Sounds akin to the CPU might be overheating? or a felt in the cpu fan, I recognize that a computer will power cut if the cpu is over heating and if the fan is awful or has a short, if the fan is well, eliminate all crap from between the cpu and heatsink and affect new thermal paste, cheap and might fix it, plus it doesn’t harm to do it anyway.

Right before it started extensing out I checked CPU temp and fan speed and they were inside tolerance. Even removed the fan & block and totally cleaned out all the dust. Also reapplied thermal paste. But no cigar.

This time I think I will remove the fan & block and then rearrange the CPU. One post that I interpret said the user removed the CPU; reset it and that empty up the problem. I will possibly also try another CPU fan and observe if that works.

Yes provide that attempt, I don’t really recognize anything else to verify, the only other thing is perhaps your pc is drawing over power, try un plugging any optical drives, I had troubles in the past identical to this with desktops and it either was the ram, cpu, fan, psu or a bad optical drive.

Fine the tip is that this machine was functioning with all the similar components from the identical power plug splendidly for the last two years. No modifies to the hardware and then it just started rotating off after a pair seconds. Immediately, everything is unplugged apart from cpu/fan and video card and ram.

Fine 2 years is bounty, things do era in time, age faster with steady utilize, a pristine computer can have troubles, that’s why they contain warranties, but still after 2 years, a computers value can go from 2000 to 200, might be time for a new pc, I go flings 1 a year cause they acquire outmoded so fast no a days.

Ok I purchased a new motherboard and CPU. Put it among the stock heat sink and fan and stroked in to the container. Turned it on with the identical effect. Starts for a second then shuts off. Took the PCI Express video card out and place an older PCI video card in. It booted up and I was equal to run BartPE and do some diagnostics. All appeared ok and the machine was up for about 45 minutes. Shut it off and picked up only to have the machine over shut off after a pair seconds. I was certain it was the mobo and/or CPU but now I just have no hint. Memory sticks I alternated a pair of them in one spot and no cigar. What could be causing this...this is driving me absolutely crazy.

Before trade a new CPU and mobo, I would contain tried the less classy ideas (RAM, or GPU). You could have a terrible memory stick; although doubtful because you did test each one separately but still a slight option. You say when you place in an older PCI card rather than you’re PCI-E it ran much longer, were there any other suggestions? Did you check GPU and CPU temps? What are your system voltages and are they in sync with manufacture specifications? If you have a different PCI-E card, perhaps give it a shot.

I hear what you are proverb. I did try the RAM exchange with four sticks in all slots to no avail. What are the odds that 4 sticks of RAM have unexpectedly gone bad? I did ensure system temps and they were in the in service range. Voltages I did not look at but I was running an application that is imaginary to alert you if temperatures or voltages are out of wrack. Nothing stood out. The PCI video card I attempted is an old, old Rage128 card that doesn't even have a fan just a cooling block.

Bizarrely I did all this before I purchased the new mobo/cpu and every time I changed something out it did not decide the issue. I’m just at a loss as to what else to ensure. Could be the memory or PSU since those I am reuse. The PSU I previously bought another one with no change. The memory is good brand Crucial Ballistix. I unplugged everything from the motherboard apart from the video card, power, 1 memory stick, CPU fan and the external power switch. Still no decree. I even detached mouse, keyboard as a minimum I should obtain a post.

That is a specific window-thrower lol. I'm standing my brain annoying to believe of what could probable be doing it--you've already cleared CMOS as well as restored the mobo so I believe it is safe to rule that out. The RAM could have been overvolted by your old PSU, causing it to still be bad however doubtful.

You said you tried attractive the whole fix beyond the case (to be sure it isn't somehow grounding out or shorting due to a bad contact on the mobo/case) right?
