Monitors stop working - have to reboot to get them on


Thread Starter
Jan 22, 2007
I recently upgraded to window 10 pro from windows 7 pro. I seemed to be OK until just recently when my monitors went dark. I can reboot and get them to come on, but if I leave the system on overnight - in the morning they are off again.

I had a system crash on my windows 7 computer brought on by a failed power supply fan (I think). I replaced the power supply and thought I was OK. until now.

If it seems to be my graphics card - which is Radeon 6450 - and rather old - I have no problems replacing it, but I'm at a loss.

it seems that I have 2 separate systems running at the same time.

I did go to device manager and update my software this morning, but then it shows no drivers are installed for my graphics card. and that none are required. it shows the update, but then 'no drivers installed or required' is the message.

when I rebooted with the 'new' drivers - I have to reset the screen - they came in too big. I just haven't done that yet. I wanted to ask first and make sure my post went thru.

I'm not a total novice to computers, but haven't done much lately. I'm at a loss. I do run 2 monitors. one DVI - the other HDMI. it only detects one monitor.

twice now my system stopped working and I got these messages.
1: (first time) we're looking for errors and will reboot - system service exception
2: (second time) Page Fault in Non paged area. (it had to reboot again)

For the monitor(s) not turning back on, try disabling hibernation and/or fast startup:

Fast startup uses hibernation so if hibernation is disabled both are disabled.

If it does it again, try restarting video driver with the hot key combo: Win + Ctrl + Shift + B
See if that wakes the monitor(s).

If still no luck, update BIOS and video drivers.


A.6 is last version, it's from 2016 so may already be installed. Check what version you have by going into BIOS (press DEL at power on). Version should be shown at top center, under the date, on the main screen.

Make sure to read the pdf ( and watch the video linked there (
) if you don't know how to update a BIOS. Requires a USB Flash drive (most any size will do, formatted as FAT32).

Radeon HD 6450 drivers:

Get Win 10 64 bit Catalyst Software Suite
