Machine freeze up randomly. Must do a hard shutdown. Seems like a motherboard failure

Posted by on

    This seems to be a generic problem with this gateway e-155 tablet. (Piece of *&$#) I've tried everything I can think of. I've changes out the hard drive with a known working system. The same with RAM, from another e-155, still no luck. I've replaced the motherboard and that USUALLY fixes it, but in a case or 2 that has not. I've replaced cooling fans, heat pipes, used GOOD thermal compound. I'm at a loss, and now that MPC is going under, I have 400 of these things to support with no support from MPC (Gateway)
    Any more ideas?

  • ronbeck Nov 09, 2008

    We are supporting about 400 of these things. The cpu is not removable in this board. All our power bricks are being used on other machines, plus this will happen when on battery.
    I tried keeping everything cool by using cold spray on the "Radiator" to keep the cpu and I believe the northbridge chips cool. I also chilled probably the southbridge chip which was the only other warm component on the board. I believe there is a specific component that is the problem. Since it is intermittant I think it's heat related but cannot pin it down. With so many similar failures someone must be aware of it, but so far I haven't found them. Also, since MPC is in chapter 11 I'm really afraid I will have to eat these warranty costs. We are self maintainers for gateway, and WERE receiving replacement parts under warranty. Now I need to be more resourceful. Thanks again for your help!

Freezes and crashes are generally caused by some sort of instability in the computer system.

The following is a list of specific problems that can cause instability along with what to check when troubleshooting each.
Viruses can cause instability.
Run a virus check on the computer to look for a possible virus.

Conflicts can cause instability.
Check the Windows Device Manager to see if there are any yellow exclamation marks or red Xs beside the listings for device classifications. If there are, contact Tech Support.

Buggy or damaged software applications can cause instability.
If the system is less stable when certain software programs are running, shut down those programs and see if the problem continues to occur. If the problems stop, chances are that those software programs are causing the problems.

Buggy, outdated, or conflicting drivers can cause instability.
Check manufacturer web sites for updated device drivers for the various devices installed on the computer system, such as: printer drivers, modem drivers, video drivers, sound drivers, USB device drivers, etc.
Update one driver at a time and see if the system stabilizes. If this doesn't work, it may be a hardware problem, so contact Tech Support.

AC problems can cause instability.
Check to see if the computer system is plugged into an overloaded outlet.
Make sure the computer system is plugged into a surge suppressor.

The installation of new devices can cause instability.
There are three typical symptoms that point to this problem:
The computer system fails to boot, freezes during a boot, or freezes during an operation for no apparent reason.
The system fails to recognize the newly installed device.
One or more software applications fail to function as expected after an upgrade.

Hardware failure can cause freezes

Fan failure, cpu failure, memory failure, could be also a cause of freezing.

Keep track of the hardware and software that is added to a computer.
The addition of new hardware and software can often cause problems to occur.

    Usually after the motherboard has been replaced, this kind of problem disappears.
    Did you check the power supply? Did you try replacing the CPU processor from one machine to another? Sometimes works.
    Did you try with a NEW motherboard?

My HP a749c randomly shuts down

sounds like you have a hardware problem. I thinking it is the motherboard, but you can try by taking out other parts (cd drive, hard drive, ram, etc) and if the part does not change anything then it is not the problem part and can be placed back in.

Dear experts, I have an old IBM PC M55 desktop type 8142 . nowadays it randomly shutdown. I had checked PSU and cooling fan is OK. I eliminate windows/software/virus problems because in BIOS mode the...

It is very possible that it is the motherboard; they tend to be unstable, especially old voltage regulators that regulate the power to the CPU. With the number of things you have eliminated, I would agree that is the MoBo, and the solution would be to replace the MoBo.

I have a gateway desktop that is beeping before post. It beeps and will not post.

It depends on the motherboard model, but here is an example of the error codes for a gateway:
Beeps Error Message Description 1 Refresh Failure The memory refresh circuitry on the motherboard is faulty. 2 ECC Error Error Checking and Correction (ECC) is supported on this product. 3 Base 64 KB Memory Failure Memory Failure in the first 64 kilobytes (KB). 4 Timer Not Operational Memory Failure in the first 64 KB, or Timer 1 on the motherboard is not functioning. 5 Processor Error Ther processor on the motherboard generated an error. 6 8042 - Gate A20 Failure The keyboard controller, 8042, may be bad. The basic input/output system (BIOS) cannot switch to protected mode. 7 Processor Exception Interrupt Error The processor generated an exception interrupt. 8 Display Memory Read/Write Error The computer video adapter is either missing or its memory is faulty. This is not a fatal error. 9 ROM Checksum Error Read-only memory (ROM) checksum value does not match the value encoded in BIOS. 10 CMOS Shutdown Register Rd/Wrt Error The shutdown register for complementary metal-oxide semiconductor (CMOS) random access memory (RAM) failed.

My computer is shutting down on its own. Is this

Scanning computer to eliminate malwares, spywares and the viruses from your laptop.
2- Repairing and cleaning Windows registry.
These two tips are found to be very helpful to fix the laptop shutdown problem. Almost all the computer users surf internet which could result in viruses attacking your system. Some of these infections are really pesky and cause the machines to shutdown randomly.
The registry errors, however, are the internal errors and can become a cause of system crashes and freezes. The registry keys shall be in good health to keep a system perfect.
When I noticed my laptop keeps shutting down everytime, I tested the Intel Software Partner, RegInOut to fix the random shutdown problem with my laptop.

Random Restart or Computer Freeze

what you did is OK for minor fixes. mostly for application error.
you need to format the hard drive and install the OS again in order the OS to work properly. you may have some file that is left over that is cusing the shut-down.
