BSOD-Unmountable_Boot_Volume / Hangup Problem
Hello Everyone I am new to this forum.
I have a SONY VAIO (VGN-NW120J/S) that is currently running windows 7.
Computer has been running slow with slow startups particularly in the last year. Sometimes when i lock laptop and walk away when i come back it has been restarted or shutdown.
Computer began to run poorly for about 20 minutes, Started to browse msconfig to look for anything weird then computer locked up for about 10 seconds and I got a blue screen and a restart, will not make it to log in screen. Could not write down the codes with pen and paper. Now the bluescreen says UNMOUNTABLE_BOOT_VOLUME every time. Made it past log in screen a few times but screen only shows black.
Crashes every time during startup but when trying to boot in safe mode i noticed it has a hangup on CLASSPNP.SYS for a long time then it crashes. Startup repair didn't fix anything. Ran chkdsk and it locked up. ran CHKDSK again later on and got a new beginning message saying it needed to check for consistency and it deleted a whole bunch of things now it runs every time i start up in normal mode? ran memory diagnostic 2passes didn't see any problems. Ran startup repair again after chkdsk deleted things, startup repair took a very long time. All the tests said completed successfully error code 0x0 the last thing on the list said :
Unspecified changes to system config might have caused a problem.
Repair Action: System Files Integrity Check & Repair
Result: Failed Error Code: 0x45d
I was also able to write this down on a piece of paper.
Problem Signature:
Problem Event Name: Startup Repair Offline
PS3 - UNKNOWN
PS4 - 331
PS5 - AUTOFAILOVER

PS7 - NOROOTCAUSE
Not really sure what to do at this point, any help would be really great!!
