Neighbour has a problem with his PC (E Machine with Vista basic on it) NTOSKRNL.EXE becoming corrupt.
I will try to explain: He can boot up ok, but if he does a restart after he tries to install any Microsoft updates, during the shut down, gets a screen saying, configuring 1 of 3 updates, and the 1st one takes about 3 mins to configure, the 2nd about 30secs, the 3rd doesn’t get touched, it carries on shutting down, on reboot, after the windows screen, up comes THE TECH GUYS, (E machine remember) saying it has to do a Microsoft windows repair, and does it, then a little window comes saying finished, and when you look at the log it says NTOSKRNL.EXE was corrupted, and this happens every time he has to reboot.
The reason he has to do this is because some of the updates do not down load to the PC, after down loading from Microsoft, it’s the same ones that don’t, tried with AVG and Defender off, but no joy. The same thing happens every time.
Tried your suggestion but pressing F8 only goes into safe mode,and the first thing that is high lighted is Windows Repair, and if you press that it only goes to the Tech Guys, and on a closer look there is a question with with a radial on it that says: Destructive Repair (or Recovery)?. does this do the same as using the Discs.I.E it goes back to the factory settings??.
