Ok, it looks like tomorrow I will be pulling this particular machine apart and rebuilding. It's a 4 year old machine that I use for video and music in my bedroom. Specs are as follows: AMD 6100+ Biostar Tforce 550SE mobo Asus ATI 1650 with stock fanless cooler Turtle Beach Santa Cruz Sound Card 2x Samsung 1 TB HDD 4x1 GB Wintec Ampx DDR 800 Win XP SP3 So today I went to boot up and it got to the initial XP loading screen. Normally the screen would flicker and then load the desktop. Now the screen flickers and the monitor senses "No Signal" but I can still hear hard drive access. I can boot into safe mode no problem. I tried restoring a backup image from about a month ago and same problem. The bootable recovery media showed no problems. Next step, decided I'd just install Win7 since I had planned on doing that soon anyway. Looks like it was installing fine... on reboot, it hung during the loading screen and same "No Signal" issue. So now I decide to see what happens with Linux. I was going to install PinGuyOS. Booted off the CD and decided to let's try Live first. Same thing... It would start loading and then "No Signal." I'm assuming this is a video card issue. I've had zero issues with this card previously... no artifacts or anything but I also don't play games. I have had a few intermittent blue screens with always different codes but checkdisk has always solved this. I ran diagnostics on the hard drives and they were fine and memtest86 was also fine. I will swap out with another video card tomorrow and see what happens but was wondering if anyone else had any good ideas?
