I have a REALLY annoying computer problem and I need help with it.

The problem is multiple things:

1. When my computer starts up the monitor will 90% of the time, go into standby mode (as if it is not connected to anything). It can happen at the welcome screen OR at the desktop screen when it has been selected and has loaded.

2. When I right click on the desktop and go to Screen Resolution (I have Windows 7 Professional 64-bit) the computer detects more than one monitor, sometimes it's 2, sometimes it's 3 and I think once there were 4. And I only have one monitor, and if I try to change the settings for the monitor somehow, the monitor will go into standby (like the other problem), so these are most likely related somehow.

This starting happening when my brother did a button combination on the keyboard, I don't what it was and he won't tell me, it was possibly Windows Key + L, which is to lock the computer and all that happened was that the monitor went into standby. I told him to fix it but he couldn't, so he just restarted the computer and it's been like this for a couple of weeks, I've been trying to solve the problem but with no luck, that's why I came here.

I replaced my monitor with my brother's and the issue still persisted so the monitor is least most likely the problem.

My Monitor is a Chimei CMV 938D, my brother's is some Samsung one. My GPU is a Gigabyte GTX 260 OC, the exact model is GV-N26OC-896H. My motherboard is a Gigabyte GA-EP45-UD3L.

If you have any ideas to what the problem might be, please share and if you have any questions about my hardware, software or anything, please don't hesitate to ask. Thank You.

faulty gpu?

check other drivers. sounds like a driver problem

put it in another computer, see if it works then.

first try installing other drivers. make sure you run driver sweeper first.

I am currently on my brother's computer because as I was uninstalling the drivers from the control panel on the computer with the problem, the screen went into standby mode. I can't so anything because I can't see if the drivers have finished uninstalling or if it's asking something! What do I do?

Well my brother just uninstalled the Nvidia drivers, now the Windows driver is in it's place and it seems fine so far. I remember reading somewhere that there were really safe Nvidia drivers somewhere in the 185.xx range. Can someone confirm this?

My bro tried installing the newest drivers but the monitor went on standby halfway through the installation, this is most likely because i haven't used driver sweeper or anything. Can someone link me to a tutorial with steps that are easy to understand because last time i tried doing reinstalling, windows update came up and stuffed up everything.

And I really hope this helps......
Try it and let us know how you managed.

yup, select the nvidia drivers in the normal mode from the Control Panel and uninstall.
Reboot .... into safe mode
Run the sweeper....
Let it analyze your system, then from the list of drivers displayed select (ALL) Nvidia drivers including the LAN or other ones if there maybe.
Select clean.
And then reboot

It got the old microsoft drivers......
Go to Windows Update , uninstall the updated driver.... And set the Update option to " Ask me which Updates to Install"
Later on after you have installed latest Nvidia drivers and it ask for the Update to be installed, disable that particular update, and tick the box which says never install this update.

where do i find the driver in windows update?

And Check the Name of the update Last received from Microsoft after you installed or tried to install the Nvidia Drivers, uninstall only that particular update....

Then you must be wrong, when you say that it checks for and downloads an update....
Anyway, go to the Device manager in the Properties of My Computer.
Right click on the Display Adapter , Expand and reinstall Driver, when it says install from windows update or anything else, say no and select install driver from particular location, browse to C:\Nvidia\XXX.xx.xxx for the latest driver where it lies uncompressed on the drive.

yup, exactly

ok
just reinstall it again and then after you reboot, and it automatically selcts the driver.
Follow the steps again, but don't use the sweeper again

Lol ............. Sorry
Are you sure the folder is not there?
Cos you're supposed to be using Sweeper before you installed the new latest drivers from Nvidia.
Maybe it's a hidden folder, so just type the address in the my computer address bar
C:\Nvidia\

and see if the folders inside are there.

have you uninstalled the physx driver too?
If not, then Uninstall that too......

And you'll have to start from scratch after that.
By the way just leave your system on for sometime, check the power saver profile and set all the power option to never shutting down or always on.
See if your monitor shuts off, and then get back.

Nope, it's not since we all ( Nearly ) have the same version, and the date it was installed is today. So it is not the problem.

Does it say Physx driver in the Programs & Features in the Control Panel??

Check this
If you do see the Nvidia Physx like here....
Uninstall it and everything concerning Nvidia, inclusive of Display Control Panel, Physx, Divers all NVIDIA stuff...

Yup, say are you Down Under?

Sweet lil Indian......lol

I don't think so, it'll give you a message like 32bit mode or something of that sort. But you can still give it a try.
You can disable the drivers for you display adapter in the safe mode through the Device manager so I think you might be able to uninstall it (the Driver) for the display adapter from there too...
Try it...

Just right click on that rotating thing and cancel the driver installation

???? Left Click?

Keep it on for sometime and see if it still stays on.
Are you sure your power setting are all on always on??? Check those and get back

Well?? How's it going?

Multiple users should not make a difference , if , you have one administrator and the others are assigned just simple right but disallowed installation or un-installation rights.
Yes, a clean install of Windows should help, but I wouldn't be able to confirm it.
Although it's worth a try since you've been with this problem for the past 36 hours now. A 45 minute installation would really help save time and figure out the problem.
