Upgrading an HP Pavillon model P6320f.

The old motherboard (Pegatron M2N78-LA) had a bad hard drive controller that was corrupting drives, so I decided rather than take that chance again and replacing it with a stock board, I purchased a cheap and cheerful Gigabyte GA-78LMT-USB3 Ultra Durable mobo and a 500W EVGA 80+ certified power supply.

The PC came with an AMD Phenom II X4 running at 2.8 GHz, 8 GB of DDR3-1066 RAM, and a 1TB Western Digital Green standard hard drive. I am currently using the Green drive in my gaming PC, so I stuck in a Silicon Power S80 240 GB SSD for the main drive, and a Western Digital Blue 500 GB 5200 RPM drive as extra storage.

This PC was my mom's and it all went south on her around 2011. The hard drive controller corrupted the WD drive even after checking it with a bunch of tools on Windows and Linux. She now has a newer H-P Pavillon desktop that is running very well on Windows 10 thank you very much.

Everything is running pretty well on this PC now. I was having problems with the fans running at full speed and sounding like a Kenmore upright vacuum cleaner. I replaced the stock 3-pin fans with 4-pin PWM Blade Master fans from Cooler Master. Everything is now quiet like church.

I also have a legit Windows 7 Pro 64-bit license purchased from ebay for $35 with an 80 GB older hard drive. ebay requires that a Windows COA be accompanied by some kind of hardware.
