Windows 10: blank screen on boot

i am booting my windows 10 machine with a vga connection to an acer monitor. The computer boots ok as i can hear the windows chime but i cant see anything on the monitor it just goes blank but it is not black it is blue/purple and It is responding to the computer signal. It doesnt say no signal unless i remove the cable. It happened about 4 months ago and seemed to go away when i tightened the cables but the cables are tight now and it is happening again. Is this a problem with the monitor, cable or graphics card? Thanks ...

blank screen at boot up 4850 could it be voltages?

Hello everyone *Smile
I've been getting a blank screen at cold boot up the first time i turn my pc on until it gets to desktop also if i leave it off for a couple of hours or leave it idle at desktop for more than a couple of hours it goes blank again,with all these i get a flashing green power light on my monitor. I was looking at the voltages in RBE in the clock setting and see at boot [clock info 00] the voltage is blank, that includes brets bios's and the default bios as well, as well as being blank in 03 06 09. Ive looked at bios's for the 3800 series and they all had voltages of 1.3 in the boot clock.

Could this be why i get a blank screen on a cold boot or after a couple of hours of inactivity,would it be safe to put a voltage value of 1.084 or something similar in the boot clock info 00?? Would if cure my blank screen problem?
