Hi there Ivan, thanks for answering!
To answer you:
1- I've installed Windows 7 Home Premium, the original version that I had when I bought my PC. The CD came with it.
2- It's Admiral model and I have an Intel(R) Core(TM) i3-2100 CPU @ 3.10GHz. 4 GB RAM memory.
3- It was working perfectly, once I had to format it because of my stupidity I installed things that shouldn't (chinese applications) and I was full of viruses, but after that everything worked perfectly, I've even had it for years and it didn't make noise or anything like that. Only games slow me down, it doesn't have any damage. It seems to me that it needs drivers (this is what a friend who has little knowledge told me about), or maybe it's something else that I don't understand. For example, before when I wanted to record a game it didn't throw the fps down, I kept them normally and my game didn't get slow. After formatting the PC started all this.
I wonder what is due?
4- I didn't install anything when I formatted it.
Thank you for the information Derek004 and I apologize for the delay on responding to you.
At this point, I suggest you to install the latest Intel® generic driver, you can download it here:
Intel® HD Graphics Driver for Windows* 7/8-64-bit
You can use the .exe file for the installation process, if you get an error trying to install this driver, you can try installing it manually, please see how to Manually Install an Intel® Graphics Driver in Windows® 10 and Windows 8*/8.1*
I hope this can help.
