Osbourne OCC1 problem - progress 2....

OK, now the wobbly video fault's gone away - hurrah! Of course, this could be because the machine's been on for longer than it has been in years; perhaps it was a thermal issue. When powering off/on, I notice a little flicker of crazy-video now, then it settles again. Maybe I'll leave it switched off for 5 mins & see what happens. MEMTEST still reports the same memory errors, however, thus: ADDRESS: 4081 BAD BITS: 08 ADDRESS: 40C1 BAD BITS: 08 ADDRESS: 4181 BAD BITS: 08 ADDRESS: 41C1 BAD BITS: 08 etc., through to: ADDRESS: 6481 BAD BITS: 08 ADDRESS: 64C1 BAD BITS: 08 Memtest itself runs a number of different tests; it's currently crashing or resetting the machine at random intervals. Longest successful test lasted about 1/2hr (successful insofar as it didn't crash). Now running for 2-3 mins before crashing... Note: This is memtest only, I've not tried any other programs yet... Hey ho, more testing to go... If the video prb is thermal, I'm still guessing it's related to one of the mainboard chips, rather than the monitor itself (given that it will display random characters, rather than what I'd call analogue effects). Anyone got any clues as to which one? I'm also wondering if it's a RAM select chip, rather than the RAM itself? Cheers! Ade. No virus found in this outgoing message. Checked by AVG.
