- Machine Model Number: Lenovo G510 (20238)
- Specifications:
- Motherboard Model Number: Factory (LA-9641P HannStar), Actual (LA-9641P Palwonn)
- Motherboard BIOS Version: 79CN48WW(V3.07)
- CPU: Factory (Intel i7-4702MQ), Actual (Intel i5-4310M)
- GPU: AMD Radeon R7 M265
- RAM: 2 x 4GB DDR3 1600Mhz (8GB)

- History, Symptoms and State of the Machine:
- History: Some of the factory motherboard's components were fried, possibly due to overheating, but I'm not sure. The only difference between the factory and the actual motherboard is the vendor, which I purchased used from AliExpress. After replacing the motherboard, I couldn't get the laptop to boot; the screen was back, and the fan ran for approximately four seconds before shutting off, so I took it to a specialist, who fixed it by replacing the defective factory CPU with the actual one.
The laptop functioned flawlessly until I installed a fresh copy of Windows 7 and discovered that the AMD Graphics Card had vanished from the Device Manager shortly after installing the drivers. I double-checked the BIOS settings and found that my Graphics Settings were set to Switchable Graphics not UMA. I upgraded the BIOS to v3.09 and then reverted it to v3.07 after seeing no changes. - Symptoms: After installing a fresh copy of Windows 7, the AMD Graphics Card vanished.
- State of the Machine: The laptop is in fine working order, but getting the AMD Graphics Card to operate is critical because several of the softwares I use for my studies are dependent on it.

What are my options for resolving this problem?
Thank you!
