What are the Symptoms of a fried motherboard?

Answer 1

A bad motherboard can show in several ways. If it reboots randomly for seemingly no reason, and especially if the frequency of the reboots increases, if it takes several tries to get it to start, and for Windows machines if they had been working, with good virus and malware protection, and stop with a blue screen with a stop error code. The most difficult task for a computer is to install Windows because of the checks performed to determine what hardware is present. If an older motherboard consistently fails to install because of a blue screen it is often a failed motherboard. A complete fail can show as a motherboard that will turn on but the power switch must be held in for 6 seconds to turn off. This is because power on is a hardware circuit but off requires the CPU to be operational to turn itself off. There are many other failure modes but those are the most common. As a general note, RAM rarely fails after 90 hours of operation and motherboards rarely fail new; they tend to fail as they age.

A bad motherboard will take your nerves really tight. Below are a few of symptoms you will start noticing before it is completely dead:

1. Delayed OS loading and sometimes failure in loading it

2. Heat up issues

3. Lagging: slow data processing and program running

4. upon giving a command, you will find a little delay in starting executing the program you want it to run

5. Heat sync fan will make a lot of noise

These are the most common symptoms I witnessed myself for the motherboard I had to bury in the waist bin last year.

Answer 3

The following are symptoms which point to mobo trouble:

1. Onbard devices start acting strange. For example the network card simply does not react with the network although does get IP addrss; sound device will arbitrarily stop working or crash its device driver

2. USB connectors might stop working

3. RAM frequency reported incorrectly (cpu-z reports this)

4. BIOS information changes arbitrarily or resets

5. A software reset will crash with a blank screen

Answer 4

The symptoms of a failing motherboard and a failing processor can be similar. In either case, the system may seem completely dead. Or it may lock up at random. Sometimes random lockups mean bad memory or that the BIOS needs upgraded. At other times, the motherboard or CPU is the cause. Sometimes the system will not even beep after you turn it on, and have no display. If the CPU is bad, there might be no display, and the fans operate at high speed. If the system fires up and shuts down, it could be the CPU or motherboard, though in some cases, it could be a bad BIOS (may still need a new motherboard if the BIOS is not removable) or there is a BIOS selection switch in the wrong position.

To help isolate the problem, there are some things to look for such as these:

1. You can connect the power supply to a power supply tester. If you have low or missing voltages then it could be the problem. If the voltages are excessive, not only would the power supply need changed, but possibly other components. However, low or missing voltages could mean that there once was a spike, so even then, other components could be damaged.

2. You should visually inspect the motherboard and the peripheral cards and look for signs of charring, cracked components, or bad capacitors. You can often tell if capacitors are bad by looking at them. They may be exploded (the vents on top are bent) or leaking. If this is on the peripheral cards, you should replace them as they could mimic a motherboard problem. If this is on the motherboard, it would certainly need repaired or replaced, but it is possible that the CPU was damaged by the voltage problems which either caused the bad capacitors or were the result of them.

3. Try a different video card. Sometimes a bad video card can mimic a motherboard problem.

4. Try less or different memory, and in different combinations.

5. Remove all but the bare minimum peripheral cards. If one of them is the problem, the machine should try to boot.

Answer 5

Well, there are some obvious ones like it doesn't work, slows your computer down, bad ports, like bad USB ports, old wires. There is a lot that can go wrong and cause it to go bad those are just some of the obvious ones.

Also if you look on the capacitors and the top is bulging or split and stuff leaking out then the board is bad. You might also detect the smell of something burning like insulation or arid smell.

When turning on the PC you may hear 1 Long and 1 Short Beeps. In general beep codes' rules, it means that your motherboard may be broken.

As mother board constitutes of all the external device component like input and output device like mouse, keybord, USB, LAN and wireless card and if these device find it difficult to find their device driver and often found without driver after reinstalltion or fomatting of file system or if it is compatible with all the file system these all symtoms suggest that mother board is not of a good quality.
