my laptop keeps restarting by itself?

Question

my laptop was working perfectly untill i set up backup and installed avg. i also unistalled crome and firefox (firefox i had installed before because my flash player kept crashing on crome) and installed internet explorer. internet explorer was having problems loading pages and was very slow so i re-installed crome. ever since i installed AVG and made these changes my laptop has been starting up extremely slow (some days it loads fast other days it doesn't load at all and freezes) today while i was watching a programme on 4od my laptop suddenly closed down and a message screen came up telling me windows had failed to shut down (even though i hadn't pressed the off button or shut it down), i restarted windows normally and carried on watching 4od and it turned off again, this time i started it in safe mode then in normal mode but my laptop would not load completly and would freeze. this is the first time i've managed to load up the laptop without any problems.

1. Go to safe mode and start System restore. Select a date where you know you laptop was working perfectly. and choose that and continue.

2. If System restore doesn't work the you will Uninstall AVG, Uninstall all other Application you installed before having issues.

Answer 2

Well i think you have a virus so download malware bytes and i know you cant so just get a USB and putit in your laptop and install it. if for some reason you cant get malware then delete that AVG thing and stop installing and uninstalling stuff that you downloaded. that might be the problem. so if some resason malware or deleting AVG doesnt work then ask someone you know who could restart your computer(meaning that everythings gonna be deleted and turn to like a new laptop) and thats all i got for you. Hope it works.

This sounds like one in each of two issues. it would desire to be a scourge - attempt working a Norton or Macaffee programme on it to confirm if that clears it up. Will it aid you start up in secure Mode to debug? may well be properly worth calling the producer. in any different case it would desire to be that there is something incorrect on your BIOS setup, which you will be able to go into by utilising urgent F2 (that would variety from workstation to workstation) and look at it. this is particularly easy yet is tremendously plenty the workstation's cerebellum! It controls the fundamentals like the workstation's inner clock, and what sort of secure practices settings you're working. people tend to forget approximately this section now as maximum of those applications might properly be controlled by homestead windows or your working device. attempt this internet site - it explains BIOS and what to do with it in extra element - yet confirm you rememebr what you have replaced as this is going to likely be common to the device.
