1. Connect PC to wireless network from mobile phone (iPhone).

2. Go to sleep mode from windows.

Weird PC behavior.

Hello fellow forum members. I have a strange PC case to share with you all.

It started when I loaded Dota 2 and bam! the game crashed with the PC frozen. After a hard reboot, Windows booted (obviously) into 'Safe Mode'. During the safe mode screen, I noticed the display/graphics were a bit corrupted with a green/cyan tinge on a few words. Also, during the Safe Mode loading screen the blue 'Welcome' screen was tearing. After the safe mode loaded, I just browsed around My Computer etc, and noticed the window panels that had blue shades or backgrounds were tearing as well. I doubted it could be the bad video card drivers, so I clean uninstalled the gfx drivers and rebooted windows. This time, Windows loaded into its usual Normal mode, however, the aforementioned screen tearing of the Welcome screen, window panels with blue color continued the tearing scenario. Then I loaded the prior version of the gfx drivers and rebooted windows. This time instead of loading windows into the normal mode, my computer froze again with no display on my monitor. The keyboard was unresponsive. Although I waited for a 10 mins thinking its taking its own to load. But I had to do a hard shutdown/reboot.

Summary:
> Windows loads into Safe mode with screen tearing.
> Windows refuses to load in Normal and a blank screen is seen.

System -
Windows 7 (SP1)
8 GB RAM (Dual channel)
AMD FX 8320
Sapphire (AMD) 270x 4GB
MSI 990 FXA

Steps tried -
> Rolled back drivers to 16.xx from 17.xx
> Opened the hood and re-dusted off the video card.
> Reseated the video in the second PCIe slot.
> Reseated/Swapped DIMMs.
> Powered my laptop and posted this issue on these forums.

What could be the possible cause? I'm experiencing this issue for the very first time. I have little knowledge of hardware as I've custom built my own desktops.

My PC was working fine till this afternoon. Any help/suggestion is appreciated. Thanks for your time!
