Windows 7 won't Start up - Error code 0x490 and 0x00000050
Hi,
I am currently having issues starting up my laptop which is running windows 7 home premium. It gets to the 'Starting Windows' screen with the Windows logo and gets stuck (the windows logo is still animated it just does not proceed further). I have searched the Internet high and low including these forums for an answer and I've tried as many possible solutions as I could but I cannot figure it out!
How it started:
About 2 days ago I noticed my laptop slowed down quite drastically and so I launched task manager which showed the CPU usage was at about 30% with no programs running and none of the processes in task manager appeared to be responsible.
The start menu froze so I rebooted the computer by holding the power button and I have not been able to launch windows since.
I attempted to run safe mode but once it booted no text appeared and I then got a BSOD with the error code STOP: 0x00000050. I then booted it under "directory services restore mode" which worked and then safe mode worked after that, not sure why....
Also, under device manager I noticed that the "security processor loader" driver was not working correctly (error code: 24) so recently I uninstalled this driver.
Solutions Tried (roughly in order attempted and restarted after each attempt):
- Tried start-up repair many times but get an error "system files integrity check and repair 0x490 error"
- System restore
- Attempted a clean boot
- Did chkdsk /f from safe mode (returned nothing)
- Did SFC /scannow from safe mode (returned nothing)
- Scan with norton antivirus (returned nothing)
- Scan with malware bytes (found a program called 'greatest arcade hits' which I subsequently removed, I think I accidentally installed this when in safe mode after these issues)
- Updated my graphics and audio drivers - then uninstalled and re-installed them
- Disabled most drivers
My Laptop Specs:
- Samsung - RF511
- Windows 7 - Home Premium 64 bit
- Intel core i5 - 2.5Hz
- Intel HD Graphics
Is there something I am missing? I've tried everything I could think of doing, but I haven't been able to narrow down the possibilities at all and I'm running out of options!
Any help would be greatly appreciated!
Thanks in Advance!
