I tried to play a game "Missing Information" half life 2 episode two modification running on the OrangeBox engine, and whenever I shined my flashlight at a character, the game would go freaky: everything turns white, blue lines ran up and down the screen, and the game would freeze. Pressing control-alt-delete about 5 times would close the game, and everything outside of the game would be fine. After restarting the game about 7 more times and still getting the same results, I gave up and tried an old Half-Life 1 Opposing force game. After playing for about 1 minute, the game would just freeze and close. So, I decided to stop playing games for the rest of the day.
Next day, I turn on my computer and very weird things happen! On the motherboard startup screen, there are orange and grey boxes everywhere, white algebraic equations running across completely black screens, and then blue lines scrolling up and down my screen past the login screen. I checked the device manager and it said that "NVIDIA GeForce 8800 GTX hardware could not start." (a picture is attached at the bottom of the thread.)
So, I did some troubleshooting.
What I did:
1.) Uninstalled the graphics card in device manager. Upon turning on the computer, Add Hardware wizard automatically came up saying "Found New Hardware: VGA Controller" every time the card was uninstalled.
2.) Uninstalled the Nvidia graphics drivers completely.
3.) Uninstalled the EVGA Display Drivers completely.
4.) Uninstalled DirectX 9.0c drivers completely.
5.) Turned off the computer, took out the card, cleaned any dust off of it and turned the newly found fan option from "low" to "high". After that, I put the card back in the machine.
6.) Reinstalled all the previously mentioned drivers again.
Upon turning the computer back on, I still have the same problems! I am so frustrated on what to do! The card in the machine seems fine! I would be very happy if someone can help me with this puzzling problem!
Also, here's some more information about the machine's hardware:
Intel Core Quad Core Processor 2.4 GHz
Asus PK5 Motherboard
500watt Power Supply
Gateway HD 1080p 1920x1200 Monitor
(Please let me know if you need anymore information!)
