Hi all,
I have an assembled PC built from 2013 with
Motherboard: Gigabyte B75M-D3H
and PSU: Cooler Master GX 450 W
The configuration is old now, as you can see.
The 3.0 USB ports had already stopped working long ago when Windows 10 was installed on the system, because there were no USB 3.0 Windows 10 drivers available officially from the Gigabyte site for this motherboard, and I don't think Windows 10 generic drivers are working.
A few months ago, I noticed that the keyboard and mouse connected at the USB 2.0 ports of the back panel of the motherboard suddenly stopped working. I tried the other USB ports at the back, and on connecting to one of them, I got the message in Windows that there was extra power surge at that port. I do not remember the exact message. After that, I connected both the keyboard and mouse to the front panel USB 2.0 ports which are still working.
Recently, a few days ago, I tried to check the back ports again to see that power surge message, but now the back ports are all dead... no activity at all on connecting to any of them.
Is this is a motherboard problem, or is it a PSU problem? Is the motherboard going dead, or did that damage come from the PSU?
Rest of the PC continues to work well, except for another thing.
I had APC BR600CI-IN UPS connected until last year to the PC. I had its battery replaced once already and it was working well. Last year during the lockdown, one morning I turned on the UPS and it just started to trip repeatedly. I immediately disconnected the UPS, and kept it aside. Since then, I am running the PC from a power strip.
I could not get the UPS repaired during lockdown. I am still not comfortable with a technician visiting the house to repair the UPS. Also, he will most probably want to connect the UPS to the PC again, for testing the load and to see how is it tripping? I do not want to take that risk. Also, they will charge 350/- just for visiting, apart from the repair charges, which I find a bit steep. I am not well these days, and so I cannot take the UPS for repair personally at the APC service center... so that will have to wait.
OK, so that aside, I recently noticed that my PC was shut off a couple of times when I came to check on it. I generally keep the PC running throughout the day. In our area, power goes off randomly anytime for a few minutes, so I thought that power must have gone down, and maybe I did not notice.
But just yesterday, I noticed that the power point for the power chord connected to the CPU on the power strip was making sparking noises. The noise increased, and spark happened and PC just turned off. Today, I replaced the power chord, but the same thing is happening again... sparking noise. Is this a power strip issue, or somehow there is back surge from the PSU? Can that happen? Or, is PSU having a problem?
I should mention that the same sparking kind of noise used to occur from the UPS too, when it was connected to the PC. I thought that the noise was coming from the UPS and I should get it checked soon. Alas, I could not get it checked in time.
Maybe that noise was from the PSU power chord? Not sure.
I won't be able to get the UPS repaired anytime soon, so for the while, if there are any suggestions for a good, reliable, power strip or extension boards with minimum 4 points, which I can purchase from Amazon, please provide.
Should mention that since I noticed the sparking from the power chord, I also noticed that connection from the network interface from the motherboard to the router was turning off randomly, and causing internet disruption. Again, a PSU issue or Mobo? The connection disrupts for a while until I take out the network cable and put it back in again. Works fine after that.
Also please tell if the PSU is going bad or the mobo?
I haven't been able to clean my PC also since a very long time now, so the dust accumulated inside might also be causing problems. I used to clean my PC very regularly before, but lately I have turned lazy or just keep postponing it.
I think it might be time to go for a new PC assembly. Will ask for suggestions in the forum, if I decide to go that route.
