I've recently upgraded my old PC to a largely new one with an ASUS Z270-K mobo and an i3 processor. The old spec was a Core 2 Quad 9550 on an Asus P5N-D, running Win 7 which was fully updated.
The plan was to replace pretty much everything apart from the disks ( 1x 64 MB SSD 'system' disc and a 1TB disc for programs / data) and graphics card as I really didn't want the hassle of a clean install. The problem is the new system hangs and restarts at Windows start-up and in safe mode gets as far as loading classpnp.sys and then restarts. There's no BSOD in either case, just a restart.
Using a spare HDD I did a clean install and the new system is fine - so there don't seem to be any hardware issues. Equally the old rig still boots fine with the original SSD drive so the drive is OK and there's no file corruption.
I'm guessing this is a driver problem of some sort - either one's missing that it needs or one of the old ones isn't playing nicely with the new hardware. But as I can't get into windows I can't try to sort it. Start-up Repair cannot fix the problem and the log shows all error codes 0x0 until at the end it says:
Root cause found:
A recent driver installation or upgrade may be preventing the system from starting.
Repair action: System files integrity check and repair
Result: Failed. Error code = 0x490
Time taken = 224376 ms
Any ideas on how I can get around this? I know I can do a clean install but I'd prefer not to loose the best part of a day this will take. NB That System Recovery will allow me to get to command prompt if that will help.
