Omen Obelisk problems

[MrCube_]

The FurMark thing crashes almost instantly

What voltages / temperatures you're seeing under the 'sensor' tab?

[MrCube_]

[krzemien]

Can't see much but it all looks normal to me.

FurMark crashing and the fact that you're not able to play any games is quite suggestive.

If temperatures are normal, your cable to monitor is of a good quality and you do not overclock the card either (you don't, correct?) then my thesis is that it's the graphics card memory that's playing up.

So that's something that you should test.

Is this PC under warranty?

[MrCube_]

I don't overclock and I had this pc for about a week, I had to replace the first one because it wasn't booting up (3 slow beeps and 3 fast beeps)

[krzemien]

Oh dear, that does not bode well then...

I would play a bit more with this, and - if unsuccessful in a short term- would get back to retailer asking for suggestions.

[MrCube_]

Okay! and thanks for helping! now I'll play Minecraft since it is the only game that works xD

Do you know what are those green pixels?

Also, it's getting a lot worse now and the hp support is not responding...

[krzemien]

Just a bit more troubleshooting:

How do you connect your screen (and what its size / resolution)? Did you check / try to move the cable? Did you try another port / cable?

[MrCube_]

Via the graphics card, I moved the cable and tried another one but nothing... Do you know if it's possible to get a refund in Italy?
