Laptop no longer getting past Start Up Boot

Hello, I had a problem where my windows 7 64 bit laptop hasn't gotten past the start up screen for well over 20 minutes. I've powered off my laptop and attempted a startup repair 3 times with no improvement. When the startup repair completed, the diagnosis showed that the only repair action that failed was System Files Integrity Check and Repair with the error code: 0x490. I've also attempted restore my system up to 3 days ago however the problem persists. Any further attempts at using the Startup Repair I get a message saying "Startup Repair cannot repair this computer automatically". It then provides the following problem signature:

Problem Signature:

Problem Event Name: StartupRepairOffline
Problem Signature 01: 6.1.7600.16385
Problem Signature 02: 6.1.7600.16385
Problem Signature 03: unknown
Problem Signature 04: 21200100
Problem Signature 05: Autofailover
Problem Signature 06: 4
Problem Signature 07: NoRootCause
OS Version: 6.1.7601.2.1.0.256.1
Locale ID: 1033

I've managed to successfully boot into Safe Mode with Networking and opened up the elevated command prompt and then ran system files checker SFC /scannow hoping it would fix any of my startup issues. However at the end of it I got a message saying, "Windows Resource Protection found corrupt files but was unable to fix some of them" and left the file sfcdetails.txt of what went wrong. The only error I noticed regarded a file called "ksuser.dll. Do I have to find a non-corrupted version of the file and replace it to fix my start up problems? Any help would be greatly appreciated and thanks!

I don't know how to fix these problems but only corruption is ksuser.dll. Will ask NoelDP to take a look. Hopefully, he will guide you.

Did you go through Troubleshooting Windows 7 Failure to Boot yet? Might have some steps you have not tried.

Thanks for the quick reply. I haven't attempted most of those yet and will definitely give them a go now.

Eurim, I think you could save yourself a ton of grief and time buy backing up all data and as long as you have your system disks, drivers and OS or even just the key for your OS you may want to just bite the bullet and do a clean install. There's a great tutorial on that right here. Please use this as a chance to minimize bloatware and this wipes your drive so you are like starting over with in many ways a better than new computer. Also pull the back panel and blow out the fan and coolers, maybe add a ssd and more ram after you tweak your rig and fresh install you'll get back your snappy new computer and can move on.

Thanks for the response. Im currently in the process of reinstalling windows 7 and I'm a little confused as to when it actually completes. I've restarted multiple times already and I've even reached the point "completing installation". My laptop restarted again, brought me back to the main installation page with the install now button again. Is it done yet? Can I cancel it, eject the disc, and try to start up my laptop normally or will I lose all I installed so far?

EDIT: Well I figure out what the issue was and solved that part. I did notice that when my laptop restarted it gave me the option of choosing between two Windows 7. How do I know which one to get rid of?

Also, I can't connect to the Internet due to lacking drivers. How do I know which drivers I need to install and where's the best site I can get them from?

If you can provide the exact make/model of PC, we can find it for you.

Don't worry about the 2nd Windows install at the moment. But please backup all your personal files (music/documents/pictures/emails if you use a client/etc.) as soon as possible to an external drive.

This should be the current laptop I have. When I ran dxdiag it said the system model was 700Z3A/700Z4A/700Z5A/700Z5B.

Scroll down to "Manuals and Drivers", on the right side Downloads - "View All", click and select drivers.
Scroll down again until you see Windows 7 drivers - get "Wireless LAN, INTEL" with the matching bit version.
Also get the "Lan" driver.

First finish Windows Update updates (get optional updates too, drivers are in this category) - manually check for updates until none are offered. If you still have missing drivers then go back to support site.
