i5 3570k on a MSI z77a-gd65

I have overclocked before, but am not an expert. I followed a couple of different methods for this board, and the BIOS says it's overclocked. But when i get into windows all of my monitoring tools say I'm at stock speeds. If I'm really fast on boot up I see my OC speed in realtemp, but it drops down to stock within 1 second. I've tried CPUID and HWmonitor as well, and stress tested with prime95. All show the stock speed. If I click on properties of my computer I see my cpu, the stock speed, and the OC speed. But it's not actually using the OC speed.

Thanks in advance for any ideas. (I took a screenshot last night of all these things, but evernote must not have had time to sync. I'll post one tonight)

Also, this mobo was used for 8 months with a cheap celeron processor. I just bought the i5 and installed it this weekend. Any one think i have to reinstall windows?

I don't think Windows is the one to blame, if you overclocked properly, it should show on CPU-z(cpuid). There is a bracket to show the clock range, for example, if you overclocked to 4.3ghz, it would show (8-43) which is the range, when idles, it would use only 800mhz instead of overclocked rate. If however you only see (8-35) which 3.5ghz is your stock clockrate, then you did not OC it properly.
Knowing that you have a new CPU, and an old board, I would update the BOIS first, and try OC again, yes, I recommand you reinstall your OS, but I don't think you have to. It's up to you.
