Laptop Does Not Detect GT540M After Format

aspacecake
hey

i just formatted my laptop's hard disk, Acer Aspire 4755G, and missing a ton of drivers, notably my graphics driver for Nvidia GT 540M. I downloaded all 3 of the drivers off the acer website under the Graphics section, but none of them seem to work. The driver update says "The Graphics Driver Could Not Find Compatible Hardware". It appears that my computer does not detect my graphics card. How can i make it do so?

Reading some other forum posts say that i have to go to Device Manager. Under display adapters, i have two "Standard VGA Graphics Adapter"s, one has a yellow triangle one does not. Right clicking both and updating however gives me a message that they are both updated.

My laptop was fine with its stock drivers during purchase, and it detected my nVidia GT540M fine, thus i'm wondering how to get it to recognize it now

Any and all help would be appreciated, thanks

update : nVidia drivers do not solve the problem of unexpected shutdowns. besides, it's a shutdown and the screen suddenly goes black accompanied by the sound of an abrupt shutdown, not an issue of screen freezing or distorting and me having to manually restart - thus i'm sure its not an issue of my graphics driver crashing. any other ideas as to what could be causing this problem, if it's not a graphics driver crash or overheating (really dont feel any heat at the cooling vents, and i've had another overheating laptop before) ?

If the BIOS has it the heat setting could be set too low and cause this to happen. Ive seen cases where some BIOS's have been set to 50C shutdown which is way too low.

Also what are the Power Settings in Windows here? That could just as easily be the problem.

My BIOS does not have heat settings nor sections for PC Health under BIOS. Power Settings. Am i not doing it right?
The system cores are at 50 degree celsius when idle or surfing the net, and 70 degrees celsius when gaming. A quick google search says those are mostly fine. Could it be that i have a last driver or so which i have yet to install?

Some NB's do not have the Shut Down Temps in the BIOS. This was introduced by Intel many years ago to save the CPU in the event of a Overheat. I've seen some M'Boards shut down the system when the CPU hits 60C which is way too low so that was what I was thinking above.

Look in the Acer ePower Management Software for the Shutdown Temp or if that is not installed you'll need to **** out the Air ways of the NB to clean the crud out of it. You can also hit the Power Management of Windows to see if there is something there that shuts the system down but the Acer Software should override it though it just may not work quite right so you'll also have to check Windows as well as the Acer Power Management Software.

I have seen some laptops get glitchy when the lid is opened/closed because of breaks in the wires.

what you should try is look through the start-ups / msconfig and services /admin tools and tasks control pane to shut down unnecessary programs, like google updaters, av updaters, etc...

for all practical purposes, you don't need automatic start-ups loading in memory when windows starts.

you don't need non window services running.

and you don't need any tasks being scheduled to run behind the scenes without your knowledge and permission.

so see if streamlining / tweaking your computer will help dedicate the resources to your game.

if the computer and the game does become stable, then the only thing i would turn on in the start ups is the anti virus "and" maybe the laptop kb and laptop mouse - that is if your laptop needs them loaded automatically.

then monitor the panels i mentioned on a regular basis because applications will sneak in their resource hogging crapware at every chance they get.

if however, the computer seems unstable even after you streamline it, then boot into safe mode and execute a restore point to undo your modifications and go back to square one.

I would suspect thermal stress on the GPU (e.g. are you pushing the game settings as high as they will go?) You said the fans are going, but internally it could be the GPU heatsink is marginal either mechanically or the radiator surface could be gummed.

I just realized that apart from formatting, that same day i added 4gb more of ram to (the 2gb of ram default on purchase) in my system. Could it be faulty ram causing this overheating? I did not think it would be an issue because I saw a marked performance in my gaming and the system registered 6GB total ram. Could it be possible that compatibility issues exist? Or should i open up the back of my laptop casing and try to clean the fan/heatsink?
Just removed the 4GB of extra ram and the computer is running fine now.
If the 2GB and 4GB ram sticks are incompatible together, should i just use the 4GB ram by itself, since it's superior to the 2GB default? or will the faulty 4GB ram hurt my hardware in the long run?

sorry no the fans ARE spinning, but the problem is that I am unable to set the temperature at which the laptop shuts itself down. There is no available feature in the BIOS (System, Information, Security, Boot etc etc but nothing with regards to fan/shutdowns) and the Acer ePower Management v3.0.3010 does not work , crashes upon opening the application in Program files
