Question about Abit IS7 Motherboard

1 Answer

How to diagnose:

I had some freak lightning strike action not too long ago. I had my computer on a surge protector, but I cannot get my computer to boot back up. I get lights and fans, but no beep or phoenix bios screen, and subsequently no boot up. Is there a way to load the bios via cd/dvd drive?

Sony Bravia KDl-55EX720 Struck by lightning.Red light shines.Nothing else works.

Claim on your insurance. lightning strikes reach voltages higher than a PCB (printed Circuit Board ) can handle. most of the chips inside will probably be bits of burnt glass now.

Power cord is bad, or Power On switch is bad, or Power Supply is bad.
Or the receptacle you have it plugged into is bad.

I have had a few surge protectors, where just ONE of the receptacles was bad.
(Hmmm, surge protector Power On LED is lit; monitor has power, printer has power, and amp for speakers has power. But no power to computer)

Last thing; is the printer closed? When opening to replace ink cartridges; is it closed now? Open it, and close it.

Montor is not responding to computer. Can the video card be replaced?

Whoa! Wait a minute here.

Let's not get hasty, and blame the graphics card.

Think of all the years of service..........

the long cold nights..........

graphics beyond compare, and......................

"Will Donna ever find true love?"

What? !O_O!

Oh yeah, where was I.........

You know the monitor cable, and monitor are good, because you are seeing No Signal, or going into Sleep Mode.
The next logical thing IS to suspect the graphics card.

The actual first thing to check is the Power.

A) Surge Protector:
Check to see that THE receptacle in the surge protector, that the computer is plugged into, (Or was), is good.
I have had a FEW surge protectors where just THAT receptacle, was bad.

"Hmmmm,....LED power light is on for the surge protector. Monitor, printer, and router all have power from the surge protector."
Tested the receptacle that the computer was plugged into, with a table lamp, and NO power.

2) Power Supply:
If you see LED lights on, and maybe fans spinning, it doesn't mean the computer is getting enough power.

A) If ALL of the LED lights were on at once, they would use less than 1 Watt of power.

B) EACH fan uses 2 to 3 Watts of power.

C) A typical Processor can use 51 to 125 Watts of power. Just depends on what Processor it is.

A power supply with a weak voltage power rail, will not have enough power to turn the Processor on.
No Processor, no computer. No computer, no video signal to the monitor.

Test the 3 main voltages for the power supply with a multimeter, or use a KNOWN to be good, and compatible, power supply for a test unit.

[ 3.3 Volt power rail
5 Volt power rail
12 Volt power rail.
All are DC voltage ]

Power supply checks out? Then you may, or may not, want to obtain a graphics card, and try it.
Why -> may not?

Because the electrical damage may go further, than the graphics card.
May have fried the motherboard.
Hopefully not the Processor, and Ram Memory, but...........?

[ The motherboard has Integrated Graphics. If you are plugging into the VGA port on the back of the computer, you are using Integrated Graphics.

If the Surge Protector, and Power Supply checks out, AND you have access to an economical graphics card, (Or can borrow one), try it.
Make sure the computer is unplugged from power. FOLLOW Anti-Static Precautions. Physically install the graphics card.
Monitor cable to graphics card.

When you first turn the computer on the graphics will be rough.
You still have to install the drivers]

[An economical multimeter can be purchased for as little as $8 to $12. Available in a multitude of stores. An auto parts store is but one example.
Need guidance in using it post back in a Comment. Include the manufacturer name and product number of the multimeter ]

For additional questions post back in a Comment.

When i connect the lan wire my mother board shows lan not connected why/

Either the cable is defective (it has a break inside it so try another one) or the onboard LAN chip was fried by the power surge generated by a lightning strike that came in your vicinity.
That is unfixable, disable the onboard one from the BIOS and install a simple PCI LAN card in its place.

We had lightening strike, power surge.

if the problem is not turned worse then the motherboard can be repaired easily.also the modem if faulty can be repaired or replaced as it wont cost much.but yes it is necessary for a technician to manually diagnose this to see the current state of mother board.

Surge Protector

Surge Protectors are devices that usually you plug your equipment to.. and it protects it from Voltage Spikes that would otherwise destroy the device without it.. saddly not all Surge Protectors are the sam.. some are completely useless..

If you are really serious about protecting your PC not just the hardware but also the data and your work.. might as well invest on a UPS(Uninterrupted Power Supply) unit.. it has everything a surge protector can offer and more..
