I restarted a computer today (an Asus P5KPL-CM, with an Intel Dual Core E2180 Allendale, no overclocking) and heard a beep code (always a scary thing). The code was three…four. The latter four may have been a bit longer or slower. On another restart (it had been running headless at first), a message came up during POST, “CPU Over Voltage!” The exclamation point is in the POST message – which is kind of alarming.
In going to the BIOS setup screens, I took a look at the CPU voltages. The readings went from white text (normal) to red text as they fluctuated. Here is what I saw (first number is the white number, the reading that was mostly there, the second number was red, and only flashed randomly and sporadically):
V Core Voltage: 1.320v/.296
3.3V Voltage: 3.12v/1.072
5V Voltage: 4.864v/1.587
12V Voltage: 11.880/5.12
Is this like having the oil light on a car go on, in that I’d better shut the system down and leave it off until I figure out what’s wrong?
As for figuring out what’s wrong … is there anything to do short of replacing parts until the message goes away? In what order — is this more likely a board issue or a CPU? Could RAM be affecting it? The PSU?
Could this be OS-related? It’s running Linux (Ubuntu), and I’m awfully new at it. I’m also having some problems, which will likely be another thread (when it rains, it pours). I was getting the “User’s $home/.dmrc file is being ignored…should be owned by user and have 644 permissions” error, which in following some fixes on the net that worked for others, led me to start getting a “The Gnome session manager was unable to lock the file /home/Rhythmdvl/.ICEauthority; Please report this as a Gnome bug…” When I try and boot the system, I now get the beep codes, then it starts loading the OS, then I get the first error message, then the second, then I enter the name/password, then it pauses, and starts the cycle over again with the first message.
I have no idea if the two are related in any way, or if the first problem was there for a while but I didn’t notice it until I started restarting the machine.
Not being an overclocker, I have no idea what these mean or where to start. Any help?
Thanks,
