Ugh... To start at the beginning:
Few days ago during start up I experienced my first BSOD and it was INACCESSIBLE_BOOT_DEVICE. After few restarts system booted and I scheduled chkdsk /f /r (or the other way around, don't remember anymore), since that was what the internet told me to do. After another restart chkdsk picked up and promptly got stuck at 11%. Subsequent restarts
proved fruitless unless you count more BSODs, some times INACCESSIBLE_BOOT_DEVICE and sometimes IRQL_NOT_LESS_OR_EQUAL with no further description. Eventually booting would stop at manufacturer's (Lenovo) logo. So I took the blasted thing to a technician.
The guy told me almost at the door it's probably my HD dying. He later said he run test on all hardware components but they all seemed fine. So he hit recovery button (I forgot to mention that I tried that too with no effect) and it worked...
So he recovered original W8.1 and upgraded it to W10. And that's what I payed him for in the end :/
At home I decided to make a clean install of W10 since I feel no love towards all the crap Lenovo puts in their laptops. Went fine, system worked without a hiccup for about a day and... BSOD on a startup. And refused to boot completely.
That's when I decided to come for hep here, but had no diagnostics to show and no prospect of getting them without Windows actually starting. Then I thought problem may be strictly W10 related, so I hit recovery and got W8.1 recovered. Their were some more BSODs during the process but eventually I was in. I downloaded Sysnative BSOD Dump +
System File Collection App, made zip file, discovered Windows refuses to perform "permon /raport" because bleep me and started creating my post on this forum secure in knowledge that those crashes happen only on startup. I was just finishing my post and... BSOD. This time it was IRQL_NOT_LESS_OR_EQUAL related to mfehidk01.sys (only time it being so specific).
Sooo... Some digging and I found out about bootable diagnostic tools. Checked RAM - all fine. Tried to run SeaTools for DOS - couldn't see my HD al all (my HD is SeaGate). I found some tools from Lenovo as well. Made them check everything with no error in sight.
And then system actually booted again. I quickly downloaded Sysnative app and copied zip to usb stick. Perfmon /report kept screaming "you're not my supervisor!!!" so I backed off. System still refrained from crushing so I downloaded SeaTools for Windows and put it on Fix All Long scan. No errors. Test passed.
As of this moment Windows is on but I don't know for how long or if it will work when I try to turn on system next time. Any help will be appreciated.
