So, I'm trying to fix this Lenovo IdeaPad V570 my parents have been using. Stock, runs Windows 7 x64, pretty much used almost exclusively for internet browsing + word processing. It's a few years old. Maybe a year older than that. It does run dual monitors to some ~20 inch Sharp led, I think.

Anyway:
-- Initially, the problem was it would boot and the task bar was completely unresponsive (an hourglass over any part of the taskbar).
--Then the next time I started it up, the screen would boot to black.
--Did a system restore in safe mode. Still black.
--Booted into safe mode (where everything is fine), ran the virus scanner, ccleaner, and malwarebytes. Nothing suspicious showed up. Went through the msconfig to check to see what starts with Windows and everything seemed fine. Looked at what was installed, uninstalled some unnecessary programs (nothing malicious and nothing new) and restarted.
--Took me back to the unresponsive task bar, which I realized was just a really slow computer. Like about 10 minutes to open up the start menu, 30 minutes to shutdown, etc...
--Ran SFC Scan 3 separate times (with rebooting in between), saw way too many problems, and we decided to restore to factory settings.

--Backed up the files they wanted (all documents and pictures) and I used the OneKey Recovery that comes in a nice little button on the laptop.
--Everything seemed to be working great. Went through the Windows 7 setup and the computer was running fine. Installed several essentials (web browsers+extensions, malwarebytes, google doc, vlc, java, uninstaller, etc). Still working great. Got rid of the bloatware which came with the laptop (Bestbuy thing, couple Lenovo programs) and it still was working.
--Decided to enter each newly installed program to enter the account details or go through the first runs/set ups to make sure there would be no hiccups.
Went through literally everything installed without a problem...Then I went in the excel version of Google Docs, and Chrome opened into a blank white page.
--FYI: I have yet to transfer any of the files from before the reset.
--Gave it about 5 minutes, tried clicked it off, eventually decided to close it via the Windows Task Manager and that took about 8 minutes to open up into an error telling me an error onw how it failed and couldn't open up. Upon exiting that screen, it took me back to the desktop which was right back into the insanely slow loading problem I had before the reset.
--Reset it and now it's booting back into a black screen again. Managed to get to the splash screen once to open safe mode again.
--Checked the SFC Scan, again, and this time everything came out fine.
--Still booting into a black screen if I don't enter safe mode. Which everything work normal in safe mode. As it did before the factory reset.

And that's where I am now. Any thoughts would be appreciated. Thanks.

Last time I Installed vlc (assuming you mean the media player) something snagged it as a virus, believe it was nortons or avg...cant say if it was a false positive or not (but if it got flagged, its going places that can cause problems)...but its the only thing that comes to mind right off the bat software wise from your list...other than that it may be an infected recovery partition (rare, but possible) or something even more unlucky (do you have external recovery for it?) I would try that along with a BIOS flash to the most current or exact same version you already have, downloaded on another PC and ran under the safest context you can (can't remember if BIOS flashes can be run under safe mode) and save vlc for last lol...may also be...

I know that's not much help, but I honestly don't have any better opinions atm. If anything does come to mind i'll be sure to post back.

Ran a memory diagnostics and it restarts via normal boot (where the pc is unusable for me) Seems to skip the screen where I can press f8 to go to safe mode. Ran it again and saw it with zero errors before the reset.

Looked online to boot into safe mode immediately following memory diagnostics and some seemed ot like memtest86 more so I ran that and it came out with zero errors.

Flashed bios and start it up, everything seemed to work alright (at lest I could open the start menu or a folder without the computer becoming unbearably slow), opened Chrome and the computer went to shit again.

Again, everything works great in safe mode. Not sure what that implies. Complete noob here.

Anyone with any other ideas?

You know what, my brother took a look at it, did the exact same things I did disabling the start up stuff and services (thinking the problem had to be there if it works in safe mode and I already reset to factory settings) except he also unchecked the disabled services, and now it seems to be working...

See if it stays working.

glad to hear it, I believe there's a listing of default services that come with each version of windows...I would try to find one for your's and see if anything should NOT be there. If you find it, there are either tool's or looking up the 'SC.exe' command would walk you through manual removal, can't say it would solve the problem if something actually managed to reach the BIOS or recovery drive but its a start. I'm going to lose this name and all the post's with it, so I hope everything works out. Best of luck.
programs can be tricky (but so can windows itself), it's extremely hard to tell what the cause of a problem is without actually being on or in front of a PC in most cases. Hope everything stays working for you.
