My Family PC (in my specs) wont POST! Here's the story: I went into the BIOS to see what the RAM timings were. They were 5-3-3-10, which I thought could go down to 4-3-3-10 for DDR2-533 RAM. I was wrong: I changed the setting, and now it wont POST! I have to hold down the power button for a few seconds for it to even switch on! I've removed the battery from the motherboard, but I think there is also a jumper you have to disconnect as well. I have it switched of at the wall and I'm letting it sit there for a while with absolutely no power. On monday I had moved the RAM to Dual Channel mode, and dusted it, but it was running fine up until now. Basically: HELP!
