Hello all. Can anyone help? My 64 bit Mesh machine (mesh computer nero 9950hd) switches off about 10 sec. after switching on. Can anyone suggest a way forward to identify the cause of this problem... Any help would be much appreciated.
Richard.
10 Sec sounds like over heating.
Open up the case and see if the fan is spinning, flick it with your fingers if it isn't, etc.
Hoover the heat sink if it looks dirty.
Caveat not that I know anything about it.
I meant CPU fan, not case fan.
Do the fans run?
That's about 10 years old, and there may be hardware issues with the motherboard or PSU.
The usual way to deal with this is to try each of these steps in order:
Clean all the dust out of the case. Run the PC with the side cover off - are all the fans running? Reseat all the RAM, and push all the plugs on the board in properly. Check the motherboard for blown caps. Replace the thermal paste on the CPU. Replace the CMOS battery + reset the CMOS Disconnect as much as possible from the motherboard, eg the hard disks, USB devices, DVDROM, graphics card (if there's onboard graphics), leave minimum RAM - try to get down to the minimum configuration that will POST. Swap in a known-good PSU.
When you've done that please let us know the results.
Ten seconds is a little short in my view. Some kind of psu fault? Brian
I have to say that I had an amd 64 bit machine running windows7 then8 then
10, one day it started to do this. The psu had gone but took the motherboard with it. Salvaged still intact ram and an hd and dvd, chucked the rest away. Brian
At a guess it is so loaded up with gaming hardware the PSU cant cope
Grateful thanks to everyone... I had to be away for awhile but now I can respond to all the points mentioned... Both CPU and Case fans are running okay, there was some, but not much, dust in the CPU heatsink but all that has been cleaned when removing the processor. The motherboard appears to be physically 'sound' with no blown caps. I have run the machine with minimum load on the PSU and with covers removed but still the same delinquent behaviour... The actual delay is circa 12/16 seconds. I had a similar problem about six years ago when the machine simply shut down without warning after one to four hours and the solution at that time was to replace the PSU. So my strategy now is to obtain a known good PSU as GB suggests so I'll replace the 500W version with a 600W new from eBay?? I will keep everyone apprised.
Thanks again and kindest to regards all... Richard.
Get a decent PSU.
I think that is a reaopsnable way to proceed.
PSUs will shuit down on overcurrent or overtemperature and the way they measure both is via components that can age.
If it still shows this behavior after a new PSU is installed ny guess would ne that smomethhing is loading it up, and here its a question of unplugging peripherals and any boards until the pronblem goes away or if it doesn't, new motherbaord time
Really doing a binary chop on the hardware is the simplest way to id a device thats sucking power. Removing teh disks for example should result in a machine that boots to te bios. If it stays up, try adding disks back one by one - you get the idea.
A wet afternoon and plenty of coffee is helpful
I had a PC that shut down about 6s after start - it was the 'Turbo' button permanently made, so the PSU was shut down after the set time for power-down on pressing that button or tha Start button. I just isolated it as I never used it. Your time is too long for that, so possibly the PSU. I always fit a good Seasonic from mid-range or above. This one is 400W - way OTT and runs at about 100W even of starting, but it never gets hot or overloaded. Idling is a bit less than 10% of PSU. It wasn't possible to get both the quality that I wanted and a 200W one.
Recently I have had the power button sticking down, so the machine turns on, but soon trys to reset and can't move on from there.

WD40!
Any suggestions or recommendations for a DECENT PSU??
Or
The fact you are having to replace a 4 year old generic PSU suggests that buying a decent brand may be a good idea. Also, you may not need such a powerful one in a decent brand. What have you got loaded into the machine that makes you think you need a 600w PSU?
I agree with buying Seasonic/FPS. Good makes.
In general serious gaming video cards are power eaters
Oh Dear... The case has changed!! The switch off delay has today changed to just 3 seconds after switch on! And, I have obtained a PSU which is now in the machine but THE SYMPTOMS ARE THE SAME :-( So, it appears that the mobo is sending a 'shut down' signal to the PSU almost immediately (3s) after switch on, I suspect that some (small?) component on the mobo has failed but it is nigh on impossible to identify which component. I have used a large magnifier to inspect every component on the mobo but to no avail, nothing looks untoward! So it is looking like a new mobo or new machine here.
