My computer won't boot

[Jhong]

I need help! My computer won't boot. I opened up the computer and I tried to reseat the RAM memory. Now the computer doesn't post. The fan turns on, and the power light comes on. I don't even get a bios setup screen. HELP ME!

The graphics card may have died or perhaps the power supply is failing. Can you post your PC specifications for us?
