PC Zapped By Lightning!!!!

post #1 of 22
Thread Starter 
Hello everyone, my friend's rig went out last night during a bad storm.

Now it's hard drive light only sputters slightly, and his PC fan sort of attempts to turn but won't. (Other wise nothing even comes on)

At first I told him his PC is probably toast, but, it was an $1800 rig and he doesn't want to just trash it with diagnosing exactly what was damaged and attempting to fix it.

My plan was to first try a new outlet in the home, then try to swap out the PSU and see if that helps.

My question for everyone is: What steps, and in what order, would you take to diagnose and possibly fix the problem?

Does he have homeowners insurance?
A friend lost his entire system and a TV in a similar instance... insurance replaced everything.

Hi.

Sorry to hear about your Friends dilemma

Imho:
  • Test the PSU with a voltage-meter (jump the PSU and see what the outputs of the voltages are).
  • Dismantle the rig and inspect each component.
  • Clean and reassemble with the bare minuimium of hardware and see if it POSTs.
  • If available, test the unit with all native hardware, but rotate in one known-working component each round of tests.
  • If available, test each questionable component on a system that is fully-functional.
  • Find receipts, and initiate RMA/return process if possible.

Imho, your inital thought is spot-on: test PSU first. preferably independant of any other hardware.



Good luck.

PSU would be first.
Probably after that would be motherboard and then the rest of the components.

That's a good idea, I'll have to suggest that. He is a renter, but, still he may have renter's insurance.

Lets assume just for the discussion he doesn't, what would you do to diagnose what was fryed?

1) If his case has a chassis speaker, hook it up to see if the motherboard gives any POST error codes
2) If his motherboard has an LCD display for the POST, check the codes
3) Make sure all the cables are plugged in, check power cables for burnt pins, scorching etc
4) Try taking everything out except the cpu and a minimal amount of memory. If the fans stay on, it is probably one of the components you took out.
5) More than likely, the problem is the motherboard. Replace that first
6) Go to homeowner's insurance company

I would test each component in another rig. It wouldn't do any harm. Also, tell him to buy a surge protector

Poor guy, that happened to my old PC however the only thing I had to replace was the power supply and it worked perfectly again. I suppose that would be my first try and then I would try to swap the parts. If it is not his power supply then I would pin it to 1st.Motherboard 2nd. CPU 3rd.Ram. Depending on how good of mates you are perhaps you could let him use your motherboard to test it, or cpu, or ram, or PSU.

I had this happen to me twice. The first time the PC didn't turn off it just flickered and my network card never worked again. The second time it was just the PSU. I would test all the components in another system if you can.
