• Make sure all the cards are securely inserted into the system. • Make sure that there are no physical problems with the main board or internal connections. • Disable all shadowing of expansion adapter ROMs and see if that fixes the problem. • Remove all unnecessary expansion cards (basically, everything but the video card) and see if the problem goes away. If it does, the problem is probably one of the expansion cards you removed. If not, your problem lies elsewhere. Try to isolate the problem by inserting one expansion card at a time back into the system and seeing which on e triggers the problem.
