About a year ago, I built a system based on a MSI KT3 board for a friend of mine. After about half a year, he started experiencing problems. His computer alsways shut down as soon as he loaded the CPU quite heavily.
I first assumed that the cooling was the problem. As I tried different cooling (I exchanged the Alpha PAL8045 for a 80mm Tigerterm block) nothing changed. So I checked everything but no problem to be found.
Suddenly the system didn’t turn on anymore. When I put his Athlon 1700+ in my old mainboard (I had a KT7 Turbo back then) the DLEDS gave the same error: 4x red, meaing a damaged CPU. Although there was no fysical damage done to the CPU, it seemed dead. I brought it back to the reseller we bought it from.
Putting my Athlon TB-C 1,2Ghz on the board didn’t make any problems, it worked like it should do. So I concluded that the KT3 board was fine.
As we did not hear from the shop in a couple of months, my friend today decided to get a new CPU. He bought an Athlon 2100+ (Tbred B core). Guess what: the system boots, but automatically shuts down after a random number of seconds.
So what’s going on here? The auto shutdown should only be initiated by an overheated CPU… but as it never goes above 50C I don’t think that to be a problem…
Anybody? We’re getting quite desperate… all the parts seem to be working fine…
