No Video Signal After Cold Boot

[JasonSix78]

Been having some issues with my monitor not getting a video signal after a hard reset. If I restart my PC from within Windows if comes right back up at POST but if I power it off it has to sit for at least 30-45 minutes before the monitor comes up with the system.

It is not a video card issue as I've changed them out.

Has anyone had this issue? Also, what signals the monitor to come on during at POST?

Try resetting your BIOS (Id pull and replace the battery).

Thanks C1! I'll give that a try. What's the lifespan of one of these batteries? I built this PC about 5 years ago.

Five years is right on the money for expected end of service life of a lithium button battery. (In fact that's pushing it if the OEM battery wasnt spanking fresh.)


Also, if using an add-on video remember the installation procedure.
With machine off - Remove any add-on card, change the battery, then boot into the BIOS and disable the onboard video, then shut machine down, install add-on video card, then reboot.

I reset the BIOS and all hell broke loose! Blue screened like crazy. lol It turned out to be a bad HDD. Even though it wasn't the battery you still helped me figure out my problem. Thanks again!

Glad that it worked out. Also, if your lithium battery was 5 years old it needed to be replaced. It was another potential issue lurking that could have caused similar symptoms at any time.
