I'm sorry I didn't mention the up grades I did, before I installed Windows 10 (I just realized this was about old hardware compatibility with Windows 10). My computer has a build date of 08/28/09. The MB is a ASUS P5Q SE PLUS , CPU was a Intel Pentium D 3.00 GHz , 4 GB DDR2 800 MHz , Video Card was a GeForce GTX 8800 (I don't remeber, that may have been a upgrade), HHD 256 GB ?, PSU is a 375 watt ?
Years ago I put a GTX 560 in it ($100.00 used)
So before I upgraded to Windows 10 I put in a Core 2 Quad Q9650 3.00 GHz which I OCed to 3.82 GHz ($100.00 used) and a CoolerMaster EVO 212 Hyper ($25.00 after rebate)
Then after I upgraded to 64 bit, I put in another 4 GB of DDR2 800 MHz RAM, that makes 8 GB's.
(the RAM cost me a little under $50.00)
I had problems with Win 10 32 bit, screen freezes, losing video driver connection, and and other BS.
I just want to say it runs beautifully now. It's like a new computer to me.
Thanks for listening to me.
