Asus m4a785td-m Evo motherboard bios load issue

[Chippa]

Hi, help needed if anyone can spare any knowledge for me.i understand its an old spec now but been reliable enough for me until this.
bootup suddenly doesn't show bios screen/menus.So can't do anything!🥴
I don't know how to upload video of what happens.
So I have screenshot 4 pics of what happens when power button pressed.
1st beep from board sounds normal,
Bios screen should show up.
I always have connected from onboard hdmi port to TV.
Tried VGA lead same issue.
Also tried swap ram,and clean everything.
But with no luck.
System is
Asus m4a785td-m Evo motherboard,
Phenom II X4 965,
8gb ram ddr3.
240gb SSD.
Any info,advice will help.
Nothing seems to make any difference.
Thanks in advance.

Sorry for double posting,
Anyone?
Motherboard beeps once as normal as if all is ok.then ends 2 beeps.
Tried just 1 ram,same.
VGA lead is same display.
Always worked with TV no problems.
Tried monitor same.
Would or could CPU failure cause this?.
I don't have money for buying a new one,
If any chance to fix this for now,that would do for me.

are the beeps listed in the manual?
if not you could try the asus forums.
other things to try:
replace the battery and reset the cmos settings,
flash the bios - it's in a socket and the board may be able to emergency-flash it from a usb stick too.
these may help
