Windows 10: PC randomly shuts down.

Hi,

I have a dell xps 8300 running windows 10 pro v1511 which was clean installed a few weeks ago.

Sometimes when I cold boot my computer the computer shuts down unexpectedly on the windows 10 splash screen. I have unplugged everything from my PSU apart from my windows hard drive and graphics card and still get the random shutdowns. I've also removed and cleaned the heatsink/fan and CPU and applied new thermal paste but problem is still there.

I'm not getting any BSOD's or memory dumps if it helps

Anyone have any ideas?

Thanks
Kamal

PC Randomly shuts down

Nope. The system logs do not contain any personal information.

They even do not even contain the make and model of the PC

 

PC Randomly shuts down

I had windows 8.1 home, and my current version is windows 10, 1709

 

What kind of Power Supply are you using? Watts

 

I'm using the standard dell 460watt PSU that came with the system

I have 2 hard drives, 1 Bluray drive, 1 DVD drive and a AMD Radeon 7870 graphics card plugged in.

 

Did you added the graphics card to it, yes?

 

Yes I did about 8 months ago.

 

That could be where the problem is. It just might be the graphic card is using more power than what your supply can provide. Have you try not using the card and just use the internal?

 

My PC doesn't have on board graphics. I originally had a amd radeon 5450 in there before it died.

 

If you had this Radeon card for 8 months and this just started happening then probably not due to wattage demand, although always seems hard to find out the requirements of wattage and what is also important with Graphics cards Amperage for AMD cards. I roughly see 450-500W PSU with close to maybe 40amps on 12v rail.

Since it happens at the very beginning does not seem like overheating going on. RAM can be another cause ,but will sometimes shutdown and restart over and over. What else was added or changed in this system ? With PSU never get exact wattage needed always go a bit more then needed. Hard drive and optical drives not going to use a lot, but then matters how many pieces of hardware you have.

 

It has a VGA port, yes? I don't think 460 power supply is enough. But to be sure I would try using just the VGA port, remove the Graphic card and don't go nuts with playing games. The whole point is to see if you're still having issues and if you don't then you can zero in on the power supply / graphic card

 

The only other thing I changed was upgrading to Windows 10 from 8.1

 

Ok, this happens only on a cold boot. Again unless PSU has an issue now or recently had added more hardware then might say not enough wattage, but had same hardware for months. So if the PSU there is another issue with it then this. Sure applied thermal paste correctly ? Since do not have integrated graphics be kind of hard to test if it is the card unless you had another graphics card, said something about a dead one tho. When PC does stay on i would use HWMonitor look at the temps and voltage of the PSU, can post a screen capture of it.

Ones pointed out on PSU voltage seem a bit low, temps on System seem o.k.. Did not go down to the Graphics card. When this shuts down randomly it never restarts right away or does it do it while using the PC ?
