So I had an old crappy computer for years that I had bought a Radeon 7750 for a year or two ago. I decided to upgrade to a pre-built PC which has a GT710, this still didn't meet my needs so I just recently purchased a GTX 750 ti and it doesn't seem to work. When it's in, the lights and fans are working but it just says no signal on my monitor. So I thought how about I try my old Radeon 7750 on this new PC and that has the same exact problem! So i'm trying to figure out why both of these cards are not working on this new PC.

I have a 350w PSU and no 6 pin connectors so I would think ok that's just got to be the issue but then explain why my Radeon 7750 is having the same problem??

Processor: Intel i5 2400 3.10 Ghz
RAM: 16gb
PSU: 350W Bronze FSP Group
Windows 10 64 Bit

I don't have a normal VGA slot for my onboard graphics or even an HDMI slot, so I'm not able to test it out.
My GT710 does work though I forgot to mention so the PC does function.

It's an ASUS model

I don't understand how you can have an i5-2400 (which has integrated graphics) and not have a display output on your motherboard. But anyways, I guess that doesn't matter since it works with your GT 710.

Download or get handy your GTX 750 Ti display driver. Then use Display Driver Uninstaller (http://www.guru3d.com/files-details/display-driver-uninstaller-download.html) to uninstall any and all (Both AMD and Nvidia) drivers and then put your GTX 750 Ti in and see if it will display. Then install it's driver.

Well it has a 6 pin slot but i've been browsing various forums and people say that they can run a GTX 750 ti without a 6 pin connection.

This may be your problem as it isn't guaranteed to work without the power connector. Which make/model GTX 750 Ti did you purchase? Did it not come with a molex connector?

So the driver thing didn't work but I agree with you about the molex connector so I just ordered one. I never received one with my card, the card is new but it wasn't in it's original packaging and such.

So I was able to get it to work by plugging in the 6 pin connectors, but now a new issue has risen.
It all works great but randomly my monitor will turn off and do the same thing as before, this will happen when i'm even just watching a YouTube video.
Any ideas as to what it could be?
