New problems with Blizzard 040 & Amiga 1200

[Gavilan]

Hi!! im having new problems with another machine...
This one is a Escom 1200 (bought it from Software Hut a couple of years ago in mint condition) and a Blizzard 1240.
The machine used to work perfect, until one day. Suddenly, after i connected to a 1942 monitor, the machine freezed, refused to boot again
I took out the accelerator card, the machine boots but it takes up to 5 minutes! To load WB!!!
The configuration is this: Amiga 1200, Blizzard 1240 with 16 megas, HD 2 gigas, Eide buffered interface and an external scandoubler which was used hooked to a 14´´ pc monitor until i got the 1942.

Any ideas?

Cheers!
Sebastian

Well, the machine is NOT towered. I had it working with no problems for more than 1 year. Suddenly, after the episode i nebtuibed, i powered on and just black screen. If i take the accelerator out of the machine, the machine will rund, but taking up to 5 minutes to load wb!! Thats strange and i dont know why it takes soooo long! Its an Escom 1200, and the only things i have are the Eide 4 buffered interface, and the hdd. Of course im using the original PSU...
