Black Screen of Death

Hi,

I've been fighting over 2 weeks now with this problem and after hours and hours of struggle I decided to look for a help.
I will be detail as possible and hope there is someone who can help me through this to fix the problem I have.

First here are my specs:
Intel i7 M620 2.67GHz
4.00GB RAM
Windows 7 Ultimate 64bit
GeForce GT 330M (1440x900)

My problem is rather deadly and I have no idea where it's coming form.
I'm getting a random black screen of death where the screen goes black and the computer completely freezes. I know the computer has frozen because my friends on messengers like MSN or on Steam client displays me as offline.

It's not frequent, but it seems it appears randomly WHILE I'm using Photoshop CS4 or RIGHT AFTER my video player, KMPlayer, plays a video file (The video shows for a second and my computer goes into the black screen of death).
Since it's quite random and it doesn't happen for the most of the time, so I cannot reproduce them to try new things such as playing a song to see if it stops immediately.

However, I realized a similar issue occurs when I try to play a few PC games.
I own about 350 Steam games, and I've tried about 200 games and here are the few games that suffers from the similar issue:

Audiosurf - ONLY HAPPENS on pro modes. When the level loads and the camera view moves to the player, there is a shutdown blink and the computer stops. No sound.

Worms Reloaded - HAPPENS ON RANDOM. Black Screen of Death.

Alien Breed 2 - ALWAYS HAPPENS when the game loads, shows the copyright notice at the beginning and right after that, Black Screen of Death. Since it always happens, I tried running a music on the background and the music playback speed goes beyond slow as it kind of sounds like a bzzzz noise and stops eventually after about 30 sec to 1 min.

Lead and Gold: Gands of the Wild West - ALWAYS HAPPENS when the game loads. Same as Alien Breed 2, right after the copyright notice appears there goes the Black Screen of Death.

Heroes of Newerth - HAPPENED ONCE out of hundreds of games (each game lasts about 30 - 60 mins). Random Black Screen of Death.


First thing you would think it's a graphic driver issue, so I've uninstalled driver completely and reinstalled with various versions; factory driver from the manufacturer, latest from nVidia, unofficial ones from LaptopVideo2Go, and NONE of them fixed the issue.
Of course, I used applications like Driver Sweeper to make sure I go through a clean driver installation process.
So I figured graphic driver wasn't the problem, but seeing the problem occurring while using a Photoshop questions this evaluation.


Now I really feel hopeless and am left with only frustration.
Please, I would provide as many details as possible so help me solve this issue.

Thank you so much in advance.

No one knows?
