PC Problem: Fans and PSU turning on, but no PC case lights (Power) or Signal to monitor!!! - Page 2

So he took out the graphics card while the PSU was plugged in and switched on? That must of shorted the motherboard then. 99% sure it's the motherboard. I've seen motherboards die from doing this.

Well a good replacement motherboard is the P45 chipset ones such as Asus P5K / P5Q series.

Cool thanks.

Just to make it easier I ordered the same motherboard, hopefully it is the mobo and when I get it and install it everything works wink.gif

Can someone with vast PC Knowledge enlighten me?

I JUST installed my New motherboard, (exact same MSI G35 mATX LGA775 board) to replace the old, possibly "fried" board.

I install, and boot up - SAME Issue, SAME message, "No signal to monitor detected".

Keep in mind I'm running a VGA cable straight onto the mobo onboard GFX for simplicity.

SO at this point I am really kind of sad, because I just paid $$ and ordered the mobo, and spent some time putting it together. Thought now it was going to be more of a hassle and it maybe the CPU or RAM......

BUT I decided ONE LAST TRY.

I turned the PSU off and held the POWER BUTTON on the PC case (silverstone temjin) for about 30sec-1min.

I then switched the Power supply online, and pressed the power button .

VOILA! The damn thing turned on and the monitor turned on! It said "PC Overclock settings have failed!!!!"

So I loaded the default settings and booted to desktop..


I am just so CONFUSED as to how the hell that fixed the problem. The only reason I even did it is because I read it on google a few days ago and it was some what of a hail mary.

Now, I am puzzled and deeply curious that if I had done the same thing with the old motherboard, would the PC have started??? Though, the only difference is that , with that old mobo , I didn't even have the PC case lights , lighting up.

But when I booted up with this new mobo, the PC case lit up blue, so I thought I had made some progress.

I think you should test the old motherboard and try that with the same steps.

Haha, my brother is saying he tried the same thing with the old motherboard but I don't know if I believe him. He said he held the power button with PSU off & on 2 times and nothing changed.

I will say, when I installed this new mobo, even though I still got the "NO SIGNAL error", the blue LED case lights attached to the MOBO did LIGHT up , which they did NOT do on the old mobo.

The computer was also louder, which I think was the HDD booting up and such, when basically the fans only turned on with the old mobo
