I've got an Asus Zenbook UX32A and I've got a weird issue where sometimes when I start it up, or switch the screen off, or close the lid, etc. the screen won't show an image, the backlight will be on but it'll just be a black screen, I've tried reinstalling windows, I've tried a different version of windows, I've even installed windows on a different drive and still it happens, I was wondering if anyone had any idea what it could be or how I could fix it? It's been happening since I got it but I think it's more frequent now, and it's no longer covered by the warranty.
Spec:
i5 3317U
4GB RAM
500GB HDD
22GB mSATA SSD
OS's I've tried: Windows 7, 8, 8.1
