Ok, so about a month or two ago, my computer had a failed hard drive and I had to replace it with a hard drive in my old laptop, I tried to update directly from the HP website, but could not find the display adapter driver (Radeon 7450). Suddenly, I found out that windows could retrieve those drivers. Everything was retrieved (except for a PCI express driver), but all my games were laggy, unlike before my hard drive dropped. Later, I tried to update using Sim Drivers, finding the PCI express driver and upating the display adapter. After this update, I found out that my display adapter changed from being Radeon 7450m to Radeon 6400m series. I tried to backup, but it unfortunately did not work. Is there anway to fix this and solve the gaming issues?
Specifications:
Pavilion g6t-1d00
Intel i5 processor
Intel 3000 HD and Radeon 7450m switchable graphics
4 GB RAM
5400 rpm hard drive (Used to have 7200 rpm hard drive, if that would be a big difference in performance)
