My A4000 keeps freezing!

[samanosuke]

Please help me! I don't want to have to resort to taking my A4K to those butchers at Analogic!

The problem I have is that my A4K freezes not long after booting up. The current spec is OS 3.0, 3.8gb HDD & 32x IDE CD-ROM via Power Flyer 4000, 16mb RAM and a Picasso IV card. Workbench boots up fine and the system appears to work fine for about 10 minutes or so until it completely freezes. The display still remains - no blank sreen, Guru Meditations or suspend/reboot requesters - just a static Workbench screen. It all seemed to work fine until I had to repartition and reformat the hard drive as thanks to my lack of Amiga knowledge the only HD install software I could use at the time was some crap from Analogic that came with a 2.5" A1200 HDD years ago. It set up a workbench partition with only 10megs so eventually the time came when I had no more space to expand the OS and had to bite the bullet and wipe the whole machine in order to use HDToolbox and repartition the drive. Another point of note is that the memory SIMM slots are broken and the SIMMs can flap about. Still, WB says I have around the 16 megs that I should. I wonder, if they were loose and the machine suddenly lost access to code stored in one of the SIMMs would it cause a system freeze like this? If so I can probably get my machine repaired at a reliable PC centre rather than Analogic.

you could bet for sure . . .

When the system warm up, the SIMMs contact will become loose and the system freezes.

Try to fix the broken one, in some way but . . . all the 4 sockets are broken?

My A4000 used to freeze like that. Turns out it was a dodgy CPU socket on my Cyberstorm 060. Applying pressure to the 060 would make it run reliably again... but i've now replaced it with a CSPPC which runs perfectly stable (except that it keeps working itself loose in the Power Tower... *sigh*).

the simmsockets are dodgy on some A4000, sometimes putting preasure to the "locking tabbs" in form of some cardbord or simular helps keeping the simms in place. Having them flopp about will surtanly give you noneworking system. Also if that doesn't work as said already, clean the CPU slot (and the connector on the card) and if possibly try another CPU card.

try this: use spiritus to clean the simm socket(s). If possible, try to catch the "running away" simm with a plastic stripe (such as for cables, etc.). If doesn`t help then check your system cooling, Hard drive cables, and hdd/cd MaxTransfer settings. I`ve had problems with my harddrive tape in my a1200. When i replaced it, some problems did not solve, so i needed to lower the Maxtransfer. My ami works perfectly now... it hangs maybe twice a week...
