Computer doesn't make it to POST, but everything is running.?

Question

I've tried searching all the questions on here, but I recently had to replace my motherboard due to a failure, and I replaced it with an identical model. The PSU is brand new, and the Hard Drive has been tested on another computer and works fine, but I can't get anything when I turn the computer on. All the fans, cooling system, and CD-ROM drive come on, but nothing ever displays on the screen. I've tried reseating the video card and RAM with no success. HOWEVER, ONE time I was able to get the BIOS screen to come up with my Windows Vista CD in the drive, but I didn't have the keyboard plugged in to bring it to setup, and I haven't been able to get it again. Help?

Answer 2

Replace the CMOS battery. If you bought it online at Newegg or some similar site, they sometimes ship with a dead battery. Otherwise, make sure that your powersource is still functioning properly...if the fan isn't blowing, you have a problem.

Don't boot with the "Vista" CD in the CD drive...try to boot normally first.

Basically, it'll be start and restart for you. Unplug everything and try to start. BIOS shows up - great. Plug in the hard drive, restart - Windows starts - great...

Step by step! Replacing the mobo is a pain in the ***. Boot to the CD that contains the mobo's drivers first.

Answer 3

plug in just the basics: power supply, motherboard a stick of RAM (if you several & still have problems try swapping them), video card (if you have on-board, use that instead), keyboard (although POST will go on even without one). now everything should work but if not then I suspect if not the ram then it can only mean the mobo although i had one pc where the power supply is causing the problem.

Answer 4

Try this.....one stick of ram, video card, cpu, and HDD. if it still won't post, you're back to RMAing the board again.
