Question about Ultra Products Ultra LS500 Lifetime Series 500W Power Supply - ATX, SATA-Ready, PCI-Express 500-Watt Power Supply

1 Answer

Power Supply and Video keep going out.

I have an ASUS M3N78 Pro Motherboard with a Sparkle NVidia GeForce 9400 GT Video Card and an Ultra LS500 Power Supply. All were working fine for about 3 weeks then one morning I had no power. I plugged the PC into a different outlet and the power supply was working again so I brought it back into the office and plugged everything back in but now there is no signal to the monitor. Tried all connections and a different monitor, still no signal. Then after running for about 15 minutes the power supply shut off again and PC won't boot. I'm not sure if the power supply is faulty or there's a conflict with the video card or both. Any ideas?

I would suggest that you try and check the system with another power pack, just to be sure that it is not the power supply that is faulty.
This is because what you have describe here is one of the symptoms of a failing power supply, and It is not always advisable to take a power supply case lightly, and when it is detected that its the one that is faulty, Just change the power pack OUTRIGHT! and please don't think of repairing it. It is not always expensive though, as compared to if your whole system now starts to develop fault because of it.
Hope this helps you out.
Goodluck.

My geforce 9400 GT will not properly install drivers in my ASUS M2V-MX SE. When install the nvidia drivers old and new. the video card has a yellow exclamation next to it


If you uninstall the onboard driver and then update the new cards driver in device manager the problem should be solved.

If not you can always reinstall your operating system, that usually solves any driver issue.

If that doesn't work then your card is most likely not compatible with your motherboard.

256 MB Nvidia GeForce Go 7800 for Inspiron 9400/E1705 Card Failu


Both solutions are wrong. The Dell Inspiron 9400/1705 is a laptop. If you buy a Nvidia GeForce Go 7800 for this laptop, you need to buy a Dell Inspiron 9400/E1705 motherboard for a discrete video card. The integrated video is a Intel Graphics Media Accelerator 950. The integrated video has the video chipset on the motherboard and the discrete video (GeForce Go 7800) has the video chipset on the video card.
