Computer will not turn on if GFX card is plugged in. But when unplugged it boots up just fine.

Basicly what the title a says. My computer will turn on for a split second then power off but as sson as i takr out my fx 7950 it works. I swapped my 7950 out for a gt 630m and it boots fine. I have no clue whats wrong.

turkey3_scratch · Oct 8, 2015

What are your full specs?

laviniuc · Oct 8, 2015

psu model and wattage please... sounds like the psu can't power the 7950, with the 630 it works because it can run on hamster power.

edit: look also for a bios update for your motherboard

Mobo: gigabyte z97x-SLI
graphics card: R 7950
Psu: Antec 620 w
Processor: i7 4790kat 4.3 ghz
Ram : stock dell ram 10gb
Cooler: H100i with 2 fand on the rad and 3 on the front of my case
Hdd: 1tb 7200 rpm

But the thing is my computer was running fine for close to 8 months when one day i was rendering a video it just powered off and hasnt powered back on

laviniuc · Oct 8, 2015

it's possible that the graphics card is damaged too.. you have any friends with a 600w psu pc where you can test it?

laviniuc · Oct 8, 2015

the psu is enough, and antec makes good psu-s so should be fine... did you plug the pci ex power cables back into the card after you replaced it with the 630?

turkey3_scratch · Oct 8, 2015

Did you just buy this card from Ebay? Are the power cables attatched, too?

Bl4ckout · Oct 8, 2015

@laviniuc yeah i made sure to do that, ive aslo take my motherboard out to make sure nothings shorting it out. Im going to check now if my mobo has a bios update.

Bl4ckout · Oct 8, 2015

No i bought this card from newegg like 5 years ago so its a pretty old i wouldn't be too surprised if it just died

Bl4ckout · Oct 8, 2015

Yeah i do have friends to test this but none are able to come over now to do so. I plan on testing with another psu in the future.

Bl4ckout · Oct 8, 2015

There is a BIOS update im downloading right now, wish me luck.

turkey3_scratch · Oct 8, 2015

I am 99.9999% sure it has nothing to do with a BIOS issue.

Bl4ckout · Oct 8, 2015

@turkey3_scratch what do you think it is then?

turkey3_scratch · Oct 8, 2015

I honestly have no clue, but there is no reason the card would not be able to run without a BIOS update.

Bl4ckout · Oct 8, 2015

Could it have just died?

turkey3_scratch · Oct 8, 2015

You say the card is 5 years old. Did it used to work in this motherboard in the past?

Bl4ckout · Oct 8, 2015

turkey3_scratch :

Yes, It worked for about 4-5 months

turkey3_scratch · Oct 8, 2015

Bl4ckout :

Then all of a sudden your computer did not work, but switching cards makes it work, correct?

Bl4ckout · Oct 8, 2015

turkey3_scratch :

Yes, I swapped my old Grapics card out for a new one and it boots up. Would a system power on then power back off like that if the older Grapics card is dead?

turkey3_scratch · Oct 8, 2015

It might. Considering that swapping graphics card fixes the problem, it could very well be just a dead card.

Bl4ckout · Oct 8, 2015

@turkey3_scratch
Alright, well thanks for the help anyway. While your here though do you have any recommendations for a Grapics card? I normally play Csgo and looking to play the new Fallout when it comes out. Any suggestions?

turkey3_scratch · Oct 8, 2015

If you have a 1080p monitor I'd get a GTX 970.

Bl4ckout · Oct 8, 2015

Yeah thats the one I was looking to get too, hey man thanks alot

turkey3_scratch · Oct 8, 2015

You're welcome!
