Well, this problem is similar to the other guy who created the thread "computer start up question". But our problems had differences so I decided to start this new thread to minimize confusion. Before this wait-till-the-end-of-the-world-before-PC-boots-up event happened, the PC kept on restarting and sometimes not even finishing start up. I ran Memtest and found out that the memory was broken so I replaced it. After replacing the memory, I was able to use it normally for sometime. Then there was this day when it took a long time for the PC to boot. I thought it was nothing until it worsened. Now I have that PC on for almost an hour and still no response. PC fans are turning, power LED is lighted up, LAN card LED lights up when connected, CD drive has no power(it won't open). When I remove the IDE cable from the CD drive, the drive recieves power. What can be the problem?
