Strange behaviors of my k6 3+ 450acz

Hi there!
it's been a while since the last time i posted in this forum. Recently i came back on messing with my k6 retrogaming rig, and discovered something weird.
Actually, during the last period i used it (18 months ago) i noticed lot of crashes and general instability. I couldnt really figure out what was that, since i tested ram, hd.
The CPU, which used to run fine at 550 2.0v, now even at stock setting was unstable and crashing, locking up the pc.
This behavior made me forgetting about this PC for a while.
Yesterday, out of boredom, i started messing up with it again, and the instability was still there. I reseated the CPU, reapplied termal paste, even used a thunderbird stock cooler (much better then k6 one).
Temps looked ok in bios, both before and after tests, but it was still unstable (it would crash even copying 1gb of files from 1 hd to another).
Out of desperation, an idea came up to my mind:
Recently i have OCed my main rig, a phenom II, up to 3.8 ghz at 1.45v. While finding stability i noticed that this kind of crash (complete system lock up) is mostly a CPU problem (while blue screens are mostly RAM problems), which could usually be temp related or voltage related.
Since temps where fine i tried to up the voltage, and after a few tests, found that at 2.2v it was mostly stable (i say "mostly" cause i dont have any long test on win9x to use) both at 450 and 550 mhz
That's kinda strange, because it requires an overvolt even at default speed, but reality is reality, now is working ok, before it didn't.
Did anyone else here saw a behavior like that out of their setups?
I think it might be power supply related (age might have made it unable to keep the setting 2.0v at real 2.0v), or MB related (some voltage drop underload, im using a P5BV3+)
Btw i also noticed a strange thing on the CPU pins while reseating it and applying thermal paste: 4 or 5 pins on the outmost line of pins are partly "red" instead of gold.
I dunno if it's rust, it's normal, it's just some gold paint there going away and showing the copper under it or not, but maybe this thing is also related to the problem
