Sorry about this , 2 slight problems, you may be able to help me fix,
I have 2 hard drives - c drive 160gn, and an additional internal 1 x 500gb.
I took the 1 x 160 main c drive out and replaced with another 500 gb, installed x64 bit win 7 on the main 500gb, FROM a 32 bit version - hope your still with me !
I can see a slight difference in performamnce, but it still shows only 3.5gb of RAM used out of the 4.0Gb RAM I have installed, I thought with 64 bit installed it should show the whole 4gb working.
The 2nd issue is, i can only see 1 x 500 gb under my computer, which the win 7 x 86 (64 bit) is installed, but under HDD Diagnostics test, shows 2 x 500 gb drives both working correctly, how comes I can only see the c:// 500 gb drive.
Ps i do not hope it has isnatlled windows over the old 500 gb and it's not showing the new 500 gb !!!!, as i've only partially back up the data on the additional drive !,
corr, i've lost the plot writing this, I do hope your understand.
I agree with MAT ALAN - I think you have installed a 32 bit version of Windows 7 - you can't install 64 bit from a 32 bit version. If you installed from a Genuine Windows 7 CD you would have 2 versions on that CD to choose from - is it possible you have done it this way and installed the wrong version ?
