I have been upgrading an old Compaq Presario SR5130NX. I'm new to the computer scene, and decided to switch the PSU to 230V, just to see what would happen. It exploded. That's what happened. I installed a new PSU, and now, whenever I turn on the PC, there is an error message saying "CPU fan has failed" and the PC shuts down automatically before I can access the set up, or bios. My case is currently open however, and I can see that the fan is working so I think the motherboard got messed up, and I'm afraid this could have also damaged my graphics card and memory. My motherboard is a m2n68-la (ivy) and here are the product specifications: http://h10025.www1.hp.com/ewfrf/wc/...&product=3436820&tmp_track_link=ot_search#N96 Can anyone tell me what's going on? Can this be fixed, or should I just get a new motherboard and start from scratch? If I'm posting this in the wrong section, please point me in the right direction.
