Title: Can a gfx card be damaged this way?
Post by: moot on December 09, 2008, 06:07:39 AM
The motherboard started flakin out a month back: my PCIe Geforce 9800 stopped being recognized even in Device Manager, even when I told the bios to use PCIe as primary display driver.

Is there a chance it hurt the gfx card if I left it plugged in as normal while I ran the PC on and off for a few weeks? I've had to get some work done while running the PC on the onboard gfx chipset, then left it on for about two hours at a time once or twice a week to recharge an ipod when the PC stopped booting windows altogether (it gave the Dos "HARD DISK OR BOOT DISK ERROR"), and now after about three weeks of it being off because it wouldnt even post, Ive managed to restart the PC using an old HDD and took the opportunity to get some work done with the basic stuff (no video and sound drivers, just enough to run MS-Office etc). It still doesnt see the graphics card in the device manager.  The card sounds normal, does the same routine (fan spin-up on boot and shut down) as it normaly would..

DxDiag might help. Which version of Windows does this new HD have that you're currently using?

What size power supply are you using?

All hard drives are XP, this present one (havent dared turn it off since it booted) is SP2.
Power supply is a 700 watt Rocketfish.. should be rated a few amps above reqs of the card..  Ugh.. Now that I actualy check, it looks like the PS is rated 18 amps max, whereas the card requires 24 minimum.. That salesman's gonna have a visit tomorrow.

I guess that's it then... But did this damage the card?  It ran fine for about two weeks.

I guess it could damage the card. Here's what you do:

Go to the store, buy a PSU that matches your required specs.
Go home, try it.
If it works, problem solved.
If it doesn't, put it back in the box and return the PSU.

Matt, grab it while it is dirt cheap.   A few of us have the 750w version, but this is cheap, quality and stout.

Alright, something didnt add up.. The salesman would get fired for saying yes twice when I asked specificaly if the video card would work on this PS (bought both at same store).. And it's a medium-high priced PS with good quality build, so it ought to work with this vid card..

This is the PS specs:
DC+12V1+12V2+12V3+5V+3.3V-12V+5VSB
Amps18A18A16A28A30A0.8A3A
Power492W" "" "140W" "9.6W15W

Is the actual 12V rating the sum of more than one 12V rating?  The card has two 12V connected.

Yes.   It just spreads the 12v's to more than one "rail".

Sorry, I mean do you add up the amperage from those two 12V lines?

Yes but the question is, what else is connected to those same 12V rails?

They're on separate sockets on the PS box. Lemme get a pic..

20+4 is on the motherboard, EPS12V is near the CPU, there's 3 drives on 5.25" format molexes, nothing on SATA, nothing on FDD, and the two and only dedicated PCIE 6-pin 12V's are on the card.

You should have plenty of @'s on your 12v rail. Your showing 492W which = 41 @mps. Most cards will allow a single rail to draw as needed against the total amps. It is possible that this PS might cap an individual rail at 18@'s however...

Ok.. So assuming that it did under-current the card, would that damage it?

yes

Finally found some good info on this damn PSU.  See the last post here:
http://www.hardforum.com/showthread.php?t=1195127

And just to be sure I understood.. Having two 12V rails at 18amps means the card should get ~36 amps, right?

99% of the time yes...

Check with your motherboard.  Beep codes vary by vendor.

Yeah it's a graphics error.. Graphics memory or graphics something, I forget.  The damn user manual doesnt even have a table for beep codes. Unbelievable.
I'm totaly fed up with computer glitches..

edit- this is on a replacement motherboard I got today.  Asus M2N SLI. It doesnt even do the pre-recorded error voice messages.

Removed it from the new motherboard today (figured i'd let it all sit off-power for a while and try turning it on one last time), and the monitor came out of standby to display 'no signal'. Would this mean that only a component on the card failed? If so, how hard would it be to replace it?
