Another (Nearly) Failed Upgrade. This time: PSU
 

Hi.

After getting help from you guys fixing my RAM upgrade, I know have another problem for you to take a crack at.

I decided to upgrade my video card, but anticipating a higher demand for power, I tried to upgrade my PSU to something higher than 350W. I went with a 465W unit (SafePower brand). The upgrade seemed easy enough, except I struggled a bit figuring out the whole 20+4 thing. (I was trying to plug in the +4, when instead I needed to plug in a different 4 peg plug.)

Anyway, now that I got my CPU to powerup finally, me existing AGP video card (Radeon 9550) has stopped working completely. I needed to plug my monitor into the onboard VGA jack to get video to work at all (I'm now looking at 800X600 32-bit). Now I can't even locate the AGP card. When I try to install ATI drivers, it says it cannot even locate the hardware and it won't install anything.

Here's what I don't know how to do (and I know it): the guy who set up my computer did something to disable the onboard graphics (I have a ASUS P4S800-MX mobo). I don't really know how to do this... and it would be a bit of a bother to contact the guy who did this originally (it will be my last resort). I understand there might be a jumper, or perhaps a BIOS setting. Either way, I'm not sure it will matter now anyway because my AGP card seems like it's not even there.

Right now, I've reattached my original PSU and the AGP card still doesn't work.

Your help would be appreciated.

Let me know if I should just bring my CPU and replacement PSU into the computer store where I'll get my new graphics card and just have them do it all, or if it's something simple that I'm overlooking.

Thanks.

sounds like you fried your card by giving the mother board the wrong voltage. did you actually try to power it on when you had the wrong power cable plugged into the mother board?

Yes. Several times.

And this is a thought I had entertained. So that would fry it, would it? Is that extra socket for powering the AGP slot specifically? (i.e. Is it possible I've damaged something in addition to my AGP card, if that's the case?)

If I have fried the card, it's a good thing I had planned on replacing it anyway.

I think this is the last time I try to do things on my own. People like me should pay technicians for a reason... :rolleyes:

same reason i don't do anything but add oil and gas to my car.

Sounds to me like either your AGP slot or your videocard or both are fried. There is no "AGP switch" or jumper that allows AGP support. Try a different AGP card in it if you can..if that works, your card is fried, if it doesn't, it's probably the AGP slot.

BTW even with your onboard video, your resolution should go higher and you technically shouldn't be able to tell a difference. You need to install the onboard video drivers to get the onboard video hardware running.
