I have a problem with my Acer V5-431P. When I bought the laptop, I immediately formatted the harddrive and installed a clean version of Windows 8. Aside from an incompatibility between the Atheros Wifi and Windows 8, I finally managed to install it and it runs very well.
There is only one problem: the Intel VGA driver on the Acer website does not work. The screen is very distorted, and this is due to the driver because the screen works just fine pre-boot. I'm referring to this driver listed on the Acer-website:
|VGA||Intel||VGA Driver||220.127.116.1149||152.7 MB||2012/11/13|
My problem is perfectly described by this video: http://www.youtube.com/watch?v=-JOIdAK4kS4.
I found new drivers for the Intel HD graphics on the Intel website (18.104.22.16862), yet these unfortunately do not solve this problem. I hope someone at Acer is working on this problem, because I have seen many other people having this exact problem. Please help!

edit: So apparently the screen problem is due to the Secure Boot UEFI, for more details check out these links:

Well I finally managed to get everything working. I am now working on a 120gb Samsung ssd, with a clean install of Windows 8 OEM with no Acer bloatware and secure boot working.
Apparently, the screen drivers only work with secure boot on. This poses a problem, because secure boot UEFI will only boot from an original Windows 8 dvd, or at least an unaltered one. Yet without a modified iso, the installation will fail due to the incompatible Atheros wifi drivers. Therefore you need:
The solution is to follow these instructions: http://answers.microsoft.com/en-us/windows/forum/w
The only exception is to
Note: To install Windows 8 retail or 8 Pro, you need to make an additional step as detailed in my previous post (the ei.cfg solution)

sir I removed the wireless card and installed an untouched Windows 8 OS, everything worked fine even with the Graphics... before attaching the wireless card I tried installing a lot of Atheros Drivers, from Wireless LAN_Atheros_22.214.171.1249_W7x64_A to Wireless LAN_Atheros_10.0.0.217.v3_W8x64_A but I'm still getting the same error with the card installed... please help me what correct driver for the wireless card I need and where I can download it... Thank you very much, I have been working on this for 2 days now...

If you have your serial number you can acutally find all necessary drivers on the Acer website. Feel free to post it here and I'll point you in the right direction.
Your serial number is under your device on a white sticker. It will start with either S/N: or SNID:
Either one is fine.

@ScottyC... already tried the drivers from Acer website using my SNID. Installing while the Wireless LAN card is removed (it's the only way Windows 8 will boot), after installing drivers I shutdown my laptop, intall the Wireless LAN card, reboot, BANG!!! I get the same error all over again (that's how I know my Atheros Wireless LAN card is the culprit)... here's my SNID: ********

Ok, lets get technical. Can you please go to your device manager, open display adapter drop down and right click on your adapter. Now go into properties. Click on the details tab and in the drop down select hardware ids. Select everything in this list and hit CTRL-C to copy it. Now please send that back to me. I will see if I can find you a compatible driver. If I have time I may be able to try and compile something for you, but I can't guarantee anything.
Awaiting your replay.
