Please check if this internal driver is compatible for my motherboard

My internal hard drive is failing and don't know if the internal hard drive Im going to buy is compatible.

It should be compatible, but have you considered installing a Solid State Drive (SSD) instead. SSDs are more expensive but the speed increase is quite amazing.

There are many brands available & Samsung is a good brand to look at. Search the internet for SSDs & read through the specs & then you can follow up on pricing & suppliers.

My MB is only Sata 300. Will it work?

Yes, a SSD will work on your computer. Even if your SATA is 3.0, it will be 3x faster than a HDD.
If you want a lot of space, you can buy a small 120G SSD for Windows and programs and a HDD for data.
As you have Win 7 32 bits, adding 2G of memory will also be good. Try to buy same brand and model of the existing memory.

Generally, any SATA hard drive or SSD will work in your computer. All of the current drives are backward compatible to SATA 3.0.
