Amiga blizzard/apollo 040 problems

[JACK98]

Recently i took my A1200 out of storage and wanted to try and use the blizzard 030 card,but for some ungodly reason i could never get it going right*hence reason it was left in storage!*,it would be fine for few seconds,the crash,or do a continous reset,now i have suspicion could it be the following?-

card ram faulty
my motherboard revision,its an 1D1 with the timing fix
faulty card
Heating issues?

my A1200 is in its case,i have an goliath/A500 psu to spare,so if anyone could help to solve this age old mystery i be greatful.
