Windows 7: No Display when booting 9/10 times

Win 7 Pro x64/Win 10 Pro x64 dual boot

If it isn't booting 9 times out of 10 right now, I would put off the upgrade to Win 10 until you can find out what the problem is. It's starting to sound like you have a flaky power supply or motherboard.

win7 64

hey, did not read ur msg, i think i missed it because it went to page 2 and i thought noone had answered.

anyways, i didupdate to win10 a few days ago and everything went fine. still had the no signal problem when booting though.

couple days passed and today it got way worse: now, after trying to boot for a few times and only getting the "no signal", i now get a BSOD that says either "No bootable device found" or something along those lines, or it says something about automatic repair, PC did not start correctly, restarting might fix the problem. (my windows is not in english so thats a basic translation). after i click restart, i am basically back to square one where it will either show no signal, or one of the 2 BSODs.

would really appreciate any help. how do i figure out which of the components needs to be replaced?

win7 64

if it was the RAM that is causing the issue, would/could it stop the HDD LED from lighting up at all?

i guess the key to this problem is the fact that whenever i get NO signal and only fans move, the red harddrive LED is not lighting up at all, ever.
i would keep trying to power on / off and eventually the red LED would light up and i would get a signal on my monitor shortly after. and the PC would run for hours w/o any issue. i am really frustrated and do not understand what could be the reason for that.

edit: i noiced that in those cases that i would get no signal on my monitor and the red LED would not light up: when i would press/hold the reset button, chances are the red LED would light and signal would come.

since today in those cases i do no longer get into windows but would get the afforementioned BSOD

again more info: i have 2 RAM sticks, they both worked for a very long time. right now, if i use them both (installed into the right dual channel slows), i get 4 fast POST beeps. they work individually though, more or less (no post, often no signal, eventually a boot with signal).

Non responsive black screen at random times when booting up
I have been having some issues (a non-responsive black screen) when I start up my machine for the past few months. Initially it was only when Windows 7 started up, but of late it even hangs when I go into the BIOS. I initially thought it may have been an issue with Windows itself but now I'm not...

Windows7 (64bit) booting fails every 5 or 6 times.
I almost think this thread's title says it all: it seems that after around a handful of successful boots, that after I enter my password successfully, the system transitions to the next window where it proceeds to hang indefinitely. At that point, I power down, wait a minute and then power up....
