No Video output after upgrading to a GTX 660 Ti on a new desktop

post #1 of 5
Thread Starter 
Hey all,

Currently upgrading a friends Acer desktop. Model is a brand new DT.SLXAA.010


i7-3770
Windows 8
Intel B75 Express Chipset
10GB DDR3
Integrated Intel HD Graphics


Adding a gigabyte GTX660ti and also a good 650watt PSU.


The machine boots perfectly with the new PSU and the onboard graphics. Then with the new GTX660 Ti installed I get fans etc, but no video output. The PSU is more than enough for the PC.

Can anyone help me out? I currently have no way to test the card in another maching. Is it probably a faulty card?

make sure PCI-E is selected for graphic input. my be different for you but something similar happened to me.

^Yeah, it sounds like the MB may not be defaulting to the discrete card on its own. I'd check around your BIOS for an option to disable the onboard video or set it to auto.

Since you can boot into windows with the onboard video, does windows detect the 660? Can you install drivers for it?

In order to avoid creating another thread regarding this, I decided to post in this thread hoping to bump it and revive it. I'm also running into a similar issue as the person is here, however with slightly different setups. Firstly, I'm using that same model Acer, DT.SLXAA.010. However, I am using the stock Power Supply (300W), and I'm using a Jaton Geforce 210, which requires a 300W power supply and also only draws 30W worth of power. There is no setting whatsoever in the BIOS to disable onboard or to force the PCI-E for video. Whenever the video card is not plugged into the PCI-E slot, the onboard works fine, the computer boots normally, everything is great. Whenever we power it down and seat the Geforce 210 inside the box, we power it on and then no display from either the onboard or from the 210. Just a quick explanation of the situation, this PC is for business use to have multiple monitors set up, but we want a dedicated GPU to do it, so the card itself doesn't need to be all that powerful. I've tried unplugging the wireless card, media drives, and DVD-ROM to see if maybe it was drawing too much power, but that doesn't seem to be the case. Also, we installed a parallel adapter card inside the PCI-E slot, and the computer booted properly and Windows 8 did pick up the parallel card successfully. The problem has really been an enigma of sorts for us that have put our brains together to try and figure it out. I've heard great things about this forum and came here in hopes of anyone being able to give me some insight as to why this isn't working. Thanks in advance!

Spirit, I ended up getting it to work. After rebooting it 3 times, I got kinda frustrated. I left the thing on for about 5 minutes while googling and checking on here, but it suddenly started working and I have had no problems since. No idea how, I guess it just started working!
