Lightning cripples my pc!!

May 25, 2011 at 02:27:15
Specs: Windows 7, 2200/2048
I have a Compaq Presario sr1750nx with a Asus A8AE-LE mainboard.
I got hit with lightning last Thursday night - I got it up running after putting in a new power supply and removing all pci cards as the pc would not start with cards installed and I am only getting audio of out my left speaker other than that no other problems.

Does anybody know of where locally (Oklahoma City) I can possibly buy a new or fully working used mainboard of this model?

Or can possibly fix the mainboard I have?

The fact that it works with the PCI cards out but doesn't with the PCI cards in suggests to me that it is the PCI cards that are at fault, not the motherboard.

Although it still could stll be the motherboard I would first try a couple of new PCI cards first of the type that you removed. They are not expensive and may save you the expense of a new motherboard.

If the audio is built into the motherboard, a PCI Audi card should solve that problem.

The only other pci card I have that wasn't in the pc at the time is an old modem card and I put it in and windows detected it as a "pci comminications device" but could not find the drivers for it and I don't have the drivers.
I tried the modem card again that was in there and the pc would not start so I took it back out and the pc started so I put my tv tuner card back in and windows started and it installed a driver that I didn't recognize and I had like 4 other entries in device manager that said "unidentified device" and " multimedia device" with exclamation points. So I downloaded the drivers off the manufactures website and had to force install and it showed to be installed but I still had 2 "multimedia device" entries with the exclamation points. So tv tuner card did not work. I'm going to install my tv tuner card in my friends pc to see if it installs without problems and if it does I will know for sure its my pc but if it doesn't then its the card. I might try the same with the modem card as well but I'm thinking that it is dead for sure since my pc would not even get to the bios post.

I just wish the audio in my right speaker would work but if nothing is wrong with the pci slots then I can live with installing a pci audio card but if there is something wrong with my pci slots then I will have to go with a usb audio card for the time being.

Don't know if my onboard ethernet works don't have anything to plug into to check.
Also I have 1394 firewire ports don't know if that works either cause I don't have anything that uses firewire. My usb works fine and as far as I can tell everything else is working perfect other than right audio channel not working and maybe pci.

You have addressed most of your issues. You can download a utility called SIW that may help you identify your hardware so you know where to get drivers.

The sound may be damaged or you may have a damaged speaker. Try switching the L&R speakers to see what happens.

TV tuner cards can be temperamental to install right. Best to have all the files available and also installation instructions. The two entries that have exclamation points may be the sound. You probably need to remove all the drivers and entries in Device manager for the tuner and start over fresh.

Get SIW free version at the link below.

Thanks for the reply!
I tried headphones and the speakers in both rear and front jacks of my pc so I know its my onboard sound.
The entries that had exclamation points do not show up if my tv tuner card is not in the pc.
I know the drivers worked fine with the tv tuner card prior to being power spiked.
When I first installed Windows 7 on my pc it downloaded and installed the right drivers for my tv tuner card and it worked fine infact I did not even have to install any drivers as Windows took care of all of it for me. But like I said earlier I did download and install the drivers off the manufacture's website but I had to force install unlike before when it installed by itself but still errors showed up and card would not work so I removed it so I have nothing in my pci slots right now and no errors in device manager.

Well, the lightning may have damaged the TV tuner card and the sound too. The TV tuner card needs to use the sound device for the audio portion of the signal. So drivers are installed for sound capture. That is what is not installed, which may make sense if the sound chip is fried.

As Stuart stated, you can install a sound card. If you don't use networking or Fire wire 1394 then who cares if they work or not.

Do you use a dial up connection for internet?

I'm using a usb wireless networking to connect to a router then to the internet and I'm glad I'm using that instead of using a wireless pci card or that may be fried as well!

Like I said earlier I'm going to put my tv tuner card in my friends pc and see what happens before I junk my tv tuner card without knowing for sure as I paid over $100 for this card a coupe of years ago. And also that will prove to me as to the status of my pci slots whether they are working or not.

True on the ethernet and firewire but just in case I do need them I want to know that they are working but at this point I'm going to assume they are.

The TV tuner card may be obsolete in short order anyway because Analog is going away. Did you try a different PCI slot for the TV card?

Was the computer turned on at the time of the lightning strike?

I live in Oklahoma!
My tv tuner card supports the digital and analog signal it is a Pinnacle PCTV HD TV Tuner Card (800i).

I tried another pci slot and still the same problems.

Unfortunatly yes I was on the pc when lightning hit -- Yes I know I learned my lesson! lol!! Turn my pc off when the sound of thunder is coming or flashes of light are showing!

I went and installed the tv tuner card in his pc and I got the same problems as like on mine so I assume the tv tuner card is bad!

But he gave me a pci audio card that he had in a very old pc of his and that works. So I know my pci slots work. So the modem card and tv tuner card is bad.

So now I will be looking for a another tv tuner card to buy -- any ideas on a good cheap one?

OKC, I remember it well. Listening to Ronnie Kaye on WKY radio in the afternoon and Jim 'Gooseberry' Bowman and his alter ego, Rat Fenque, in the evening. I wonder what they're doing now. Edit (Part of Dave's rambling about his lost teen years have been edited to protect the innocent). . . Padre Island during spring break. I wonder what she's doing now! OU, My '66 mustang. . .

And here I am now, sitting in front of a computer getting old and fat. Sigh

Well anyway, if you're looking for old hardware you're pretty much stuck with ebay. That old stuff is too inexpensive for a shop to stay in business selling it. You'll find a lot of computers at garage sales and thrift stores but if you want a particular item then it's gotta be ebay.

Ding dong the witch is dead. . . .

I looked on ebay and seen a few motherboards of my model on there.
But as it goes I may not need it. The only thing I can see wrong is my onboard audio is messed up but I'm using a pci audio card so no need for the onboard and I got rid of the tuner card and modem card as they were fried.
