My laptop is Asus u45jc-a1


i3 m370 @ 2.4 ghz processor

4gb ram but i recently upgraded it to 8gb ram

250gb ssd samsung


Last year i bought a monitor that is hp la2405x because it has 1920x1200 resolution which i need because i need it to play online poker. I would connect my laptop to the monitor by vga cable. I noticed that the monitor would keep on going to sleep. Example i would be on the computer for few hours or play poker for few hours, then this message would show up. Then my HP monitor screen gets the no signal and then go to sleep and when im playing, i have to wait like 1 minute or so, then hold the power button on my laptop for a few seconds then it turns off. The i press it immediately and then it would show resuming windows. This was the fastest way for me to get back on the tables when not sitting out longer.


However if i dont wait 1 minute or so and then i just press/hold the power button immediately, then i would shut down my laptop which is horrible because if im playing tables, then i have to wait a few minutes due to having to power up the laptop again.


I then wondered if this was my monitor or it could be my laptop as i read it has something to do with video card? Well what happened was later on, i didn't seem to have this issue anymore then after a while it came back again. This is very annoying when playing on pokerstars due to you going to miss out few minutes if you close the computer while playing because you going to be sitting out etc.


I then later on tried my laptop on another monitor a dell one. Note this monitor is very old, like 8 years at least. Similarly it had the same issue. It would go to sleep just like the HP one which when i bought it was brand new. The thing is you never know when its coming, it might happen once a day, twice a day, or 3 times, sometimes none. Im currently using another monitor and i had this issue yet again. This monitors an Acer. However, it doesn't say go to sleep like the HP one. All it does is have the no signal message. All of these monitors i connect to my asus laptop by the vga cable.

Dear all,

I have found a solution to most of your problems.

Simptons: Black screen after installing Nvidia Graphics Drivers

Solution: If your motherboard has an onboard graphics card, disable the onboard and set it to boot from PCI Express slot 1 (if you have it in slot 1, if not so then set it to boot from whatever slot you have put your graphics card in). Once done so, restart and it should go to the graphics card and boot up as normal.

(These problems mainly occur on the GIGABYTE boards with the UEFI BIOS

Problem: Certain motherboards (mainly intel type boards) fail to disable the onboard graphics when PCI graphics is installed.



Does this require you to open up the computer?
