I recently did a fresh install to a Sony Vaio PCV-7753. I then went to the Sony website to download the drivers. There's a program that sony has called, "Download Taxi". I entered in my model number and it gave me a list of three different models that my model could be. I then went back and used their program to find my model for me. After doing so, I installed Download Taxi. I used this to download all the original drivers. After downloading, I installed all the drivers.
After installing all the drivers, I noticed that the screen resolution was crap, so I went to check the hardware profiles. It seems that the video driver didn't install. I figured maybe they searched and found the wrong model, so I tried to manually install the driver by findind the name. I opened the thing up, integrated. So I go back on and select the other two, one at a time of course, both installations didn't work.
By the way, I was prompted that a restart was required but it didn't restart for me after I click yes. So I waited a few minutes and restarted it manually.
