The other night I tried to start Windows. The start up screen froze, and the mouse, and what sounds like the fan came on strong and constant. lately I've had a lot of this over use of fan for prolonged periods, especially after a long session or when downloading. Seems unnatural.
So the only way to switch off was holding the start button for 5 secs.
Next day the same freeze, manual restart, this time I got a corrupt SYSTEM file in c:\windows\system32\config, and pc remained in DOS. All I could think to do was to go in via Recovery Console and TYPE the SYSTEM and SYSTEM.SAV files. The 1st was very different so I copied the .SAV over to SYSTEM.
This time I got further, to the Windows start screen but then it goes into Windows Installation mode and the fan goes mad again. It purports to have passed the collectiong info, dynamic update, prep installation stages and to be on Installing Windows. This happens incredibly rapidly (ie you don't see these stages - the screen 1st appears on this stuck stage)
Fatal Error dialolg comes up "An error has been encountered that prevens Setup from continuing. Internal Setup data structures are corrupted (phase 0)". OK to view setup log then cancel and it goes through the whole cycle ad infinitum.
I've caught the boot with F8 and tried "Last known good configuration" but no joy. I don't know how to get out of this nightmare. All I can do is switch off power. Please can someone help
