Lightning damage to computer - how screwed am I?
Posted on 7/1/15 at 7:47 am
Posted on 7/1/15 at 7:47 am
Lightning hit close by yesterday, zapped cable boxes, one TV and computer.
Computer won't turn on, no fans, nothing, but the "power" LED on the motherboard is blinking (steady ON normally). I'm hoping this is a sign that just my power supply is fried - is this a good assumption?
Help from the h/w guru's here much appreciated. I'm at work so no pic's for your troubles...

Not a h/w guru, but if the LED on the motherboard is blinking, it's probably not the power supply. Is it a steady blink, or a pattern (3 blinks pause 3 blinks etc)? If it's a pattern, you can probably find an error code for the motherboard.

steady blink on/off, about once a second.

You can try the paperclip method to test the power supply independently

See if the supply has a reset, I've seen some on the inside of older models.
One of our 6+ year old T7400's had almost the same thing happen with only the LED's appearing to work and nothing else. I pulled the plug from the power supply, hit the reset button and pushed the power button. Everything was working the way it should (blinking LED's on optical drive, fans blowing normally, etc.) and about 3-5 seconds after hitting the start button we had another surge. Never saw the post screen and the fans were constantly increasing in RPM. Knowing that I'll be replacing it soon I let it go for another 15 seconds until it sounded like it was about to turn violent. Waited 5 minutes, reset the power supply again and it started up with no problems.

Sorry for your troubles.
I bought a UPS off craigslist for $50. One of the best investments I've ever made.

Can vouch for these. They are legit.

I have crappy outlets at my cheap arse apartment. I killed 3 motherboards before I broke down and got me one of these:
APC BE750G Back-UPS 750VA 10-outlet Uninterruptible Power Supply.
Haven't had a problem in 3 years after losing 3 in 6 months.

I have my experiences, and I know what has worked for me....
why not add to my knowledge base instead of coming out of the side of your neck?

Bump for another problem...
Turns out the motherboard was fried (suspect network connection to UVerse router was the path), so I bought a new MB, CPU and memory. All peripherals still worked. Reinstalled Windows 7 (64 bit) since I'd already paid for it, everything is back to the way it was.
Now, when I try and perform a backup (using Windows backup program) I get an error that the hard drive I'm backing up to isn't formatted NTFS, even after a complete reformatting. Drive was/is good, and I could open all the files on it before the formatting.
Any ideas? I've heard Windows backup sucks but this is the first problem I've had with it.

Didn't help my U-Verse gateway which comes with a battery backup unit. I've lost two of them this year so far.
