Today I went to go turn on my computer and I noticed that the CD-ROM drive and Hard Drive light stayed lit. I have no video. I powered it down and turn it back on thinking it would work the 2nd time around, still the same problem. I also notice that the HD is not making the noise it always does when it boots up. Next I took out the memory one by one just to see if anything would change. Still the CD-ROM and HD are still lit up. At this point I'm thinking it's my motherboard, but not sure. Does anyone have any ideas on what it could be?
