I ran SFC /scannow and there were no problems. All my drives are Seagate and I have used their tools before now. In fact the last time I had any problems with a Seagate drive it turned out to be a messed up OS - So much for letting the wife and son please themselves on their PC!
Windows 7 drive - I have been on AH last night and got into a busy area - the PC rebooted. I re-logged but lasted about 1 minute or less after the re-launch into the busy area before the next reboot. All told about 4 re-boots so I had enough
and selected XP on the last reboot.
Windows XP drive - Flew around 4 or 5 sorties in all sorts of situations and quite a lot in really busy spots - Rock steady, at least I was able to enjoy myself for a bit
I checked the Nvidia driver version on XP it was release 275.33. The latest available for XP is 327.23 Interesting, loads of updates and I have ignored them all and have a stable XP! -its staying that way.
The driver I had for Windows 7 64bit was release 327.23 (Interesting that its the same as the latest XP 32bit one).I have found Windows 64 bit drivers for the 275.33 release and have installed them. I have not really tested in AH yet as it was only one uneventful and quiet sortie. I have checked the Video settings in AH and I have used the same in both installations so nothing different there.
For what its worth the hard drive with windows 7 on it has never previously given me any problems when I used it for XP and it still seems alright in windows 7 except for AH. - I may buck my one step at a time approach and try re-installing AH in Win7. Of course when I do find what the problem is, I have that sneaky feeling it will turn out to be something stupid I have done. - It was that way at work when some-one had a PC problem and nine times out of ten it was a user problem. Some of my colleagues got in the habit of calling me before our IT dept. because as one of the more able users doing the same job I was familiar with all the silly things they tried to do that caused a problem.
