Does it mean Gpu is broken?

Does it mean GPU is mechanically crashed, or can this be a software issue?

You will have to provide more detail, especially what you are trying to display there. For all I know, that's the image you are trying to display - it looks like flight control radar.

My best guess in this case is that your display is physically broken. Not the GPU, the physical display. Can you please post
1) Complete hardware specifications? Make and model or, if home-built, the parts
2) A link to a web page and a picture of what that web page looks like full-screen on your machine, so that we can compare what we should see with what we do see
3) Can you try connecting another monitor to see if my first guess is correct?

Display works for sure. The whole problem appeared today after I cleaned the gpu (inside as well).
Cpu: AMD fx 8150 3.6Ghz
Motherboard: Asus m5a78l-m
RAM :2x4Gb hyper (1666mhz)
Psu: ocz 650w
HDD: samsung 1Tb (don't remember what exactly but it works 100%)
Gpu: gigabyte Radeon HD 6870

2) Can do it once I get home

3)Yes I have tried it, display is fine, same color crash for another monitor.

It's something with Gpu, because after I unplugged it and booted PC with integrated graphics it worked normally, fully booted in normal mode and worked as always, with normal colors.
The picture I linked is windows loading user account in safe mode (boots up only in safe mode when on GPU). Weird thing is, the display is connected to the gpu, but PC doesn't see gpu, HWmonitor doesn't show it and drivers don't recognize any Gpu as well.
I would be 100% sure it is mechanical error, but I had to reset motherboard after cleaning gpu bcuz of chassis problem,so bios options reseted and therefore there is a chance gpu software crashed and I need to flash it. To sum it up, it only loads safe mode and colors are broken, only low resolution works. What do you think?

Edit: forgot to mention, when I make print screen it is black and white, most of it is black and there is hardly anything visible.

I'm still here, I've just never seen this kind of behavior before. Your answer to my question 3, that it looks exactly the same if you switch to another monitor, does strongly implicate the graphics card.

Which output from the graphics card are you using? Do you get the same distortion if you switch to a totally different output type (DVI / HDMI / DisplayPort)?

 

[AlexKub]

Yes, one monitor was plugged via HDMI and the second one via DVI if I'm right (surely 2 different tho).
I'm 99.9% sure it's gpu by now, the only question I have and can't find answer to is: is it possible that GPUs bios crashed because of motherboards bios reset to default values and that this software issue causes gpu to not work properly?

That initial display looks like a GPU that's been severely overclocked and has failed. You say you cleaned the GPU. What, specifically did you do to clean it? If you removed the heat sink and didn't reinstall it properly it's likely overheating now.

 

[WyomingKnott]

Duh. I've gotten some pretty interesting distortions from an overheated graphics card in the past. Slipped my mind.

Ye I did remove a heat sink and there is a slight chance I messed up reinstalling it, but there is very little to mess up, I put new thermal paste and that would be it basically. Plus could it overheat in 15 seconds? PC was cold as I was cleaning the whole PC, I tried to boot up and it just reseted after 15 secs, fans were working so it shouldn't overheat so quickly even with heat sink being wrongly installed. I wasn't as careful as I should have been with it, the method of cleaning was pretty much "home method". I blew air from my mouth and cleaned it carefully with a tissue in places looking like 95% safe to do it. The only problem I had was removing old thermal paste, it was everywhere, like someone would just put 2 times too much of it, spread it as quickly as possible and installed heat sink all in like 2 minutes. So everything was a mess there. It's probable I could mess sth up while cleaning around the gpu processor.

If the heat sink is not properly seated it most certainly can overheat in a matter of seconds. Once again, remove the heat sink, clean off ALL thermal compound using either isopropol (preferred) or rubbing alcohol. Do not use a paper towel for this. Reapply a small amount of thermal compound and replace the heat sink, making sure that it seats square to the surface of the chip. Once seated, twist it back and forth a couple of times while pushing down on it to spread out the compound. Do not lift the heatsink to check your work or you will have to start from scratch.

 

[AlexKub]

Well then yes I may have made it not good enough. After I removed the heatsink after several unsuccessful trials of booting up, the thermal paste was not spread out as it probably should be, there weren't many traces to be honest. So yeah I'm a retard and managed to mess it up. The screws are used and it's hard to tighten it properly.
I will try to reseat it in 2h, but I guess it is very much possible it got permanently damaged by now because of my mistake, isn't it?
