|After trying the new sticks, I put the old sticks back in, in their original slots. Rebooted and got this|
Blue Windows screen, grey Windows 'Startup Repair' Dialogue box, saying
'Your computer was unable to start. Do you want to restore your coomputer using System Restore?
When I click Restore it goes into
Attempting Repairs ...
After about 5 minutes it gives me the message:
Startup Repair cannot repair this computer automatically
I click Don't Send and it says
Click Finish to exit and shut down your computer. I do this and the computer shuts down normally.
Then restartring it first goes to 'Starting Windows', this time with the colored Windows logo, then ....
Applying update operation 110 of 110 (Windows\ Registry [rest of the path I can't see]
Then goes to 'Preparing to configure Windows, do not shut off your machine'. It configures 100% and goes to desktop, fully loaded Win 7, all programs intact, and runs fine. After that, Windows restarts normally each time.
After that I tried just swapping the position of the original 2 and 4Gb sticks, in different slots and that also works fine and boots up to Windows normally. BIOS shows the original 6Gb, Win Sys info shows the original 6Gb. All is good there.
After that I re-tried the one new 4Gb, with the original old 4Gb, and this time it goes to Starting Windows (NOT the two choice 'Launch Startup Repair' \ 'Start Windows Normally' screen) At starting Windows, it just hangs. I let it hang for fiften minutes to see if it was just attempting to start, but no go.
Then I tried the new 4Gb with the old original 2Gb to see if that would work. It goes into the black screen with the two choices:
Launch Startup Repair
Start Windows Normally
CLicking 'Launch windows Repair' (default choice) it goes to
Windows is loading files...
Then goes to a completely blank black screen, where it hangs indefinitely. However, rebooting into BIOS it does show 6Gb (6144Mb)
Then I swapped position of those two sticks into different slots (new 4Gb and old original 2Gb) and got the same result, either a loop of the two choice window, or a hanging black screen.
Then trying the new 4Gb alone, I first booted to BIOS and it showed up as 4Gb alone. It got to the two choice screen. Selecting Start Windows Normally, it went into the dreaded blue screen saying 'A problem has been detected and Windows has been shut down to prevent damage to your computer IRQL_NOT_LESS_OR_EQUAL'
Rebooted and selected 'Launch Startup Repair' at the two choices and it went back to the blue screen, with suggestions such as verify the driver, run safe mode, or disable and new hardware.
And finally, I tried just the old 4 Gb alone it booted first into system config, the normal to Windows.
Returned to my original 2 and 4Gb RAM and it worked
So about all I can conclude from this is that the new 4Gb is either incompatible or a bad stick. A couple questions ....
If the new 4Gb, paired with the old 4Gb memory, does show up as 8Gb in BIOS, but still won't load Windows, can I conclude that the machine will indeed take 8Gb, but just that the new memory is hooped or incompatible? I know that particular memory stick won't run, but my question is more about determining if the machine will for sure take 8Gb. I still haven't ruled out that even if I get a compatible new 4Gb stick, the machine will only run with 6Gb.
I'm gonna take your suggestin now and go to crucial.com to get a scan. I'll let ya know the results.
And thanks for your input Fingers
