Help emachine T3418 wont boot,if it does,it only shows the screen for boot/bios section,which it wont let me choose either one. I changed the power cord but that didn't help,I cant boot from emachine recovery disc,or windows xp disk. I hear the fans running,it just will NOT do anything? I removed the cmos battery, reinserted and still nothing. I don't know what to do next, I'm pretty good at working on my pc's but i'm lost at this one? Anyone at all, please help me out????
