Fresh Windows 7 install large performance loss

The keyboard and mouse are fine now but i am still getting frame drops in certain games and whilst using certain programs. overwatch or VLC media player for example.

When before they both ran beauitfully

Look for a graphics card driver update.

Already done and nothing seems to of changed unfortunatley =/
anything else i cna check for?

Did you open device manager to see if there is no yellow alerts?

apart from that I have tried many a thing to fix the issues with overwatch but the only fix I have found is to run it in fullscreen. which was never needed on windows 10.

Is this maybe just an os compatibility issue or something else?

You have 3 missing drivers.
Open device manager, right click on one - properties - Details tab - Right click on fist string - copy
Paste the string here. Is something like PCI\VEN_168C&DEV_001A&SUBSYS_2052168C&REV_01
Do it for the 3 drivers.

unfortunately I have tried to update them via a driver updater tool that I paid for and the only search that shows anything for them is just similar tools for auto driver installations which Is rather irritating.

I havent been able to find any direct (trustworthy) websites hosting the downloads.

Any ideas?

Sorry I didn't see that part of your post but the Mobo install disc is long gone now.

PCI\VEN_8086&DEV_2F9C&SUBSYS_2F9C8086&REV_02
