Pc switches from graphics card to onboard graphics

[Hedzert]

So when i start gaming my pc restarts to the onboard graphics.

My specs are : msi gtx 750ti, msi z97 pc mate, i5 4460, cooler master g650m, 8gb kingston hyper x fury 1600mhz.

My pc will just lose signql from my graphics card, when i then plug the vga connector into my motherboard, i get to see windows booting up, with in device intel hd graphics 4600 as graphics solution.

Have you tried unplugging everything to do with the card and plugging it back in? Have you Checked the temperatures that the card is running at using speedfan or a similar program?

[Hedzert]

@Jambls,

Yes I have, temps dont exceed 70 for gpu and 55 for cpu (Celsius).

I have switched my card to a othed pci slot, problem remains.

[Jambls]

have you cheched the power plugs or is it one of the 750tid that doesn't need it?

[Hedzert]

@Jambls,

Does not need additional PCI-E power

[Jambls]

Have you tested the card in someone elses computer and tested another card in your computer?

[Hedzert]

I ran this card in my older computer that doesnt have integrated graphics without problem.

I also ran heaven benchmark 4.0 on my comouter, it rebooted to integrated graphics again, i then ran it on integrated graphics without* crashes. @Jambls

[Hedzert]

I looked at event viewer and the source is kernel power, the only crash it shows.

[Jambls]

If the card was fine in your old rig test another card in this one. also test the 750ti in another computer to see if it is broken now

@Jambls,

I ran an older graphics card in the sustem and everything is fine, im now putting the 750ti back in the older pc to benchmark

[Hedzert]

I just benchmarked in the old pc with the 750ti, no problems.

So I'm geussing it is the onboard graphics that is the real problem.

[Jambls]

Have you tried using a different psu? I know this sounds strange but the 750ti will be pulling as much power from the board as possible. If you try using a higher wattage

psu, it could power the card better.

If all else fails, rma your motherboard and see if that fixes it

[Hedzert]

Well, my psu is rated at 650 watts, its overpowered for this system.

In the other system i ran the card in has a 350 watt psu. @Jambls

RMA your motherboard.

It is entirely possible that the motherboard cannot provide enough power to run the GPU but it makes no sense that it suddenly broke although this theory fits with it only doing it in games
