Please Read and Help. Fried?

post #1 of 23
Thread Starter 
Here is the story, We had a tunder storm and there was a big flash. Then we checked everything in the house no problem. Until I noticed that the tiny red leds on my mobo internal power button was not lit up. I tried to turn the computer on and nothing. So I disassembled it to check the power supply. It worked fine, but what I did notice was a faint electronic hum/beep comming from the mobo that would go in and out, when the power supply was connected and truned on. But nothing is burned up on the mobo everything looks fine. So, I check my internet and my wireless router seems to not be working but my modem when plugged in hard line to my laptop works fine. Also, everything else in my computer seems to work fine when I hard line it to the psu- dvd,fans,hdd,etc... So, now to the horrible question I must ask. Does this sound like my mobo and router are fried? Is there somthing I can check or do to test the mobo mainly? If it is fried does that mean that my cpu is also fried? I am so sad and do not know what to do next please help! This has never happend to me and this is the first computer I have built. It seems as if the lightning went through the network cabling and not the electrical outets. I still dont know why the modem would be fine and not the router or mobo. My specs are below. Thank you all.

Cheap routers not rarely tend to have heating issues, though I've never experianced any. And either way it has nothing to do your your PC actually working okay. The motherboard could be fried, though it isn't a rule that the CPU is too. When your PC is turned off, does the motherboard LED light up? Since you checked the PSU:

1) If the motherboard power LED does light, but the system doesn't power up, try sorting the two pins that go to the power switch and see if it boots.

2) If the CPU is dead, you can only replace it to find out.

3) If the motherboard is dead, you cannot know it for certain unless you replace it.

Try replacing the patch cable from the modem to the router.

Try resetting the router...and cmos. 9try leaving the router unplugged for a few minutes)
Unplug all power to your pc, rmove the cmos battery for a minute and while it's removed, hold the power button down to fully discharge the motherboard. Then replace the battery and try to power up again.

And just for the sake of it, check to make sure your 8pin cpu power connector and 24 pin motherboard connector are seated properly. (even remove them first and check for any odd discoloration/burn marks)

Honestly, it seems like the motherboard isn't getting enough power.
