Motherboard and PSU strange behaviour

About two weeks ago, I began installing the windows 10 anniversary update. After the first half of installation I shut my PC down.

The next day, I booted the PC up again, but it got stuck in a boot loop. I turned the PC off unplugged it and waited a while. I then turned it back on, it finished installing the update and it worked normally.

But an hour later, it randomly rebooted whilst I was doing some work on word.

I realised it was the PSU, and I borrowed one from another unused PC I had. It works fine for now.

I found this strange because the PSU never gave any indication of instability. No excessive noise, buzzing or heat. I opened it up and there are no bulging cap's, it clean too no dust.

I was thinking that the motherboard could have caused the PSU to go bad. It has always acted strangely. Not long after I bought it, I lost the ability upgrade the BIOS and chipset driver's. About a year ago the onboard graphics died and a week ago two of the rear USB ports exipbited odd behaviour, losing hardware control of my external sound card (volume constantly maxed on 4 out of 6 ports).


My question is, could the mother board have caused the PSU to go bad?

If so, should I upgrade the motherboard and processor now?

Or wait to see if it is stable?

Or potentially sacrifice another PSU?


Current system specs:
Intel Pentium G640 (sandy bridge)
Fujitsu socket 1155 motherboard (can remember the model number)
8gb corsair XMS3 RAM
Seagate 500gb HDD
Old blown PSU XFX TS 450w (based on seasonic design)
Current PSU FSP 300w (can't remember the model number it's 80plus bronze though)



 
Solution
If the old psu works fine in a different pc does that mean that another part is the culprit here,maybe the motherboard as you suspect.

Hey Vic40 sorry I accidentally voted down your post. I was looking for the reply button, to quote what you said.

I have not tried it on another PC. I will try doing that.

In regards to the warranty, I'm fairly sure it has expired. Even if it has not, it would cost me a lot of money in postage to send it in for RMA.

So if it works on another board, what could that mean?

I probably should ditch that mother board shouldn't I.

I need to find a board I don't care much About, to test it out.

Ok I triee the PSU out on a different board. It exhibits the same behaviour.

When I looked inside again, I saw that one of the components mounted to one of the heatsinks looks loose.

I will investigate further, but for now it's safe to conclude that the PSU is to blame.

I think I'll Save the good seasonic unit I have on order for a new build around Christmas this year.

With that old psu going bad it maybe did some damage to the motherboard as well.
Did you try a clear cmos to see if that wil help in someway?

That new build doesn't sound bad looking at what you have. By then AMD Zen might be out and do you have some nice options to choose from.

Sorry it's taken a while, I've been really busy.

I'm interested in Zen, but i doubt I can wait until the scheduled release in early 2017.

Im considering building a new PC around the Intel core I5 4440/4460 series chips. I can get a used I5 at a reasonable price 110-135. A good mother board costs about another 100 USD and I can reuse RAM and drives plus my new PSU.

I know it's a 2 year old platform, but look at the I5 2500k, it's old and great. I know many people overclocked theirs for longevity. But the other related I5s of the period still hold their own in gaming.

I don't see the skylake I5 prices dropping much for Christmas. Couple that with the fact I won't be able to reuse my DDR3 and it could exceed my 330 USD budget.

Does anyone have a reasonably priced skylake build in mind? 330 USD max budget for processor RAM and motherboard. I've been looking at the I3 6100, can it at least try try match the performance of the older I5 system I have in mind?

I feel as though building a system around the AMD FX 6300 would be a waste. From what I've read the I3 6100 is better. If Zen comes out in time for Christmas I'll give the AMD a chance.

But considering that I'm only a casual gamer. I'm focused on productivity and I want day to day speed. What would you guys recommend?

PS: Yes I have a graphics card (R7 250 GDDR5) I will update it later, because at the moment, it games great at 720p and I'm happy with my 720p monitor. Everything must be bought through Amazon, because I'm outside mainland America.
