No video with i3-2120

[yoi55]

I am troubleshooting an Acer AIO PC. It turns on, but doesn't display any video, monitor says no signal. The PC has an Intel i3-2120 Sandy Bridge CPU/GPU installed. My question is: could the GPU go bad and the CPU still function? It seems like it's actually booting because the HDD activity light blinks after a few seconds like it's loading Windows.

You need to check the connections of the cable at the Computer and Monitor. If they look fine and you have access to another cable, try that. I have not heard of any of those Integrated GPUs going bad.

I did check the ribbon cable from the motherboard to the monitor. It didn't look damaged, and I did unplug it from both ends and reseat. Still doesn't work.

Try a different cable, if you're using D-SUB or DVI, try using HDMI

I had something similar happen. Power light would flash briefly, case and PSU fans would spin, but no POST or boot. The problem was the power supply in my case. Do you by any chance have a cheapie stock PSU?

It is an All-In-One PC...is uses a built-in monitor. There is a small cable going from the motherboard to the monitor itself. It's proprietary...don't have any others to try.

I went back through this and you said the cable was a ribbon cable. That is a bit unusual for that. In fact, I have never seem one for the Graphics. I have seen then in the older computers that were PATA. Those things can be easily damaged. What is the model# of your Computer, I know it is an ACER? You may be able to get a replacement cable.

It is an Acer Aspire Z1620...an older model than what is currently available. Looks like this:

I am still looking for a solution for this. Can't find the video cable anywhere, except for one on Ebay that is being sold AS-IS...might be bad.

I was finally able to get ahold of Acer. They are sending me a new video cable. Shipping was 4x as much as the part lol, but hopefully that is all it needs. I will update when I receive and test it.

I have exactly the same problem with a Z1620 - did a new cable resolve the problem?

No, the cable didn't solve the problem. I'm pretty sure the problem is the LCD screen. The cheapest I could find one was about $200! The owner of the PC didn't want to put that kind of money into it, since he got it on clearance for about that price anyway. So, I can't help any more than that, unfortunately. But, that's the only other thing I can even think it would be, as any problem with the motherboard would cause the POST to fail.
