Title: Hardware Inconsistencies (a little scary again for me!)
Post by: 3246251196 on May 25, 2006, 11:02:38 PM
just left my amiga 1200 on there. booted into WB and just left it whilst on PC. now, i left it for about 10-15mins and all of a sudden the CLICK noises from the DFs stopped - the computer FROZE.

also, when i was changing the date on WB this happened.

i am getting random freeze ups (this time it has nothing to do with WHDLoad / TCPIP stack)

just pure freeze ups (though when it boots i SOMETIMES get the SOFTWARE FAILURE screen)

what is this!???

thanks

Faulty accelerator/RAM maybe?

Try filling the RAM disk with files from the hard disk until full and then remove the entire contents- does the Amiga crash?

Boot the Amiga from the Workbench disk and monitor it- do you still get crashes?

i havent tried those yet AKit. BUT, i left it on for so long yesterday and no problem

do you think it is OVERHEATING?

 I can only say that random freeze ups can be caused by:
- OverHeating: Touch all of the ICs/Heatsinks of your Amiga system with your finger to see if this is the case.
- Dust/dirt: With the help of little moist can produce short-circuits.
- Flaky software: Remove all of your installed patches and commodities and see if this helps
- Not enough Power from your PSU: This can be a real issue if you have a lot of devices connected to your system. Remove as many as you can and see if stability improves.
- Bad connection between a card or a IC and the motherboard: Remove them, clean the contacts and re-plug them.
 Well, this is all i can think of right now. Let us know if any of these helps.

check if acelarator,ram,ide cables are fitted ok. change the ram module if you have any spare.

i do have 2 spare 4Mb modules. i might just leave it until tomorrow though. leave it on for a long time. personally i think its OHeating. i keep it on for to much (and redundantly quite frankly!)

A quick easy test is to totally fill then totally purge the RAM disk- this will test the integrity of the memory and a lot of the accelerator functions.

If you get that test out of the way, you can start looking in other areas.

okay. i will leave it till either later or tomorrow. i will fill the RAM DISK then empty it again. see what happens. i am confident in this acc' card though tbh. to re-iterate, i think its OHEating

What kind of accelerator are you using? 040s and 030s at 50MHz can get VERY hot.

well this is just a 1220 at the mo. @ 28MHz CPU/FPU 4Mb FM

What revision motherboard do you have?

aminet has several real memory test programs, if you think it might be the cause..

okay. i filled up RAM disk until it said FULL. then i took out everything and moved it all to the "desktop". there was not a problem. so, fill-flush test worked fine. i rebooted. left it "clicking" (just boot to WB but no actions) and AGAIN it freezes.

when i reboot though it does say SOFTWARE ERROR (AND, this wasnt happening before yesterday. Also, this has all started to happen since i was working with Theme Park AGA!)

do you think its SWARE?

what is your power supply ?

Sounds like a bad power supply.  Are you using an A1200 or A500 supply?  Use a beefier suppply instead. My A500 overheats in about 30 minutes and causes freezing, crashes, etc.  It could also be a bad cpu on the accelerator.  That 68020 is overclocked and may be damaged as a result.  It could also be a dirty edge connector.  Try removing the card, cleaning the edge connector with isopropyl alcohol or a pencil eraser, reseat the card and test.

Switch off the computer for 10 mins. Cold Boot for your Workbench floppy disk and not your hard disk- this will boot a 'clean' environment.

Does the accelerator crash- if so it is not software.

hmmm. maybe it is the power supply. check this out:

when the power light flashes lighter and darker (when there is a problem - we all know what that looks like)... i restart but some times it will just keep on restarting - this is very hard to explain::

you know when you first restart you have different shades on your screen well they occur but then they keep on reiterating and i need to turn the PSU off and on until sometimes it will work again. apparently its a 1200 PSU it does look like one to be honest. its an old 1200 one though (not black).

Try it with your A500 heavy brick PSU

hey AKit. i will do.

but this is a little strange. i just came in from college. and i booted WITHOUTH HD1 - left it on "clicking" and no freezes! then, booted again with everything normal and again NO FREEZES. things are so inconsistent here.
