I hate to say it, but you may have gotten scammed. Whenever I get this error, it just means that the boot priority in the bios got reset somehow. Most board do not default to the HDD as the primary boot device, so if the boot priority gets reset to the defaults, you will get this message.
The fact that you cannot get into the bios is odd, however that may also be the default. Most bioses let you turn off the prompt for entering the bios and IIRC, in some cases you can turn this off entirely. In that case, you need to do a bios reset. I’d explain how, but I guess it’s moot at this point.
Replacing a m/b presents a few problems to the newbie.
- application of thermal past to cpu
- proper seating of heat sink on cpu
- connecting fan of heat sink to proper terminal
- proper seating of memory modules and PCI cards
- connecting front/rear panel indicators and input/outputs.
None of these is a big deal if you know when something is done correctly and when it isn’t.
I could probably talk you through it, but not being there means I might tell you the wrong thing. Feel free to pm me though.
There is also the issue of re-installing the OS. I’ve done this many times with Windows XP and once so far with Win7. It’s not pretty, but it generally works.
As for recommendations, I only found one board on new egg - http://www.newegg.com/Product/Product.aspx?Item=N82E16813157162
The problem is that micro-atx boards tend to only have 2 memory slots.
