Computer turns on, but nothing is displayed on the Monitor.

Last response: in Motherboards

Hi!
I have a Lenovo IdeaCentre K220 for a few years now. Several months ago, I was booting up the machine and accidently killed it during boot. Now, when I try to turn it on, nothing shows. I don't know what is wrong because I have tried different monitors, different cables, and an external graphics card! It still displays nothing. I've even reset the CMOS! But when I remove the RAM, it give's me the No RAM error code. Then, when I remove the CPU and have no RAM, it gives me nothing. It's very strange and even my Next Door Neighbor who is a Senior IT Architect didn't know what to do. He even did a 4 ft drop test and nothing came loose! So, can anyone help me here?

Thanks,
NetworkLabs

Hi, Without CPU you will not get any BEEP error.
Try inserting one RAM stick, install the graphics card, connect only the DVD driver, keyboard and mouse and test.

It's about 2-4 years old, so I don't have warranty. I guess I will try testing the power supply and replacing the RAM. Anything else I can try?

not really, you are at a testing phases were you need to test each thing individually
