAM checked? Swap tested with known good RAM?

Graphics on-board or separate card? If the latter try a new card.

If the motherboard is a few years old check for raised/leaking caps as in this article.

Reset/clear CMOS – remove battery/check jumper.

Remove any peripheral cards and all connections to the motherboard including hard drive/USB/keyboard then try boot.

Reseat the CPU – apply new thermal paste.

Has the PSU been tested?

Try in this order – easy fixes first.

Good luck.

When I power on my computer, I don’t see anything on the screen; even my computer doesn’t load the BIOS setup. But there is a flash on the screen as a flash occurs before the display appears. I removed / replaced RAM and checked it, but it is not working. The lights of the CPU are coming on when I power it on, fans are working but there is no display.

Is this problem related to the motherboard or the graphics display card or anything else?
