Hardware Voltage issue

[Seratonin]

I have been recently using the computer I built and I notice that when I move some windows the windows trail. I called EVGA and they said it could be because of my PSU or my GPU. I told them my voltage readings on my 12v and they said it was too high. My 12 volt goes from 12.288 to 12.416. Here are my voltages.

I have a hx750 watt gold PSU that my friend gave me. He said it was new and it has warranty. I also have a regular GTX 660 from EVGA.

You are not going to get exact +12.00 V even with top of the quality PSU.

The only way to get an accurate reading of voltage is to use multi-meter and tap into yellow and black wire. No software or BIOS can give you an accurate reading. Since you have computer running your +12 V should be within ATX spec.

HX750 is a decent quality PSU. Since you say you build your PC, mind giving us the full specification?

Everything looks fine. Curious why you use 3570K when you have H77 motherboard.

But EVGA support sure is no good. Even if +12.416 V is the accurate reading (which is not), that is still within ATX spec and nowhere near too high. ATX spec calls for +12 V to be ranged from +11.40 V to +12.60 V.

You did connect the extra PCIe power cable to the GPU right?

I accidentally listed a different CPU. I have a Intel i5 2500k. I connected the 6+2 connector to the card and I put the 2 pin aside because the card needs 6 pins. I am still having problems as I see the windows trails on my screen. I didn't connect any other cables if that answers your question.

Just know that you cannot do any overclocking on H77 motherboard with K CPU (you'll need either P67, Z68, or Z77 motherboard).

Have you installed the latest Nvidia driver? Is it stable or beta?

 

[Seratonin]

I haven't been overclocking and I have the beta version of the drivers. Will I need to replace the board?

 

[trumpet-205]

No. It is just that most people get K CPU with overclocking in mind, hence I asked why H77. It is perfectly fine to use it as is without overclocking.

Try the stable version of the driver.

 

[Seratonin]

Do I just uninstall with device manager? Can you recommend me a link to go to for the specific driver. Just in case because I don't want to screw things up.

EDIT - False alarm it works.
