Help! Lenovo B570 Random Shut Offs and Start Up troubles

[BillRJohn]

My Lenovo B570 Laptop has been having problems lately. It's only a month old but has frequent issues.

My first issue is that it will shut off randomly no matter what I'm doing. I'll be online checking my email or whatever, then the screen is black and the power light is off. It's been happening nearly every day, and I'm going to college soon so I don't want it cutting out when I need it most.

My second problem is that occasionally when I start up the laptop, be it normally or after the random shut offs, it will not log in correctly. It happens whether I use the fingerprint scanner or type in the password. It will say "Welcome", then it will say "Please Wait", but it will not go away no matter how long I wait, and I've left it for 20 minutes like that before.

My third and most recent issue is that the laptop sometimes freezes or all programs stop working and remain unusable. When I am able to successfully start up and log in, I open any program and it will open, then immediately it will say "Not Responding". When this happens and I click anywhere else, everything becomes unusable, even the Start menu.

My solution to all of these problems has been to hold down the power button until the laptop shuts off, start it in Safe Mode, then restart it. I've installed McAfee antivirus and Malwarebyte's anti-malware software and scanned the entire laptop, but there have been no detections with either. If anyone has been having similar problems, and/or has a solution to my dilemma, I'd like to say thank you in advance.

Hi, try calling the lenovo support team in your country and tell them about your laptop's problem. i presume that since it's still new then it's under a warranty service. Also does your lenovo comes with a pre installed software? if it does then i guess you just need to bring it to the nearest lenovo service partner. I'm not sure though if reinstalling software is covered by a warranty service but the way i see it your laptop just need its software/OS to be reinstalled, properly.

McAfee, malwarebytes, and maybe your windows defender... are these antivirus and antispyware running all together on your machine?...then it could be these things that cause your machine to become unstable. Running these programs at the same time will cause conflicting issues on your machine. try uninstalling one of these and turning off the other and see what happens.

try to perform clean windows installation by pressing one key recover button first.

It has been doing this even before I installed the software. If fact, I installed it to try to figure out the source of the problem.

possible hardware or heating issue. try to flash bios update if you access windows otherwise call lenovo support line.

Thanks yigit. That seems to have helped. The random shut offs appears to have stopped, but the freezing after start up still occurs. I am suspecting that it may actually have something to do with all the antivirus and antimalware programs that I installed.

un-install antivirus and check if the issue persists.
which anti-virus are you using?

lenovo's basic parts and labor warranty does NOT cover software related issues. consulting them for this sort of problem (non hardware related) will get you nowhere. all they will do is try and sell you a software support warranty.

i suggest uninstalling mcaffee and that other one that you have, and getting AVG free 2012. i works great, scans fast, and it's free. also uninstall veriface if you don't use it. i think it might be what's making the computer freeze at startup.
