Hey guys, I've been reading online for a few days while trying to uncover why my computer will not stay on for very long.
Running Hot within minutes. Shuts down at 90deg.
Get hot faster when in BIOS.
Can boot all the way to the desktop, but once there it has been long enough to heat up and it shuts down or go into a "coma" type mode. It seems like a reboot but kinda stays in a black screen mode while the computer continues to heat up (Probably causing damage).
My process of elimination started with the power supply. While in the BIOS setup, the blue screen background would slowly start to dim and go in and out, then a shut down. So I assumed not enough power. Replaced the PSU with a better on and it did the same dimming type situation.
Second step was check the RAM sticks for damage or improper installation. I replaced the two sticks with one stick of a completely different manufacturer and speed and all that. No changes so it's not the RAM.
At that point I dismantled the entire setup. All drives out, cables out, PSU out, stick out, MOBO out and inspected all components. They all look good. Plugged everything thing in back nice and snug. Powered on. It seemed to last a little longer but then I realized that I should check the temperature. That's where I resolved my hunt down to an overheating issue, the BIOS temp sensor is watching as the temp. climbs from idle (60ish to 90) when it shuts off. Everytime it hits 90 deg in a matter of minutes or seconds depending on ambience around the CPU.
While inspected all the components I just want to mention that I did notice something very slight that may or may not be something. One pin in the Power Connector attached to the MOBO (for main power) is darker than the others. All are shiny either silver or bronze and this one and maybe one more are dark brown if not black. It's integrated so I'm not sure if that is an easy fix, or if it's even an indication of a problem.
So that's it, all pieces together and fix nicely. The computer overheats within minutes and to the best of my knowledge has been working fine for 3 or 4 years. The main CPU and the Southbridge Chipset get extremely hot to the touch.
What are my next steps without getting a new MOBO? Take the CPU out and re-heat doping it (probably all original from 4 years ago)? Install a better CPU fan or System Fan? Currently there are two. The BIOS tells me that the CPU fan runs about 4k RPMs and the System fan runs 2.5k RPMS which I'm not sure what is normal. They run that speed all the time, regardless of temperature. All voltages are within specs from the BIOS reporting.
I'm sorry this is such a long post, I've been pondering this all day and night for days. One more thing. The processor speed reported by the BIOS system information is an AMD Athlon XP 2338M which when I looked it up online doesn't exist. I'm wondering if this chip was overclocked to be faster then it should be without proper cooling. How can I tell an overclocked chip? There aren't too many jumpers on the board, and BIOS has a lot of options such as memory chip speed setting, which doesnt' sound like overclocking to me.
Any suggestions would be extremely helpful to me, and I thank you for taking the time to read this.
