I'm usually pretty decent at figuring out my computer problems but with this one I'm puzzled. Over the past couple of weeks I've been having trouble staring my PC. I'd press the button in from to turn on the computer, all the lights came on, fan was going but nothing else. Didn't hear the CD ROM/DVD ROM drives spinning and no post. Just the fans. I tried to hold down the power button to shut it down but nothing happened, it just idled like that. Then i proceeded to hit the "reset" button below it, still nothing. I had to resort to hitting the power supply switch. After doing that, letting it sit for a few seconds and restarting the computer, all was fine. At least I thought it was. BIOS loaded, log in screen showed up but after logging in the screen was black. I was able to hit Ctrl+Alt+Delete and bring up the task manager. All of my programs INCLUDING explorer were running. I then manually shut down explorer.exe and manually restarted it. Explorer loaded with no problems except for icons of running programs missing in the taskbar. I have been shutting the switch on the power supply every time after shutdown but it doesn't always work. Today the CD/DVD ROMs spun but I got no POST and no BIOS on the screen. I have updated all of my video card drivers and have attempted to update my driver for my motherboard (which ASUS has since had new versions of) but when I try to update the motherboard drivers, the DOS shows up and them disappears without installing. A few weeks ago I had updating my version of DivX and it sent my computer I little haywire. The audio wasn't working and startup was taking forever. I proceeded to remove DivX as well as change my Anti-Virus from AntiVir to AVG. Also recently I keep getting messages that say "New Network Found" with an IP address (that I can't remember right now) from Zone Alarm, mostly when my modem isn't turned on. My computer isn't hooked up to any other computers and my printer was off. I have also noticed that one of my system processes is running at +100,000. When I run Belarc Advisor I get this under "Network Map": 22.214.171.124 System Ool-44c37005, ool-44c37005.dyn.optonline.net, Dell The physical IP is 00:1a:a0:a0:17:9f Here's some more info on my PC that I got using Belarc Advisor: *Operating System Windows XP Home Edition Service Pack 3 (build 2600) *Processor 3.20 gigahertz AMD Athlon 64 X2 Dual Core 128 kilobyte primary memory cache 2048 kilobyte secondary memory cache 64-bit ready Multi-core (2 total) Not hyper-threaded *Main Circuit Board Board: ASUSTeK Computer INC.
