The Windows 10 computer has double the RAM and an SSD but the windows 7 one seems to be much faster. These are the basic specs using speccy. A friend is selling it and I'm consider buying it and putting my hard drive in from my win 10 laptop.

If it is your intent to transfer the hard drive with the Win 10 OS on it, install it into the Win 7 computer & run the Win 10 OS as is, you will most likely be dissapointed.

Generally one cannot take a hard drive from one computer with an OS installed on it & expect it to run flawlessly on another computer. You may be better served

staying with the Win 7 installation & doing the upgrade to Win 10 when it's offered.

I would most certainly create the recovery discs if possible for the Windows 7 computer before installing any upgrade to Win 10. Additionally I would check the manufacturer's

support website & verify that the computer has driver support for Win 10. Microsoft offers the upgrade but they have no clue & could care less if the upgrade might trash your computer.


I never make the same mistake twice....I always make it 5 or 6 times just to be sure!

I am suspecting some sort of driver issue, sometimes the latest OS doesnt work with certain hardware due to compatibility with drivers.

Windows 10 is still wet behind the ears, for me win10 is speedy compared to win7 but that doesnt make all windows 10 installations the same.

What works great for computer a doesnt mean computer b will be the same

I would suspect the difference in the speed of the two i5 processors would be the reason, 2.50 GHZ as 1.70 GHZ.

And as well as the CPU clock speed, 2520M has double the cache, and GPU clock speed is very different, 650MHz for the 2520M compared with 350MHz with the 3317U. So video will seem sluggish on the Win 10 system compared with the Win 7.
