Monitor & GPU issues!

[HazzaB]

Hello, this is my first post on here so I'm sorry if it's in the wrong section. I've been having a whole bunch of problems with my AMD Radeon HD 6670 graphics card and my Dell monitor which I don't know the model of. To start off my PC started to overheat and shut down every so often so I opened it up and cleaned everything out, to my surprise it actually worked. While I was cleaning it I removed my GPU and removed the dust from the fan as well, then I put it back in again.

Then yesterday morning I woke up and powered on the PC, the fans and everything else was working with it. However there was no display on the monitor, it just kept going into some sort of 'Power Saving' mode. I checked the GPU and the fan was working fine but I still thought it was the GPU, so I was planning on buying one after Christmas.

Then just now I remembered that I have a working PC in another room so I hooked it up to the monitor and plugged everything in and powered it on, but there was no display on the monitor, it just did the same thing and went into the power saving mode again. The GPU in this PC is integrated however my new PC is separate.

So basically I want to know what the problem is and how I should solve it. Should I go ahead and buy a new GPU for my PC or should I buy a new monitor? Is it the monitor, GPU?

Thank you,
I hope to get a reply soon

Since you have another Pc with which to try things you can swap monitors to make sure that both work on the other computer then take the video card and put it in the other computer to see if it will work on another motherboard. This way you can determine if it is the video card or not.

I only have one monitor but I will place the video card into my old PC and test it with that motherboard.

Okay, so I tried placing the GPU into another motherboard but it wouldn't fit, the case and motherboard are very old so guessing that is why the video card wouldn't fit.

Okay your problem is one monitor, so you can't test if the monitor isn't working anymore. Based on what you said (plug ONE monitor into TWO different computers and the monitor doesn't work), tells you the obvious IF you know the 'old' computer was working fine before? If so then the monitor isn't working. Your only other way is to bring the monitor to a friends, swap power and connector (2 seconds) see if it works while the computer is running. If not there ya go.
