Hey
I came back home i turned my pc on.it jus't Doesn't open. I can still see the pc glowing blue,so it isn't completely broken. Does Anyone know how i can fix this/what i have to replace?

I assume you have no visual on screen.
Do you have any weird beeps coming from the motherboard speaker?
Which power supply do you have? (Brand + model + wattage)
Which motherboard, CPU, GPU do you have?

My pc starts completely normal.it just doesn't Connect to anything.the brand is medion. I have no idea how i can find the other information without the box of my computer.but it all started whenever i started using the hp x2301 monitor.first day went fine.second day this happened.i don't think it's a monitor problem tho.the monitor works with the ps3.

If you still have warranty, you should try contacting Medion for support. If not, there's no problem opening the thing up and look inside. It is weird for it to do it suddenly though. It could be a faulty south and/or north bridge chip. Does your sound work? You can also go into BIOS to see if there's anything weird.

It's really interesting that my old monitor isn't working with the pc, and my old pc doesn't work with the new monitor either. but my new monitor works only with the ps3.Maybe it's a problem with my monitor?

If your USB ports also stopped working, don't think it's your monitor. Does your sound work?

 

[Craimforce]

Yes

 

[NightAntilli]

Do none of the USB ports work? The ones in the back are also not working?

I think i fucked up with my settings. My video card probably does 't Connect to my monitor. I was changing settings on catalyst center. Now my video card can't handle my monitor. I read this on hp manual.i have to set my videocard resolution lower.Any idea how?

Before we get to that, boot in safe mode by mashing F8 before windows starts up, and selecting safe mode. See if things work that way. It should be possible to change the resolution there for normal bootup, but I don't remember how exactly.
