I was testing a new video card in my computer and got this message during system start-up:
"Alert! Previous Voltage Failure"
The card worked fine for me so I'm not sure why this message appeared.
My computer is a Dell 530 Precession, running Windows XP,
The new card is a BFG 7800 GS OC 256MB 8X AGP.
My motherboard only support 4X AGP. When I put my old 4X AGP card in this message disappears. Could this be the cause for this alert message?
I don't think so. The AGP cards are backwards compatible so you can use a 8X in a 4X slot. It seems more likely the PSU is not giving the card the voltage required. I am presuming you have the original PSU in you machine. It might be adequate for everything Dell put in there, but not for a bigger (More powerful) card
Try reading a few links on this page
As a for instance the PSU selector takes you to this Page (I figure you to be dyslexic like me, so your 530 is really a 350?)
Did you plug a 4 pin molex power connector into the end of the video card?
Dell has an alert like that when the system voltage gets out of tolerance . The new card was probably the cause , but you should look into the possibility your psu is getting weak or failing. Use a voltmeter to check the voltage on all the rails 3.3v (orange), 5v (red), 12v (yellow) . They should be within +/- 10% and steady within .02, preferably less . Check at idle and under load.
That's the same thing I said. :)Quote:
