NEED HELP, BOOT MENU FREEZ

[Klemen]

Hello guys How are u ? Bc I'm bad ... =P 

Ok, Let's clear sth first I have wireless keyboard and tried even with wired one 

BIOS is working well without any freeze but right after I Enter in Boot menu, computer freezes and so anything related to "Boot" Freezes. Even if I set in BIOS, Boot priority for like CD/DVD and i put CD/DVD in DVD player it will show to boot from it(u know when it says click anything to boot from CD/DVD) but all what it will happen is . . . . and then it will just throw me in Windows 10. (PS even if i click anything on keyboard won't do anything since I said, anything related to boot freezes or actually do nothing.

Computer is around 5-7 years old 

 

Components ;

Disk - Checked I even swap  it with another one and same story

RAMS - I have 3GB of it but I don't see anything related with freezing,to me it showing that all 3 rams works well and that they are in use.

Power Supply - I'm pretty sure that power supply supplied enough of power to other components.

MOBO - Didn't check it bc i real can't afford any new one bc it would be kinda waste of money (saving $/€ for next mid year new computer)

though I did remove CMOS and get opportunity to play with jumpers but still didn't work 

-- personal thoughts : 

Do u think that CMOS battery is too weak ?

Some of u will say that RAM is faulty, but it can be ? 

and The last MOBO,it can be possible freezing bc old mobo ? 

 

 

But I wanna heared first all of your thoughts. 

 

Thx to anyone who will take time and reply ^^
