The monitor receives
a signal from the CPU every time it starts up. This signal will be
translated as an output to the screen, along the way if there's an
issue with booting up (for example) no signal is being sent, thus
it will normally remain blank or with the message (no signal).
However, if there's a
signal sent, but there's a fault with the signal. (white and cyan).
Most of the time. The channels sending the signal (the cable) is
the main culprit.
On the 2nd boot (your
forced reboot), when it boots up, the CPU will resend this signal
again.
If it's a failing PSU
issue, there would be a pop up from the Nvdia with this mesage -
"low power". (Correct me if I'm wrong about this point)
I don't think it's a
driver or graphics card issue at all. You can try though. (The
latest release on Nvdia's website should be 25/10).
I do not know if by
definition how you switch on and off your monitor. (I presume it's
via the on /off button)try switching off the monitor's power
instead (socket) then switch it on - instead of rebooting if
it works, that means it's the monitor and it's most likely the
cable like seykai and troublemaker has said.
oh, I did swtich off the monitor power socket, waited like 5-8 sec
then switch back on... but it's still either white or cyan or blue
(like wat troublemaker said).
However, when my fren tried the same method (off and on monitor
socket power), it worked, but not when I try, wierd though...
Actually I still can go in windows in the
first bootup but the problem will appear after like 15-20
mins...
Maybe I'll go simlim and get another cable for another
monitor... I do have 2 other monitor (which are larger
screen) but from wat my fren told me, the series tends to heat
up fast but then again, I'm not using it for long period of time
due to work...
