I think I really messed up (CPU)

[cali99boy]

I know I was dumb but......

Ok... there was a lightning storm here in Orlando earlier today. Well.. I continued using my computer cuz I had no idea why people say to turn off electronic stuff during lightning storms...

Well.. I found out. I think my other Computer(main one) is busted. Not sure what to do(buy a new cpu,.. or buy a whole new mobo combo etc). If any of you guys have any idea whats wrong or what needs to be fixed/replaced,.. please so say.

My comp will turn on... but will not POST. I hear nothing but my fans. And nothing displays on my monitor.I'm typing this with the other spare computer(POS though, and would like not to play with this one)

Any help appreicated. Atleast the Athlon XPs are pretty cheap now

try restting the cmos?

EDIT: btw, this belongs in technical support.

Well...for future use - everyone that values the investment that is their computer should get a UPS unit, or at the VERY LEAST a surge protector.

To address your problem - if your house suffered a blackout due to the lightning arcing on a local power junction, chances are you should be okay. Your circuit breaker can usually prevent any real damage. If the lightning arced onto your house specifically, then you might be in trouble. Try resetting the CMOS by shorting out pins 2-3 on your CMOS jumper header on your motherboard. If you know the procedure stop reading here, otherwise, short out pins 2-3, leave it for roughly 10 seconds, then put the jumper back on pins 1-2. Try starting your system to see if it posts. Sometimes a good CMOS reset can do wonders to revive "dead" computers .

Yes... I have a surge protector but I guess it didn't do anything

Thanks.. I will try and see what happens

 

[cali99boy]

Ok.. I just tried to reset the CMOS.
(CMOS Clear)

But it didn't work. Normal is 1-2 (Default), I changed the jumper so it would be 2-3 (Clear CMOS). I left it on for 10-15 secs and put it back to 1-2 and nothing happens. The mobo lights up and all the fans run but no activity. Still will not POST.

Any other ideas appreciated.

did ur computer just all of a sudden shut down? or did it not turn on after u shut it down?

 

[cali99boy]

it all of a sudden shut down.. Power surge I suppose went thru my house. My whole house got power shortage for like 5 secs and then back on again.

 

[HalfCrazy]

Where I live our power drops out now and then for just like 2 sec. Just long enough to make your computer reboot or shut down. So I went out and bought my self a UPS for my computer. Next time the power goes out I will still be on-line and surfing the net.

 

[cali99boy]

Lol,.
yea I've been looking at some UPS deals going on after this unfortunate incident heh

May have toatsed something in the power supply....

Hapend to my moms computer about 3 months ago and I thought everything likely was toasted...However I had a spare power supply and tested that and it worked....

Got a spare try that and save the costly process of trying to guess the culprit....

 

[billyjak]

That is rpecicely why you get a very good power supply. like PC Power Cooling ones.
They can take the punishment. Look Here
My Power also went out twice the other day and I leave my computer on 24/7. when I got home I just hit the power switch and presto.
Also Invest in a real good Surge suppressor, them $30.00 TO $40.00 ONES don't cut it.

 

[LongCoolMother]

this happen to me a week ago.

turned out my stupidass PSU fried my mobo AND my tbird. sucked like hell.

i had to upgrade to msi k7t266a pro2 and an athlon xp 1800+.

heres a thread i posted about it.

Sounds like your power supply is dead. I had a dead power supply once, it supplied enough power to run the fans but not at a high rpm. Get one of those cheap Power supply testers from a computer store.

 

[cali99boy]

I don't think it was my PSU. I connected a different PSU to my mobo and still no-go.

I broke down and ordered a MSI KT3 (Via KT333) Ultra from newegg today.
Theres no chance that anything else got fried right?

At first I thought it was my CPU and so I put a new one in and still no luck. I just don;t want to keep guessing what the problem is...if I keep this up, I'd probably end up buying a whole new computer by the time I figure out whats wrong lol

In my experience it is much more often the case to suffer damage from lightening through a cable modem or phone line than you are your power line. Power lines are protected by fuses, breakers, ground wires, and quite often a surge will most likely kill your power supply. Since your fans come on your PS sounds OK.

Cable and phone lines on the other hand typically have little to no protection and are litererally just wires strung outside. I've had several users loose machines via their modems during a lightening storm, so just turing off the power doesn't protect a system in my experience.

As far as what's fried, you just gotta test it one component at a time. There is no way to really tell without testing.

I had one user who had lightening blow up their modem, once the modem was removed the machine worked again. So I'd suggest that.

(BTW - high voltage is strange ... this user lost their modem, but their phone and answering machines on the same line were fine ... )

Your power supply sounds like it is OK. I would remove every PCI card and leave just the Video card in and what ever else you need to boot your computer. You can also remove one device at a time to see which one is fried. I have seen the same problem before where the modem is fried and it will keep the computer from posting.

 

[cali99boy]

i removed everything but the video card. And still no POST.

I don't think its the Cable Modem because I connected that to a Router and connected like 4 other computers to the router and my internet connection with the other computers are fine. I also tried disconnecting my NIC card as well.. Still nothing.


Also, is there a chance that I damage new components by putting them into my "bad" computer for testing them? I remember once where I had a bad component, not sure which one and I took my CPU out to test on my friends mobo. Afterwards his computer wouldn't even POST as well even after I took my CPU out and replaced it with his.

 

[unclebud]

can one fry the cpu by setting the clk speed too high (left voltage @ default)? reseated the battery and went into bios, came back out, wouldn't show video
msi-6366 d-led is saying processor not secured properly (bought from boss) or damaged
got tired and left. will work on it some more
thanks...
