There's a weird switch next to cpu

[Frecsh]

I accidentally hit the switch when I was cleaning my pc. I'm using an ASUS MSA99FX pro R2.0 and an AMD FX8350

I have no idea which switch you're talking about, but check your motherboard's manual to find out what you've switched.

Switch or button? If button next to the ram slots might it be the "mem ok button",that would do no harm
