Asus P4V533 Motherboard makes Two Beeps then it Freezes
I have been using Asus P4V533 for 10 months, but it is only now that I
have experienced this problem. For over a week now, while I am inside Windows XP Pro, the motherboard will suddenly sound two beeps, then my OS will suddenly freeze. It is not an OS problem, since it also happens when I am inside the BIOS menu. Can anyone suggest what might be the possible cause? My CPU fan is operating normally. Can it be the power supply or the motherboard itself? Unfortunately, I don't have other PCs to perform testing (like swap components). |

The last page of this document, suggests checking the memory DIMM is properly seated. But what you are hearing, may not be classed as a POST code as such, so the table may not be applicable. http://www.ami.com/support/downloadd...pdf&FileID=572 I would start with a memory test. Get a copy of memtest86 from memtest.org . There are a couple of versions - one version will format a floppy diskette with custom test code (no file system), while the second version is suitable for burning an ISO CD test disk. If you have a floppy drive, use the first of those two methods. Once the floppy or CD is prepared, simply boot from it. It could also be that the hardware monitor is detecting a problem, and the next time you boot the machine, enter the BIOS and go to Power:Hardware_Monitor page. See if any listed voltage or monitored fan speed is out of spec. Maybe your CPU fan is running too slow or something. Your ATX power supply outputs (+3.3, +5, +12 etc) should be within 5% of the nominal value. Due to measurement error, I would get concerned if the value is high or low by 10%. It could be, that when there is a computing load, the voltage is dropping out. You can try Motherboard Monitor (MBM5), for which support is discontinued, but perhaps downloads are still possible. Or you could get a copy of Asus Probe. (Go to the Asus download page, and enter "tools" as the name of the motherboard, and a list of utilities will appear instead. The following link is a shortcut to getting there. It looks like version 22304 is the latest.) http://usa.asus.com/support/download...Tools&Type=All MBM5 can log voltage and fan readings to a text file. Asus Probe does the same thing, only the results are available in a less convenient graphical form. You can get a copy of Prime95, from mersenne.org . Use the "Torture Test" mode, which does a computation for which the answer is known. The program can detect a CPU computation error or a memory error (as memtest86 may not find all speed related faults). The program, as a bonus, also runs at 100% CPU, and while Prime95 is running, check either MBM5 or Asus Probe, and see if just after Prime95 torture test starts, a voltage or fan speed is dropping out. Only install one monitor program (i.e. MBM5 or Asus Probe) but not both of them at the same time. On some motherboards that use the SMBUS for the monitor chip, the two programs interfere with one another, due to the lack of a semiphore for hardware use in Asus Probe. HTH, Paul |

you could try reseating the cpu,ram and vga to see if it clears!
