I urgently need help on this problem. My PC won't boot. Instead it first displays the Windows XP splash screen and then shows a message stating, "We apologize.....but Windows did not start successfully....". Then it gives me the option to start under various alternative states: safe mode, use of last successful settings, etc. I tried each of those, but I only was able to boot in Safe mode with constant beeps. My System • Asus P4P800E Deluxe motherboard (circa 5/2004) • 3 GB RAM (3 X 1GB Kingston sticks) • Windows XP Pro (auto updated) • AMI Bios • Socket 478, P4 CPU • Antec TruePower Quattro 850 PSU I have 2 hard drives, • C: & D: (partitioned) – 250 GB total • E: - 300GB and 2 CD/DVD drives: • Sony CD/DVD player (master) • Pioneer CD/DVD burner (slave) In addition I have the following PCI cards: • Nvidia GeForce 7800 Graphics • Sound Blaster X-Fi sound • Hauppauge TV tuner BEEP Alarm sounded When my system last worked "properly" I was having problems with my DVD burner. I replaced it with the current Pioneer. When I reassembled everything, I got a steady, continuous beep, beep, beep, beep, beep, beep, etc. I went to my other system and researched beep alarms and determined that I had a power problem. I then rechecked all my power supply connections. Windows would not boot After I rechecked all my power connections, and after finding that the beeps continued, I attempted some trouble-shooting (perhaps right down through my foot!). I detached all of the CD, floppy and DVD drives and powered up. At that point Windows would not boot. I reattached the same drives, checked the power connections, powered up again, and still no success. BEEPs continued in Safe Mode I was able to reboot in Safe mode, but, when I did, the beeps started up again. Now, I'm lost and need help.
