Graphics Card Fan is Working but No Signal to Monitor! Please help me!

[Player]

I've recently bought a new graphics card a week ago and have only used it a couple of day because of school. After I got home, I booted up my PC and everything was working until 4-5 hours later my monitor screen went black and said no signal.

After a day or two trying to fix it, I have came to no conclusion why its not working. It only works when my graphics card isn't plugged in. Note- my graphics card isn't broken or anything because it is pretty much brand new. And, only sometimes it works... but only for about 10 minutes or so then screen says no signal.

I have tried uninstalling drivers and installing them again and it still doesn't work. My graphics card is a Nvidia GTX650 2GB. It doesn't have a 4-pin or a 6-pin connector because it pulls 74w straight out of the mother board from the power supply. Please help me.

I'd say it is unusual thay your motherboard drivers wouldn't be up to date enough to support the card but as a rule of thumb if you change gpu you should always make sure the BIOS version of your motherboard is up to date. To do this check the make and model and download the latest BIOS version. There is usual a flash facility when entering the BIOS when booting the pc.

Also try resetting the CMOS. Depending on the model this means taking the round battery out of its slot on the mobo or there could be a jumper you can find how to so this in the manual/online.

Next shout is the display, if you have more than one monitor test another or with a TV. If you have access to other connection types you could try connecting it via DVI or HDMI or whatever connection you haven't tried and see if that helps at all.

Of course there is always the occasional "I got it to work by taking it out and re seating it" and as a pc builder I cannot stress the importance of this as it is a common mistake even for the pros ;).

You say there are no connectors and I have seen 650s without them but does your power supply have the wattage for this card? 400W should be a minimum for this card I believe.

For now that's all I can think of but it is a few things to try to try and resolve a mo signal issue.

Of course there could be more to it. If the card has periods where it does work then it could be a heat issue causing it to turn off before it burns out bur with a working fan this could mean the unit is not working correctly

You need to try another Power Supply.

Then if u can get as far as Windows, monitor the Temps for CPU/GPU and ensure it's not just overheating and then the display might cut out, system reboots, or the system just hard-locks.

Doesn't matter if the GPU is new, it sure as hell can be the GPU just as much as anything else.

Once in Windows, uninstall GPU Drivers and then reboot when asked, then do a clean GPU Driver install. If you don't understand "Clean Driver Install" ask.

I had a similar issue once. Fought with it all thru the night... got very angry trying to find a solution... and it ended up being a faulty hdmi cable. Go figure. Might want to try a different cable.

I have tried 3 different cables plus tried them on my brothers pc and they all work fine.
