How to know which component died?

[iwanttodie]

Recently I assumed that my videocard died.
After surfing some forums I now have doubts.
How do I know which one died/dying: PCE slot, PSU, or the Video card without being able to test the card in someone’s PC?
Symptoms:
When I boot without the videocard using onboard graphics it starts normally.
If I boot with the videocard in the slot but HDMI is still conected to the motherboard - i see the black screen with the blinking underscore(it doesnt boot windows/bios so maybe there is not enough power to power the HDD?)
If i boot with the video card and the hdmi is in the video card - i get a few artifacts followed by a black permanent screen.
So how do I know which one is it?

There is a good deal on the GTX 1060 6GB right now so I want to be sure that if I buy it it will not go to waste.
Thank you

Hello iwanttodie,

If I boot with the videocard in the slot but HDMI is still conected to the motherboard - i see the black screen with the blinking underscore(it doesnt boot windows/bios

That is normal behaviour as the integrated graphics are disabled by default when an add on video card is detected in the pci-e slot during the power on self test.

If i boot with the video card and the hdmi is in the video card - i get a few artifacts followed by a black permanent screen.

Could be a bad card, a bad pci-e slot on the MB, bad drivers or an under powered PSU.

Please provide information about your computer, this includes is it a custom build or brand name such as Dell or HP, if a brand name, provide the model name or series number (not serial) if a custom build post the brand and model name or number for the MB, the RAM (including the amount) add on video card and the PSU (power supply unit) providing these details will enable us to better assist you.

Thanks for the reply.
Here are the details:

My graphics card is Radeon R9 270X from Club3D.
The pc runs just fine without it, i’ve been using it for over a week now.
PSU is Thermaltake TT-500NL2NK-A. A 500 watt psu.
I fairly constantly update my drivers using the ReLive program, so the driver should not be the problem I believe.
Thanks again!

Update.
Went to CanadaComputers and asked them to test the videocard.
They said it would be 20$ and would take several days(He gave some lame excuse). I walked out and will never step my foot in there again.
Found out that I actually have an NCIX store near me!
Went there.
Asked the guy to plug in the card if he can, the guy took it with no charge and just plugged in in the pc they had in the back(literally took 1 minute). I saw the same artifacts as on my pc, so the solution is clear: Dead card.
Then the sales guy walked me through some choices they had for my budget and I ended up at the 1060 again.
Thanks phillpower2 for the help!
