Motherboard on it's way out?

Klo · 23 Jul 2016 at 20:09

Hi,

My computer has an issue where it freezes on the motherboard splash screen. I can't enter the bios, and it seems there isn't any power going to the mouse or the keyboard.

After doing a hard restart (I need to turn the power on and off again), it sometimes boots into Windows, but after a little while the computer freezes, my mouse and keyboard appear to lose power again and I have to hard shutdown.

The motherboard/processor is 9 years old this year, so I guess it's allowed to finally die, but I was wondering if there is a way to check it actually is my motherboard and not something else (power supply?)

Specs

Q6600
Gigabyte P35C-DS3R
6gb RAM
AMD 7870
Samsung Evo 850 1tb
Corsair HX650

Any ideas would be appreciated!

Have you reset the bios? maybe tried replacing the bios battery all together?

I'm unable to reset the bios as I can't get into it. I haven't replaced the CMOS battery but I wouldn't have thought it would stop the system from booting would it? I just thought it might lose the time and date when that stops working.

When the cpu fails usually you cant boot anything so it looks like yout motherboard. I would suggest checking you ram try to boot with a single stick.

You reset a bios by removing the CMOS battery

for like 10 seconds.

Well I built is 8/9 years ago. Basically I've been away for 2 months, fired it up after coming back and the problems started. I don't think anyone has touched it in that time.

USB ports dying or been faulty is known to cause system wide sporadic issues. Try (if you don't already) switching your mouse and keyboard to ps2 connections and remove all other usb devices and see if this solves anything. I've had a similar issue happen to me on a p55 board, back then I thought is was crazy that the usb ports would be the cause of these issue but clearly I was wrong.

Even if this does turn out to be the case it's still not good news as you'll likely want to have working usb ports, but at least it might give you a work-around in the meantime. If you eventually get into the BIOS you can even disable the usb ports.
