After a catastrophic BSOD Config.Sys shutdown, I tried everything available to get back up in recover console etc. - I finally used the Windows OS disk and was able to choose a three day old Restore Point. That worked, however, I was only able to get into safe mode........so, after an exercise in futility, I was ready to do a Repair Install / or / Clean Install. I put the Win7 64 Disk in and after loading files, it came up and said that there was only 256 meg of memory
and that Win7 required 500 meg minimum..............OK, I went to msconfig / boot tab / advanced options and the ram box only showed 256 meg. I changed that to 8000 (I have 8 gig) - but it would only change to 3194. I accepted that and Win7 started fine to desktop.
On the desktop - in Device Manager, it showed 8 gig installed, 6194 available - yes, I know that 125meg is used for services. I ran the Msconfig again, and it only show Max ram as 3194, not 8 gig. I then ran the memory test and all modules came back successful.
At this point, what do I need to do to fix this or MSCONFIG?.
Thanks so much and have a blessed one.
