Ghetto build gpu issue

DayneD89 · October 2, 2018

So I'm going to have to quickly introduce myself to explain this build, so I'm a single dad on a budget of essentially £0. This shows in the build specs as it's all scavenger parts. No, I do not expect to get much out of it. My main hope is to play fallout 3 as I'm a big fallout fan. As it's all used none can really be relied upon and anything could be faulty. Still, here's what I had built and working:

Core 2 quad q8200

2x2gb ddr2 ram

450w psu

500gb hdd

With some minimal ubuntu 64bit over vista that had been on the drive and it booted fine with onboard graphics (nvidia prop. driver).

Next step gpu, and here I have a gtx 465. That could probably do with more power though and whoever had that before me had chopped the pcie power cable off anyway. So after a search I find a 650w psu with 2 pcie 6+2 connectors on one cable.

With the new gpu and psu installed I get the bios and it posts perfectly fine. Past that I get enough white lines over the screen to make it unusable. If I go into the bios settings things are fine, after that I get the same thing. Watching the login carefully I can see that a bash login shows briefly but as soon as the GUI login (iirc its MATE I ended up putting on) the screen goes black. After a while power cuts off.

With power taken out of the gtx 465 but the card left over and cables moved over to onboard, it works as it did before, though power did cut out suddenly at one point. That hasn't happened since I pulled the card out completely though.

What would you do to diagnose the gpu in this state? I have a cd drive, however only one mobo sata port is available with the gtx in, going to my hdd. I have no flash media other that some sd cards with raspbien lite on, but no sd card reader and I doubt the bios boots from USB anyway.

You might have two issues:

(1) The existing driver is looking for another video card (the onboard one) and going stupid when it finds the GTX 465.

or

(2) the GTX 465 is bad...

Probably the latter tbh, but I won't know for sure unless I can find a gpu I know works to test in it I guess. I did install vanilla ubuntu and tried running that with the 465 installed on first boot but have the same issue, so it is the most likely. Unfortunately I can't do a proper install with the 465 in as it blocks all but one data port, needed for the had and this disabling the cd drive which is the only other bootable device I have
