PC randomly turned off, what broke?

[Oliver_49]

I turned on my PC that had been left for several months not being turned on. After around 10 minutes of use it randomly turned off; it won’t turn back on again. What would cause this issue?

The PC was a Levono E50 ThinkStation Desktop.

Give it a good cleaning. A computer sitting for that long had a lot of dust settle inside and may have caused a static dust short. Pull the rear plug, open up your case and give everything a good air blast of cleaning, fans,motherboard, gpu, anywhere you can see dust get it out. Then plug it in and see if she will fire up.
