New to me PC... powers on but won't show on display.

[Uncle Iroh]

Hey everyone, my gf just bought an old PC from her friend to play stardew on. I had to do some work to it before we tried starting it up and we can't get it to display anything.

 

Looks like an athlon 2 based on the pin layout that I had to straighten some pins on, 16gb RAM, non modular evga power supply, amd equivalent of a gtx 750ti, and 1tb wd ssd and hdd.

 

I have a spare pc I tried swapping parts from to Diagnose the issue with no luck. Tried swapping the graphics cards, ram, monitors, swapping between display and hdmi cables, pulled cmos battery. PC powered on and all fans spun up and slowed down like they should just kept saying no display signal. Only thing I didn't try was a switch on the back of the power supply that said 115 or 240.

 

Any ideas appreciated!

Yeah, stick to not trying this!! If you do, you will break something.

 

I gather the CPU pins survived the repair? If they are still intact, it should be ok.

 

When you say you tried swapping parts, do you mean you tried the GPU in the other PC and tried the other GPU in your gf's PC, or just one of these? If just one, try the other. Same goes for the RAM.

 

It does sound like it might be the motherboard. Does it have speaker pins on the front panel connector (where the power switch and LED connect)? If so, and if you can find a small speaker driver or circular beeper thingy (brass-looking circle with a smaller circle of what I think might be white ceramic on top), connect them up to see if you get an BIOS boot codes.

 

Forgive me if this question insults your intelligence a bit, but if it is the solution, there's no way to get to it without asking, so: you're not connecting the monitor to the motherboard rather than to the GPU, are you? 

 

You could try getting a can of air (or an air compressor, if you have one) to blow any debris from the slot on the motherboard that the graphics card plugs into. Don't blow your breath in there or you might make the situation worse.  A vacuum hose plus attachment will probably fare well too, though try not to knock anything with it. A hand held one may be a better idea. Do the RAM slots too. Maybe the CPU socket if nothing else works. Just be very careful.

What CPU?

Ok so is your power from the wall 120v or 240v? Because if that is/was set wrong and ypu tried starting it that way you basically killed the system.

So did you try it before doing that? If not you have no idea if it worked or not.

 

Basically sounds like the board/cpu/psu has gone up and died but hard to verify. Either way no loss as 50$ on ebay and you got a better core pc to put the 750ti into.

 

Hope you didnt pay much if at all for it as a athlon2 system is literally free to get these days
