Re: System corrupt...want to do full restore
Welcome to fixya
umm if you did not make any backup disk for your computer then there is nothing to be done at your home you will have to take to a service center
unless you know someone with the same computer type or you could try to reboot it with a different reboot /cd
i have a acer computer and i rebooted it with a reboot disk from gateway so this might work but not always

Use a Restore Point to go back to a date when this drive was working (you could have a virus, registry error or corrupt driver). If you do not have restore points set, then download and run the free version of malwarebytes, delete any viruses found, reboot the computer, go to Computer => System => Device Manager and right-click the CD drive name, and update the driver software.
There is a hard drive issue, or the window files are corrupt. The only option at this point is a full recovery of the operational system to factory setting. I hope you have the disc because it will prove if hardware is a problem or it will load up the way it suppose to.
This error is caused when your restore files are corrupt. If you have the system cd that came with your pc, you can restore your pc and the restore drive. If you do not have the cd, check Gateway's support website for restore ISO file for your model of pc.
Sounds like your hard drive has unrecoverable errors. If you have another computer available, download SeaTools for DOS and copy it to a CD. Boot the problem computer from the CD and it'll run a check to see if you harddrive's smartcheck flag has been tripped. If it has, replace hard drive and restore the factory settings using restore disk(s). If you don't have the restore disk(s), you can order them from Toshiba for your model for about $20.
If hard drive checks out w/out errors, you may be suffering from a virus that has corrupted files. The easiest and fastest approach is to restore to factory settings using the restore disk(s). If you haven't backed up your important data, download AVG with another computer, put it on a CD, install it on the problem computer, if possible, then start the problem computer in Safe Mode, then run the AVG program. It will default to batch mode when run in Safe Mode. If you have viruses, it'll get hundreds off your computer during the batch run. You may have to turn off Windows' System Restore first, to ensure the viruses don't get reloaded.
lsass.exe is certainly a virus issue, the actual process isnt really a virus but viruses hijack the process for their own nefarious reasons.
You only have two options really, 1) use a boot disk antivirus (search google for avg boot cd) and then use the restore disks to try and repair the system file (copy the one off the restore disk to replace the corrupt one on your system)
2) Use your restore disks / another installation disk to build a new operating system.
Just remember if you have data on the drive to take it out to get your data off first. Personally I'd take your drive out and put a new drive in, then build a new OS on the new drive, nice clean and fast, then put your data onto it.
Try rebooting in "safe mode".That virus probably didn't delete your virus protection,just hid it. http://www.computerhope.com/issues/chsafe.htm#03
Follow this link on how to get into Safe Mode.Then run your virus protection in deep scan to get rid of the nasty.
Your computer operating system is corrupt. Or maybe there is virus on your system that has made it corrupt.
Do you have any anti virus on your system? I will recommend that you try Avira Anti-virus. After you have installed the anti virus, use it to scan your system thoroughly and see if problem will persist.
If problem persist, then you will have to run the recover manager on your system. The recovery manager will help you repair and put your windows back to order, that is, to its factory default state.
Before you carry out the system restore, make sure you backup all your important files.
To do the system restore, click start menu, click all programs, look out for "Back up and recovery manager, click it and follow instructions.
