No no no, IDE is alright. In Bios you can either choose the old fashoined IDE setup or the newer AHCI, but both work, even for SATA connected drives.
I don't know what the problem is, but if you changed the IDE settings most likely you wouldn't even be able to log into windows. It could be you overclocking and yes, the BIOS settings resetting o.0
IDE is fine for HDDs (generally), but to realize the effectiveness of SSDs, AHCI is recommended, but you will have to enable it before you install windows, unless you want to traverse a long arduous process.
