My A1200 freezes all the time

[walkero]

Hello guys,
I have a problem with my amiga1200. Recently I bought
the 3.1 rom module to update my old 3.0 module. I used to have a partition with OS3.9. When I changed the roms I decided to format this partition. So I did a format with FFS and then changed my old 3.0 roms to 3.1.

I tried to boot from my WB3.1 boot disk so that I could install OS3.9 from my cd. When WB showed up the first freeze appeared. After many retries I managed to install 3.1 to the hd.

After a cold reboot I tried to boot from my hard disk so that I could install my powerflyer and my cdrom, to install OS3.9. Unfortunately, the freezes from times to times never stopped. After many tries I managed to install OS3.9 but now after the reboot I can't install anything because when the install comes up everything freezes. The CGX drivers are not installed yet because my system freezes at the start of the installer. Alse the setpatch command at the startup-sequence is "SETPATCH QUIET NOROMUPDATES scsi.device"

My hardware is an Amiga1200 with BVISION, blizzardPPC 603/175/040/25 with 96MBram and powerflyer, 6GB HD and 350W PSU. The motherboard is 1v1d.

I have to mention that before the update everything worked just fine with no problems at all.

Thanks for your time guys.

Thanks my friend for your fast reply. I think that the heat is not a problem because the freaze of my computer comes after a few minutes of work. Even though the case is all open and two coolers working in full time.

Thanks also for the link. I'm gonna have a look there now.

thanks guys for your help!
Xand: I tried that but nothing changed. Also I forgot to mention that when I boot from my hd partition, an error occures which is saying that MDH2: partition crashed and to reboot.
I removed and the memory simms one by one but nothing changed.
I checked the SETPATCH and the Installer version and these are the latest.
The one thing that I have to try is to raise more the  powerflyer because it is real close to the BVision.

bloodline: Unfortunately yes...I believe that it is a matter of overheating.

Sumner7: Nice jokes my friend...

Lately I found out that the ata3.driver v6.1 of the
powerflyer freezes my amiga and returns an error:

"MDH2
Program failed (error #80000004)
Wait for disk activity to finish"
But nothing happens. Nor the mouse moves.

If I deactivate the driver. I see only the first two
devices but my amiga works fine...
Is this a compatibility problem of the ROM 3.1 with
the powerflyer?

If anyone has a clue about this, please help me....
