Bad Board?

[Checkmate]

Local area has had some pretty nasty thunderstorms the last week. Had a client that had a lightning strike right outside her house, and had power go out. A couple days later she calls me with her pc won't boot past Acer splash.

Here is what I have done:
Opened case, tested PSU: Good
Checked all capacitors: Appear good (no swollen caps, leaks)
RAM: removed, powered with one stick in each slot: Still Acer screen
Removed CMOS battery: Issue remains

This will not load boot menu, nor load into HDD or a boot CD as first device.
BIOS recognizes HDD and DVD/RW.

Any advice as a further test, or am I correct in calculating bad board?

Opened case, tested PSU: Good

Using a known good power supply or a relatively useless power supply tester?

 

[Checkmate]

Known good PSU, it's the bench PSU. Never leaves
And just tested with known good ram, still nothing

try to remove certain things while booting, remove the cd drive, remove each memory stick, remove any cables that may be on the board.

How long have you let it sit before shutting it down? Ive seen some laptops take 20 minutes to finally boot because a ribbon cable is bad.

A few things you can try:

Discharge the capacitors by removing the power sources and holding the power button for ~30 seconds.
Make sure only the bare essentials are connected (Logic Board, RAM and Processor).
Reseat Processor

@Knightsman have had it sit for near that long, and still won't move. If I don't catch it within about 20secs of splash, then can't reach BIOS or the freezing boot menu

@ATT have tested with no HDD or DVD and still ends at splash... doesn't even yell that there is no HDD or missing hardware

Any PCI cards? Front panel USB connections? Case fans?

 

[Checkmate]

No case fans or cards on system. Only front USB, but hadn't disconnected them yet, just tested with disconnected. Still only one beep, acer splash. No errors about no keyboard either.

Have you disconnected the hdd

Have you disconnected the hdd

Yes he has, two posts up.

Sounds like a bad board, assuming you tried the other options I listed. Probably not worth spending too much time on it.

 

[Knightsman]

If its freezing that fast, sounds like bad mobo.

Sorry missed that, yes failed M/B that's all that's left.

 

[Checkmate]

Was thinking that. But hate to tell a client they need a new mobo. Only thing I did not test was reseat the processor. Usually the case with lightning strikes.

 

[Knightsman]

Do you have a good parts supplier? If not let me know the specs, I get good prices on OEM part from the warranty company I do work for.

Be aware that the processor might be affected too after the lighting. So, it's better to warn the customer

If the mainboard has a jumper or other means of clearing CMOS, might give that a shot. Has brought more than one machine back to life for us.

Possible Prossesor Failure

This can also be caused by a Processor starting to fail. If yo have a spare test processor that is compatible with this Mobo try it. It's worth the effort.

Acer

Recently had an Acer come in, and it turned out to be a bad processor. I had only ever came across one other failed processor, also from an Acer.. Someone else suggested processor, and its really easy to overlook this, as they rarely go bad. In such a case, its possible the storm damaged the processor and the motherboard may have some unknown issues as a result. May not be worth the effort in the end.

You know you can edit your post if you mess something up, like a say a company graphic?

Also, stuff like that can be put in your signature if you plan on posting it every time.
