Pc won' start

[Stelios Kalogeropoulos]

Well, my brother told me that graphics broke at some point and ever since the pc only starts at the blue repair screen. I tried all options given but non worked, not even windows repair as a reinstall. I cleaned the computer from dust and replaced ram. Any idea? Btw a green screen also appeared at some point.

Thanks in advance.

Well, looks like your brother was right.

So you think that is caused by the graphic card?

 

[CountMike]

Well yes, those symptoms fit bad GPU. Which kind of computer is that ? Does it have monitor output on MB ?.

It is a desktop connected to a monitor via vga-hdmi output.

Aw, come on, give us something to work with !! Computer make, motherboard, graphic card, processor, things like that.

I appreciate your effort, i really do. The thing is computer wont start and therefore i cant give you the specs since i clearly do not remember by heart. The processor is i5-3570k, power is cx 600 corsair, processor is gigabyte ga-z77x-d3h and the card is radeon sapphire hd7870 ghz edition something.

Ah, OK that should be enough for now. Those processors and their MBs have video output so you can pull GPU out and connect monitor to MB.

I did remember that but i did not know that in order for the processor's gpu yo work i need to remove the main gpu first. So the plan for now is to try the processors gpu and see what happens?

In most cases BIOS disables onboard GPU when an dedicated card is installed. May have to reset CMOS between changes.

What if the computer is still not responding? How can i reset it?

 

[CountMike]

Well, you can't really reset it, only CMOS/BIOS.

How do i do that?

You could remove CMOS battery (a button battery placed somewhere on the MB) and/or find CLR_CMOS and reset it by shorting it's two prongs.
Just in case you can't find the manual https://www.gigabyte.com/Motherboard/GA-Z77X-D3H-rev-10#support-manual
CLR_CMOS prongs are just above Front panel connector in the right bottom of MB. Few seconds of connection with a screwdriver is all that's needed. Make sure computer is unplugged from power while doing it.

Alright alright, i did everything you told me still the same issue arises. Could it be that windows for some repair went corrupt? What if i re install windows from scratch? Would that work?

 

[CountMike]

Maybe just drivers.

Well, i guess i have nothing to lose at this point.
