My system got very instable out of the blue.
What happened so far...
I've got a nice system (I think) and it had been running for over a year without any problems, then all of a sudden I got blue screens with a Machine Check Exception error.
Because it started happening when I was playing a game I thought it could be a graphic card problem, I did misflash the graphics card once (Leadtek A350, GeForce FX5900XT)...
But that wasn't it, replacing the card had no effect and my 'old' card checked out fine in another machine.
So I did a search on the net and found that a Machine Check Exception error could be a memory problem (also considering that my computer was now randomly rebooting, even when only working on my desktop) So I bought new memory (2x512 MB PC3200 Usi), it didn't help.
I thought that maybe my MoBo didn't like this brand of PC3200 memory, so I underclocked it to 333 mhz. no effect.
The next step was replacing my MoBo, a friend just bought a new computer and his old MoBo supported my hardware.
And yes, some light on the horizon, it worked and seemed to be stable.
But wait, I don't have a Athlon XP 2000+, I have a 2600+, oh, I see, the FSB is still al 133 and it has to be 166 let's get it up to 166!
This is where it goes wrong...
every setting above FSB 145 causes the system to become unstable and / or hang, can't even boot to XP.
I've checked the MoBo manual and internet and my processor indeed needs the 166 FSB, so something is wrong, but what?
Every other bios setting is 100% oke.
So has my processor become defective?
But why does it run flawlessly at FSB 133?
Is it overheating? Can't believe that, have a good Cooler Master cpu cooler and the sensor 'says' that the processor isn't going above 50 degrees Celsius, and that's a great temperature for a Athlon XP 2600+.
My case is also well cooled, not exceeding 29 degrees Celsius.
Anyone got a idea?
I'm starting to blow smoke out of my ears, I'm getting desperate.
Please someone, shed your light..
