I just got a brand new windows 7 desktop computer on Friday and all I did was download sims games that I own, avg virus software (the free version), and ccleaner. Saturday night windows did an automatic update of over 123 updates. The next day it said they had failed and it was reverting changes. After forever of waiting on the same screen (hours), I rebooted the computer. Over the course of the next few hours the computer wigged out, shutting itself off, refusing to open applications, blue screening, etc. I did several system restores and finally caught windows trying to do automatic updates as soon as the computer booted. I stopped the auto updates and it stopped crashing temporarily. I left the room and came back to find it had crashed again and was asking for the windows 7 disc to repair. I had a techie friend come over and he ran the repair, removed avg and installed avast antivirus instead. Computer works okay but now I can't get my Internet browsers to work. I have a full connection, not just limited. When I first booted it worked but within two minutes it says no data received. I checked the Internet options and the LAN settings fix, but the proxy box is already unchecked. Any suggestions? If you need specs, tell me how to do it bc I'm not too great at this part of computer knowledge. Thanks for any advice!
