Laptop Does Not Detect GT540M After Format

By 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

Well it's quite simple really

by OH Smeg In reply to Laptop Does Not Detect GT ...

You didn't use the Acer supplied Install Disc/Recovery partition and did not get the Install Method along with the Supplied Drivers. I would assume that you used a Windows Install Disc which doesn't have the Specific Drivers for your Hardware so you have to install it after you install Windows.

Not sure what really happened with the Video Driver but if you go into the Device Manager and Right Click on the 2 listed and go to Proprieties and see what they say that they are should be a starting point.

Also depending on how you installed the OS here you may have forced it over something and it's messed up the various Drivers.

If you where using a Vanilla Windows Install you should first install Windows and then the Audio Driver and then the Video Driver if they where not loaded when you loaded Windows.

Here I would start again with a New Clean Install after formating the HDD and then if you didn't keep the 2 NVidia Drivers download them again and install one at a time. It's also possible that the smaller driver of 24 MEG is the wrong one and I would suggest applying the bigger of the 2 NVidia Drivers first. If that doesn't work reinstall the OS again and this time use the smaller Video Driver.

Of course if you didn't install Windows 7 Acer doesn't supply any drivers for a different OS so you'll have to hunt the necessary drivers for whatever version of Windows it is you are installing.

Hey thanks for the reply! I have since solved this problem (unsuitable drivers, you were right!) , and i have come up with yet another problem. Since the formatting, my computer shuts down every once in a while (an hour or two) and it's abrupt, as in the screen suddenly goes black and all lights turned off. I thought it was my charger connecting to the laptop port issue, but even after leaving the battery in the laptop still shuts itself off every hour or two randomly, thus i believe it is not a power issue.
what steps should i carry out to take care of this problem?

could be bad hardware

by databaseben In reply to Laptop Does Not Detect GT ...

If you were experiencing problems before hand and the re-installation couldn't fix the issue, then you likely have a hardware related problem.

unfortunately, faulty hardware cannot be fixed via software and you will have to send it in for repairs.

Well you didn't say why you reformatted the hard drive. If it's bad that might be a source of instability. (e.g. suspend mode)

I've seen machines freeze (not black screen) if there are problems with the gfx driver. I'm assuming you went to the Nvidia site to get the latest driver, if so did you reapply DirectX afterwards?

Good luck!

Sounds like overheating issue.

by Craigceg In reply to Laptop Does Not Detect GT ...

It could be an overheating issue which is common in laptops that are several years old. You need to make sure the built up dirt, dust, pet hair etc is cleaned out of the CPU fan and exhaust vents. It is better performed by partially disassembling to get to the actual CPU fan than it is to just blowing through the vents. Blowing through the vents usually does not break up the big chunk of accumulated junk. Just a thought...

As for the unexpected shut downs

by OH Smeg In reply to Laptop Does Not Detect GT ...

Does this happen while you are using it or when it's idle?

If it's while you are using it it's most likely a heat related issue which may be fixable by changing the temp in the BIOS that the system shuts down. If you have that option in BIOS change it to 90C for the shut down.

If it happens when it's idle it sounds as if you have the system set to Hibernate and quite often this causes problems so it's a good idea to turn off Hibernation in the Power Options. .

As stated above heat and NB's is a big issue and with a few years use the internal cooling vents get clogged with Dust and other Crud. You need to **** this out with Canned Air or something similar but don't use a Vacuum Cleaner as they generate Static in the Air Stream which is deadly to Electronics. If you use compressed air you also need to stop the fans from spinning because they also generate electricity when they spin and this isn't good for the electronics either.

I personally always supply a Cool Pad with every NB that I sell to stop then getting clogged with Crud or having things sucked up against the bottom of them and blocking the air intake and causing overheating. I use Antec Cool Pads like the one here

remember to remove the space from between antec and the .com for a link.

But there are cheaper alternatives available on places like E Bay.

As a side note

by Slayer_ In reply to Laptop Does Not Detect GT ...

Ditch the acer drivers. Go to the nVIdia website, use their driver detection tool (it works really well for me) and download the latest drivers for your laptop.

I did this on mine and it solved loads of problems, including Blue screens when locking windows.

Original Poster Here: Not overheating!

by aspacecake In reply to Laptop Does Not Detect GT ...

Really sorry that i forgot to mention earlier, but it's definitely not a case of overheating. The laptop is always very cool and the fan runs well, ive felt the cooling vents in events of sudden shutdown.
I formatted it because i was having terrible load times in online games, always the last to load which was not the case a year back when i purchased it. Since formatting it runs much smoother and my load speed is good. I mostly use the laptop to game, so all my shutdowns occurred while gaming, not sure if related though.
I'm trying the nvidia drivers as suggested by Slayer_, will update if i dont crash ever again, thanks for the help all sorry i made this thread so long

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) ?
