Compaq Proliant 1600: Error 1611 - I/O Fan failure detected

After a power failure system made shutdown when log-on. OS Windows NT server version 4.0 service pack 6.1.
Opened case and removed the top cover. Found the fan on top front (towards door) not working. It is a 12VDC 0.4 Amper fan.
Replaced it with an equivalent since same not available in market; it is working but still system resets when logging-on. Any idea what is going on?
Thank you so much!

I think it can be a defective memory module. Can you remove the modules and test one by one to see if the system hangs?

Will try, thank you. Meantime I tried several things, nothing worked. Remains the SW1 dip switched on I/O board (6 dip switches in total; perhaps the last switch 6 in relation to the NVRAM might work?
Do u have any idea?
Thank you.
