Hi forum goers, I'm having an infuriating time with my desktop PC. I tried to install some new RAM and a new second harddrive, got everything plugged in, and the computer wouldn't boot. So I backtracked, replaced the RAM, replaced the hard drive, and the computer still won't boot! The power turns on, with the fans running, the drives spinning, the LEDs going, but the monitor can't find a connection. I've double checked all the connections, tried all combinations of new RAM and old with new hard drive and old, and have also tried with no second drive. The OS is on the primary drive. Anyone have any suggestions as to what to do? Something that might be significant. When I unplug my monitor from my PC, it says "check display cable" but when my computer is off or when I try to turn it on now there is just a blinking green light in the front bottom. Some Specs in case they're important: Old RAM: 512MB New RAM: 2x1GB Video Card: Radeon 9800 Primary HD: 300GB IDE Old secondary HD: 40GB IDE New secondary HD: 500GB SATA 7200RPM Thanks for your help! P.S. Sorry for the typo in the heading!
