PC does not shut off
 
Greetings fellow tech junkies, I thought I'd throw a little issue I'm having out there for you all to mull over.

I received a new video card for Christmas this year. It's an ASUS Nvidia GTS450, and I installed it in my PC. For about a week I had no issues and then my PC started to not shut off when I tell it to shut down. Windows shuts down, the display goes blank, but the case fans, and pwr. supply fan remain on and have to be shut off using the power button. I have absolutely zero issues when the machine is on. I did not have this issue with the previous graphics card (a BFG Tech Nvidia 8800GT) So my thoughts are that it is possibly driver related or some hardware incompatibility or something along those lines, but I thought I'd get some other opinions.

OS: Windows 7 x64

Motherboard: MSI P6N Diamond

Graphics card: ASUS Nvidia GTS450

RAM: 4GB DDR2

Processor: Intel Core 2 Duo@2.13GHZ

Power Supply: Thermaltake 650W

got the newest bios for your mobo?

the card may be drawing current or something causing the power supply to not shut down, possibly a defect. Never heard of anyone with this particular problem before, but I doubt it driver related.

Small update...I shut the machine off to go to work earlier and when I tried to turn it on again I got fans, light on disc drive, but no display and no power to peripherals...(usb keyboard and mouse). I didn't have time to throw my old card back in the case and see if that resolved the problem...

I wonder if the card is fully seated in the slot?

If so, it sounds like a short may have occurred either in the MoBo or 450, hopefully the 450. I would return/exchange the card (assuming you have time left) and install the replacement, see if the behavior persists. You have more than enough power for the card, assuming your MoBo driver is up to date as acdcfanbill asks, it has to be a hardware issue.

What does your event log have to say about things?

Q 01-15-2011 07:36 AM

Did you reinstall the video drivers when you switched to the new video card? Yes, I know that they're the same brand of card and will use the same driver package, but your new card is of a completely new generation and the drivers configure themselves to the new hardware as they're installed.

I would recommend this as well, only be sure to flash it through the BIOS from either a floppy or USB drive.

DON'T USE ANY TYPE OF WINDOWS-BASED FLASHING UTILITY, BECAUSE IT CAN BRICK YOUR MOTHERBOARD, AND YOU'LL BE REALLY, REALLY SCREWED.

JediAthos 01-15-2011 09:23 AM

thanks folks...I'll take a look at the mobo BIOS and what not when I get back to the computer Sunday evening though it looks like MSI hasn't released a new BIOS for my mobo since 2007. I was thinking hardware myself given I wasn't having a problem until I installed the new card...

@evil Q: yup I installed the drivers from the CD included with the card.

my wife bought the card from newegg and its beyond the 30 days on their return policy, but I'm going to call ASUS as I think I should still be able to get warranty service from them.

Char Ell 01-15-2011 09:59 AM

Hmmm... Interesting that you didn't get any power to your peripheral devices. If it was just the vid card going bad I would've expected your peripherals to be unaffected.

On somewhat related note, back in the day I had a MSI P4N Diamond and it would never power down on it's own. It would shut down Windows XP but would never actually shut off the power. I always had to manually hold the power button to power off or hit the reset button if all I wanted to do was reboot.

Awkward. Weird.

Well...got back to the computer tonight...turned it on, and nothing. Case fans start, mobo fans start, pwr. supply fan running, pwr to fan on graphics card, but no display. Put my old card back in...same symptoms..uh oh...hoping against hope I threw a power supply at the problem...same symptoms.

Sadly it seems as though my mobo may be toast. I tried a different PCI-E slot to no avail. *sigh*

Q 01-17-2011 08:50 AM

Yeah, that's definitely what it sounds like to me. :(

Decent Socket 775 motherboards are becoming increasingly rare; especially 680i/780i boards like the one that just died on you. The only ones that are plentiful are the cheap G41 models for ~$60. They don't have many features, but they're not bad, and one of those would be the simplest and cheapest solution to your problem. You'd have to reinstall Windows, of course. Is your memory 2x2GB or 4x1?

JediAthos 01-17-2011 04:06 PM

I had forgotten that I had an old Intel 775 motherboard laying around. I put it in this afternoon and fired it up and sure enough it started. I"m in the process of reinstalling Win 7 and I've done so using my old 8800Gt Video Card. I'm not sure I'll try using the new GTS 450 and might just see if ASUS will take it back.

Thoughts?

Q 01-17-2011 04:40 PM

Why not? It doesn't really sound like the new video card had anything to do with your mobo dying.

JediAthos 01-18-2011 02:15 PM

Is there anyway I can be sure that the new card didn't somehow affect the mobo? This is the first time I've ever come across an issue like this.

Q 01-18-2011 06:38 PM

I can't be sure of anything, but the fact that your motherboard died a week after you installed the new card instead of right away tells me that it's likely that it was just its time to die, and that you should be able to safely use the new card with the other motherboard.

Incidentally, though that GTS 450 is quite a bit more powerful than the 8800GT, it actually draws about 19 fewer watts at load.

JediAthos 01-18-2011 07:26 PM

I'm thinkin I'll give it a try...maybe not tonight because I'll have to rearrange the case a bit due to the size of the card, and the proximity of the PCI-E slot on the mobo to my hard drive.

*Update* Up on the new card as of about an hour ago. I spoke with ASUS tech support and they said there is no reason it shouldn't work in a PCI-E x16 slot as PCI-E 2.0 is backward compatible. So far so good...

PC does not shut off
 
1. If the computer is frozen, to turn off the computer, hold down the power button without letting go for 10 - 15 seconds.
2. If your computer is a laptop and doing the above still does not turn off the computer, unplug the computer and remove the battery.
