Ok so not really sure where to post this, but I really need help. I was using AVG to clean out my PC to play games with a higher fps. I selected Hard Drive scan to check for any errors. It restarted my PC and started the scan. It sat for 11% for literally 5 hours, so I decided to turn it off and continue my PC tune up. I also stopped the superfetch service. (as I heard it makes for better performance) Now here's when things get bad, I was reading a tutorial on faster gaming experience, and it suggested the tool, GPU Tweak. Not knowing much about it at all I downloaded it and ran it and it asked to restart my computer. I did, and it never booted back up again. I turn on the power and after about 5 seconds the screen shows a slightly lighter shade of black for about 5 seconds, then goes back to black an sometimes even turning off. Even with the HDD and RAM removed same result. I know this is probably my fault, but is there any to fix this and keep my data? Also, Intel i5 is what I have.
