New PC, and GPU giving me serious problems.

[Immamonsta]

I just bought a HP Pavilion yesterday which has an I3 processor, 6 GB of RAM, Windows 10. I bought a Geforce GTX 750 PNY Performance Edition card from Best Buy that I cannot get working properly... I am trying to play WoW with it, and within 5 minutes of playing my PC just shuts down on me... sometimes it happens when I open the game. I went and bought an Evga 600W PSU hoping that it would fix the problem, and of course it didn't. I have been trying to fix this problem for months now, I had the same problem when I was trying to install this card to my old PC which is why I purchased a new one hoping that it was just because my old PC was so outdated yet I am getting the exact same problem.
Please help, im begging you

Well, you tried it in two different PCs, you have had it running on 3 different PSUs by now. The only thing consistent with those is the card, so I think the card is faulty.

It sounds like it may be the card, not the PC. Have you done all the driver updates? Does that particular card require a 4 or 6 pin supplemental power connector?

There are no 4-pins for video cards. And it shouldn't.

My mistake. It shouldn't, but it's best to cover all the bases.

Yeah it sure sounds like a bad video card. Can you still swap it at the store or has it been too long? If not, you will have to RMA with the company.

While modern video cards use 6 and 8 pin connectors for power before PCI-E 4 pin LP4 was very common(some cards also used the smaller floppy type power connector).

Unfortunately even with the best efforts some defective cards still make it into the retail market.

First of all,

With pre built systems.
And depending on if it just relied on the on board graphics solution often fitted to them to keep costs down.
Often only four of the eight 12v E-atx power block in such a case are connected to the motherboard.
leaving the other four required not connected.

If it was the case, then you bought a GTX 750 Card to put into the Pci-e graphics card slot.
And the card is the Ti version of the card it can require the six pin 12v Pci-e power connector direct from your Evga 600w power supply unit.

But also if you fitted the Evga power supply and only connected the four Pins of the 12v E-atx connector again.
It was wrong.

If you fit a Pci-e based card to the card slot, and the motherboard has an Eight pin 12v E-atx power block.
You must connect the other four 12v pins on the block required of the mother board to total eight pins of power.

This is because four of the pins on the 12v E-atx power block are used to drive the cpu for extra power demand.
And the second set of four pins provide about 75 watts of power to the actual Pci-e based card slot of the motherboard used to drive any Pci-e card placed in the slot.

With out all of the eight pins connected the system can be unstable.
I suggest you check that all of the eight pins of the 12v E-atx connector on the motherboard are connected up via the feeds from your power supply unit.

And that if the 750 card you have is a Ti version that you check the card for a 12v six pin Pci-e power block.


In short Eight pins of the 12v E-atx located on the motherboard must be connected via the PSU.
The card if a 750 Ti version Should be check for a Six pin 12v Pci-e power connector and connected direct from the PSU to the card if found.

Result system is stable.
