Hello :) i've had multiple problems with this laptop this one I have no idea to what could have caused it, ive never had it before... I have a Dell Inspiron 1525, I was on it last night, hadn't installed anything, just turned it off to go to bed but then I woke up this morning and turned it on but it wouldn't load up, Just got to Microsoft corporation and stayed there no matter how long i left it, I ran diagnostics and it came up to say that there had been a recent change to my hardware or something. I haven't done no updates recently as there hasn't been any. Couldn't get into safe mode, same problem as trying to start normally. Finally got it to load onto the installation/repair disc but when I ran the repair my computer and it came back saying startup repair can't repair it automatically.
I can't say exactly what it says as it would take far too long to type and I'm using my phone to write this. It just says all tests preformed completed successfully but one and it says / Root cause found: Unspecified changes to system configuration might have caused the problem.
Repair action: System files integrity check and repair
Result: Failed. error code = 0x490
Time taken = 473182ms
What should I do next? Replies would be appreciated. Ty! :)
