Windows 7: Can't install Java because I deleted almost my entire PC

My PC broke a while back and I had it covered by warranty so I thought they were going to scrap it and give me a new PC (Like they did last time) but they didn't.. So before that I went to User > (Username) > and deleted every library inclkuding downloads, documents etc. Anyway, when they fixed this PC and gave it back, Java was uninstalled because I had deleted the files for it, so I went to go install it and I've now installed it 6 times and it won't register as being installed even after resetting PC. I went to control panel and deleted 6 different versions of Java including JDK, Jre whatever version, but still no results. Please help someone Thank you very much, This is the only time I've ever had to result to online help

bump

Please don't bump, particularly if your OP was only a couple of minutes ago.

Try this for starters: SFC /SCANNOW Command - System File Checker

Still nothing. I've got all my old things now like the libraries etc. All I need is Java

Not sure what you mean by "Still nothing". What result did you get (output from SFC)?
