I am building a new comp for my brother and having some trouble. The mobo is an ECS 661GX-M 1.0B SIS 661GX 775. CPU is Intel CD 2.26GHz 478. I have a 512MB PQI DDR400 RAM chip. I am using a know good HD, CD/DVD Drive, and PSU. The case is a CompUSA model bought new. I installed every thing on MOBO according to User's guide and turned on. The HD light just stays on, but does not sound like it is "working". The CD drive will not open and light never comes on. The heatsink fan for CPU is running. When I disconnect cables form MOBO to HD and CD Drive they both start operating as they should. HD starts spinning and CD drive light is active and drawer will open. Is this a DOA MOBO, CPU, or both??? The CPU, MOBO, RAM, and Heatsink/Fan combo were all purchased from Newegg.com. I have never had a problem with anything else I have bought from them, and I have never dealt with a new MOBO before just upgrades. Thanks for any help you can provide!!!
