This problem started about two months ago when my computer wouldn't make it past the splash screen. I tried everything! The computer wouldn't even load with the windows 7 disk. Finally I decided to wipe the harddrive after backing it up manually. This aloud me to install a fresh copy of windows 7. So the computer starts working all fine for the next month until recently. It has constant freezes randomly while surfing the Internet or playing games. After a few freezes it stops loading past the splash screen again. A fresh copy of windows resolves this issue but only for a few days. I have run full system scans, malware bytes, and memtest for over 12 hours. Can't find any errors.
All I do with this computer is play League of Legends. The only aftermarket part is the graphics card which is an AMD 6670. It is an Acer running windows 7.
It did seem like it was fixing things. After the scan the computer ran fine until it went to sleep and the display wouldn't turn back on. After restart it has been a little better about the frequency of the freezes but they still occur sometimes. I will look for a new SATA cable and switch ports. Maybe on payday ill pick up a new HDD.
