About a few months ago, my computer starts to freeze randomly. Initially I thought it was too rare an occurrence for me to take notice of, but soon it became much more frequent. Then I had to start looking for the source of problem.
When it freezes, everything stops and the sound starts looping. I have to shut it down because it won't restart by itself. After the first occurrence, this freezing thing tends to become more and more frequent if I keep on powering on the computer over a period of time (5 hours?). It always passes POST, but sometimes freezes in BIOS.
I suspects that the motherboard is the faulty component, even though I haven't done too much testing to confirm that other components are all perfect. My suspicion is based on the fact that the voltage settings do not match with the readings. For example, the core CPU voltage reading is about 0.5V above my setting, and the DRAM voltage is about 0.6V below my setting (I can see it in the BIOS "PC Health Status" section/CPU-Z). Moreover, I don't think the core CPU voltage is stable enough, but I don't remember the exact difference between the recorded maximum and the minimum voltages .
Base on these very limited facts I have provided, how sure would you be to say that my motherboard needs replacement? In addition, is it possible that the sensors are faulty instead of the entire board? Thank you all in advance!
CPU: AMD PII 1090T
Motherboard: Gigabyte 970A-D3
RAM: Kingston HyperX KHX1600C9D3X2K2 (4x2GB)
Graphics card: XFX HD6950 [Flashed to HD 6970]
Hard disk: Hitachi 2TB (can't remember the series no.)
I also have a 1090T and it freezes sometimes (really randomly). Sometimes while gaming, sometimes while writing/programming...
The MoBo I use is a ASUS Crosshair IV Formula. Some People wrote that this might have problems at the Power-connectors, but i guess it is the 1090T that makes the problems.
Maybe i try to change the CPU just to see if the 1090T is somehow damaged...
