One of the girls in the office has brought her home PC in for me to look at. Originally I the PC once logged in to Windows (7 Home Premium 64bit) had a script error come up from some installed software, now she has an issue with Windows not loading, so had the PC brought in so I can look at it.
PC goes through POST with no issues, and then sits there on the Windows 7 loading screen and does nothing (left it several hours). Next I tried to load safe mode, safe mode went through loading files and stops after loading "avgidsha.sys", great I thought perhaps and issue with AVG (she's running AVG2014), so loaded from a Linux Live CD and renamed the AVG folders and AVG drivers in C:\Windows\System32\Drivers and rebooted in safe mode. Safe mode then stopped on "classpnp.sys". I then booted the PC with a Windows Recovery disc and tried to run "sfc /scannow /offbootdir=d:\ /offwindir=d:\windows" which completed without error. I've also tried to enable boot logging/debug but no files are created, I don't think it's getting far enough in the boot process to generate these.
I've since tried, System Restore, Last Known Good Configuration and none of them allow me to boot in to Windows. Memtest86 completes without error (4 passes). I've run Western Digitals hard drive tools to check the HDD for errors and that completes without issue. I've reset the BIOS to defaults and disabled everything except USB and Windows boot still fails. I've changed the SATA controller to IDE compatibility and boot still fails.
I've recently tried to boot the PC using Herins BootCD running Mini XP, which also starts to load and then sits in the Windows XP loading screen.
Short of reloading Windows and hoping for the best I'm out of ideas on what to try next. I suspect I am looking at some sort of hardware failure but can't seem to pin point it?
Does anyone have any ideas?
*edit*. Doh, should have posted this under "Microsoft (Windows) Discussion & Support", would a mod mind moving it for me.
