Hello , i need help to figure out how to fix this super slow startup issue. This laptop takes at least 15 minutes to load before it gets to the log in SCREEN.. it was doing fine about a week ago where it would get me to login screen less than a minute before.

Here are the specs of this laptop,
Acer Aspire E15 , E5-571G-57LH
Intel Core i5 5200U 2.2Ghz
NVDIA GeForce 840M with 2 GB RAM
4 GB DDR3 Memory
1000 HDD
DOM: 9/12/2014
Intel HD graphics 5500
Windows 8.1 64bit (6.3 Build 9600)
BIOS v1.24
Directx 11

Now i'll talk about what i did with this laptop. When i found out this issue i tried to fix it, i thought it was malware/virus, so i did use malwarebytes to scan for viruses, but it still didn't fix the problem. So i thought if i system restore this back to several weeks back it would do the trick, so i ran system restore to an earlier point about 2-3 weeks ago, but when system restore is running , it had an error because it says it could not system restore as AVG has a file or something that was blocking it, so the restore wasn't complete. Next, i tried uninstalling AVG so it could system restore next time and finally i could restore it but the slow booting speed still exists.. as a last resort i ran reset my laptop to reset everything and now i have a fresh new laptop. but sadly the slow startup is still here... and that is the main issue, but there's also some side issues like windows explorer run time error occurring and the date of my laptop would jump 10000 or 20000 years forward each time i restart the laptop. the date jumping issue started when the system restore before was not complete.

These are the things i had done.. i really had no idea what to do next to fix this laptop If anyone can help me out here it would be grateful.
Please and thank you.

-TheeEDIT- update on the Time jumping issue

it was known that when windows explorer runtime error occurs, the time would jump forward in years. I had to use Ctrl+Alt+Delete to open TASK manager and manually restart windows explorer so i can click on stuffs again, and then i changed the time back.

When your PC stops booting, a boot drive is the electronic version of a defibrillator. If you can boot your PC, you can detect bad memory, chase bad sectors, change passwords, and recover data ... all the things you need to get the machine back to normal.  ...  make the boot drives you need.

So, is your problem solved?

I hope the fresh restore doesn't include AVG...they have really gone downhill in the past few years...

On top of the fact of being discovered as a data-mining component in their package...

thee1995, Do you have another PC you  can Use to make a USB boot diagnostic tool that boots up an alternative OS?
Here is what I mean:
