I had built this comp from scratch. Installed everything and had it running fine for a few months. Only thing was that it would boot to bios menu and id select save and exit. Well I accidently hit load optimal settings and it messed up my comp. It doesnt boot and instead reads the "please select proper boot device or insert boot media". I left it alone for a couple months on vacation now I've tried tinkering with bios. Didnt work. I believe I had to tinker with it before to get it to install my os windows 7 64bit. Tried reattaching and unplugging sata and just about everything. Still not working. I'm sure it's a simple fix since I clicked accidently the reset button on bios but I cant remember what the correct settings are. My hdd and optical drives are recognized. I'm no tech or computer savy. Any ideas?
