I have a system that I can't seem to figure out. After a recent windows update, it won't boot. It seems to keep posting, then turning off, and on, and off, and on. I'll see the HP logo appear for a second or so, then a "VGA No Signal", then the HP logo. This loops indefinitely. From my understanding this started after a recent windows update. I've tried a hard drive component test, as well as a memory through the HP diagnostics. I also did a full system extensive diagnostic test. I have reseated the RAM, changed monitors/ cables, and tried launching windows from different drive. The issue persists. The screen stays up while in BIOs/Diagnostics. Any idea of what the issue could be? Tech support so far has been about as helpful as ever.
