Computer reboot due to defective motherboard capacitor

Symptom: A computer, its configuration is: Pⅲ866mhz (Dual CPU), ATi Rage Pro AGP 2x video card, MSI MS-6326 motherboard, 384MB SDRAM ECC memory, Seagate ST336705 LW SCSI 36GB hard disk, 15 inch color display, etc. The operating system uses the Chinese Windows2000 Advanced Server Edition and installs the ISA2000 Server Enterprise Edition. As the unit of all computer rooms connected to the Internet Proxy Server, the work has been very normal. But not long ago, when I double-click the ISA Management icon to manage, the server suddenly inexplicably restart, reboot when the machine self-test all normal, and then start to guide the Windows2000, when the progress bar to two-thirds when the restart, repeated problems can not be resolved.

Failure Analysis and maintenance: The spirit of "first soft after the hard" principle, the author press F8 key into the safe mode, with the latest version of rising 2004, no virus found. Open Control Panel → Double click system → open System properties → go to device management and look through all the devices without any conflicts. Reboot the computer and the symptom remains the same. decided to reload the Windows2000, however, when entering the graphical installation interface, the progress bar reached Two-thirds, the hard drive quickly read data, followed by restart. Repeatedly reload the system many times, failure can not be ruled out, according to the author to determine the source of the fault should be in the hardware.

Beginning to think that the SCSI hard drive is out of the question, using the tools provided by the motherboard to detect the SCSI hard drive, the results did not find any problems. Would it be a double CPU problem? A friend warned. To remove one of the CPUs, add electricity into the BIOS to adjust the relevant parameters of the CPU, restart the computer, when the Windows2000 installed to appear in the graphical interface, the progress bar flash past, the next work all smooth.

To this end, the problem has not been completely resolved, in this is the CPU has a problem, or the motherboard on the CPU socket out of the problem? Shutdown, remove the confirmed CPU, plug into another CPU socket, power, start, the old problem again appeared, so the answer is very clear, is the motherboard CPU socket problem, carefully check the CPU socket near the components, found that there are two capacitor yellow and some drum kit, the problem is to judge the motherboard. Contact the Customer Service Center, replace the motherboard, everything OK!
