• I put a graphics card in with a PSU that was too weak.

After reading on the internet that it would be OK to do so, I put in my new graphics card with a PSU that wasn't rated for enough power to run the card. Big mistake. The computer started up for 10 seconds then shut down. After that it would not start at all. I put in my old graphics card and it starts up fine, so it seems clear that the new graphics card is toast. What I'm wondering is if it's possible to have it repaired or if it's gone forever. So is it worth bothering to get it looked at by a professional? [editline]cock o' clock[/editline] I got a new PSU with plenty of power, and the computer still doesn't start with the new card in it, but works like normal with the old card
Uhh i don't think that a psu weaker than the minimal psu power of the graphics card can toast..
It's not likely that it's broken the graphics card, but I suppose it could happen - the only way to find out easily is to get a new good quality PSU that will cut the mustard, and even if the card is broken, you have much more upgrade potential with a new one.
all that means is "WE AINT GETTING ENOUGH POWER GET LOST" *turns off* Go buy your self a better PSU should fix the problem
Why would this lead you to the conclusion your new card is fried? What other electronics do you know that run without the adaquate power needed to run them?
some actually useful information would be nice, say for example what PSU and graphics card and if a card doesn't have enough power it makes a high pitched squealing noise
I doubt the gpu is dead. :phoneb::phone:
Is the PSU stock?
Okay. The original setup was a nVidia 7900 GT with a 400 watt rated PSU. I put in a nVidia 8800 GT with the same power supply and the computer shut down shortly. I knew from reading the requirements of the gpu that the PSU wasn't powerful enough. I believe the card requires a PSU of about 500 watts. Then, thinking that it just wouldn't start because it didn't have enough power, I got a 750 watt power supply because it would easily fill all my PSU needs. I put in the PSU and left in the old 7900. Starts up like normal. Swap it out for the 8800, and despite plenty of power, it does nothing when I try to power the computer on. The new PSU is the 750TX from Corsair, I'm getting the impression that this brand is reliable, so I think a mediocre-quality PSU isn't the problem. [editline]11:00PM[/editline] Some extra info: I messed with my computer a little and found that if I turn the power supply switch off and leave it for a few seconds, then turn it to the on position, the computer's "on" light will instantly flash and make a quiet high pitched beep sort of sound. This is with the 8800 installed and the new power supply. It still doesn't power on
Man, that would suck if your 8800 got toasted, better get it looked at by a professional and maybe it can be salvaged.

It shouldnt be broken, I bet you just got a faulty card.
[QUOTE=nikerocks123;19221415]There isn't an 8800 GT on that chart...[/QUOTE] and? if 500W can run a 295, I think [I]somehow[/I] it might [I]just about[/I] manage an 8800. just because a chart doesn't hold your hand and point out the answer for you doesn't mean it's irrelevant

The card's not broken. There is just to much load on the small amount of wattage your power supply is dishing out. A 600W power supply can be purchased for $80 so I recommend upgrading.
