I recently installed a Jaton px8400gs_lx video card in a friend's computer (gateway 5620, vista home premium) as a cheap solution when his on-board graphics quit functioning. It worked fine for a short time and then the monitor would go black for a few seconds randomly and then resume working. He never mentioned this and now it has quit working altogether. Upon start-up everything will load just fine until it gets to the log-in screen at which point it immediately goes black and will not come back on. Windows will start fine in safe mode and allow me to log-in, surf internet, etc. but will not bring up login screen if started normally. I reinstalled the nvidia driver for the card and disabled all start-up processes in msconfig hoping to eventually find one that was causing the problem but neither of these fixes worked. I do not know if the card is bad but if it is it can be easily replaced. any help or suggestions appreciated. I hope I posted this in the most correct forum as it seems hardware related, apologies if not. Thanks

You may want to check the power supply requirements of the video card, and also check the wattage of the power supply itself to make sure you've got enough to handle the video card. An over-taxed power supply can cause all kinds of problems.

Also it could be overheating.

ALL Nvidia 8400 and 8600 video processors are BAD. Reference the class action and Nvidia response. This seems to be a classic symptom for desktops and laptop GPU's in this line. This is well known since 2008.
See this enquirer article with exhaustive explanation as to what happened and the fallout from it.

This is not a true statement, i have seen many solid performing 8400 and 8600 video cards. Making blanket statements like that, isn't well informed, nor is it helping with the problem at hand.

I would look at the power supply as well, most OEM computers come with low end PSUs that cannot handle cards of that nature, that would cause overheating, random shut downs, and ultimately, the PSU frying and possibly taking other components with it.

guitargod3195, do you have a spare power supply that you can use to test out?
