Solved Can’t access BIOS menu on Gigabyte motherboard

I just got a new Gigabyte H61M-S2P motherboard and found that when the computer starts there is no POST screen that tells me how to enter BIOS and all. I ignored it because I didn’t need the BIOS. But it all happened today, I left my computer on and went to do something and when I came back I found a message saying there is no storage device and when I pressed OK it went to the BIOS menu by itself. I know what the whole no-storage-device thing was, I just adjusted the hard disk cables and it worked, but let’s go back 5 minutes before that. I found an option to change the amount of Internal Graphics Memory, it was set on 64MB (I’m using the onboard graphics card) I didn’t know that the dedicated video memory could be changed so I changed it to 1024 MB (Yes, I know it’s stupid now but didn’t know then). The problem is: I have only 2GB of RAM and now it’s 1GB due to the increase in the graphics card video ram and I can’t reenter the BIOS to readjust it.
