Ok. So my computer really screwed up. My computer has a backup in it to where if the notebook gets overheated, it shuts down without warning or letting me shut it down myself safely. Well, this morning, I booted up a high performance game (Sims 2 including all of the expansion and stuff packs ever created) and forgot about it and went to run an errand. What’s worse, is I had taken off sleep mode, so my computer could not enter sleep mode either after a certain time. Well, I got back just in time to catch my computer’s screen going blank and then the sound of the game stopped, which always indicates that the computer is shutting down. So, I let it shut down cause I had no choice. Well, I waited a few minutes and restarted my computer. I went to get a drink of water and when I got back to my room, I had missed the option to start it up in safe mode, so it started up in normal mode. That may have been why it messed up. Well, here is everything that was wrong with my computer once I typed in my password and logged in. First thing I noticed is that the computer theme was set to Windows Classic. I went to personalize and it wouldn’t let me access the ability to change it back to Windows 7 theme. Unfortunate. Then, I noticed that my sound appeared to be muted. I tried to go to the sound setting to unmute it, but it wont even register a sound card. Then, I realized that my internet was not up. It wouldn’t even let me access my network settings to check my networks. The icon didn’t even appear on the task bar. I couldn’t believe it. And, my screen brightness was set to really dim, so I couldn’t even hardly see the screen. Now, with all of that noticed and nothing to be able to do with my computer, I decided I wanted to install Lego Starwars III on my computer. So I inserted the disc, ya know, and guess what? It couldn’t even find and run the windows installer service, so that was worthless. So the only thing I can do on my computer is write in textpad and notepad, or play Sims 2 with all expansion and stuff packs. It wont even let me install Sims 3 after I downloaded it from the internet. So I have no idea what to do. If a smart computer tech can help me out, it would be really appreciated and it would help me a lot. If you can help me, I am using my sister’s computer right now, and I will not be on much, so I only have a phone that can connect to WiFi. An Android phone. It is powered by google, so you can answer on here, but also please e-mail your answer to glenny3214@gmail.com. Thanks so much if you can help and I am really sorry for the long question. And if you are a fast texter, text your answer to 1-507-216-3488. I have unlimited free texting all around the globe with the aid of an app for android called textfree. Once again, thank you so much. Your help is greatly appreciated, and I can help you with game downloads and torrents and serials for those programs if you help me and even if you don’t, just send me a message to any of the provided info and I will get back to you. I am a whiz at those. Thanks again. 
Peace and God bless. And I do know a lot about computer games and stuff like that, so if you need help, ask and I will help if I can. Once again, thanks.
And I cant reinstall the OS because it is only an update. See, each new OS is integrated with the previous Operating Systems. Lets say, there is 3.1. Windows has 3.1 integrated into it. 98 has 95 and 3.1 integrated into it. 2000 has 98, 95 and 3.1 integrated into it. See what I mean? To reinstall, I would have to start from scratch. Very bad, and I hate Windows 7 anyways. I have always had problems since day 1, but then again, my whole computer has. Anyways, that is mostly why Microsoft sucks so much. They never start from scratch. Bill stole ideas from Apple and each time they create a new OS, they never start from scratch. I believe that if they just scrapped their whole Microsoft OS layout and program and started from scratch and spent alot of time and effort designing, and then alot of time and effort programming and testing before releasing it and double checking to make sure it is flawless, they would have a real winning OS. See what I am getting at?
You should have made a system image for back up.
if not,
then i would say the best thing for you to do is re-install the operating system.
