I bought a new computer like 3-4 months ago and it was running really smooth, but last week i had a problem with the vga cable. I use a DVI->VGA adapter and my friend accidentally pulled it a bit too strong. the rear of the adapter got losen and it wasnt working. i had to buy a new one, and as soon as I turned the computer on after a week the graphics were all messed up, the screen was like stretched, most of the letters in games and web pages look blurry and small, circles look like ovals now.... also a really weird window pops every 30 min for less than a sec in the middle of the screen. It looks like a command window like the CMD one. When i play fullscreen games and i try to switch back to the desktop the screen just goes black for 3 seconds its really annoying and i dont have any idea what could be wrong. I dont have that much knowledge about tech and i was hoping that i could recieve an amazing response here if you need any extra info or system properties let me know i will be checking this post every day thank you for your time.
