M5800 shuts down just after loading into windows

jwarden

I have a M5800 that turns on just fine, and loads Windows Vista with no issues.  I have not really used this computer maybe less than 200 hours total running time, but now have a need for it.  About a minute or so after sitting at the Windows desktop, it shuts down as if the plug was pulled out.  It also takes a while for me to be able to restart it, but the same thing happens again.

 

I did take the side case off, and blew out any dust in there, checked for loose connections and all that.  Everything looks good.  When I restarted it again with the side case off, I noticed that once it shuts down, the large CPU fan will run at a lower setting. 

 

I assume it's thinking it overheated, but I can't imagine that since all fans work at full power up until it shuts down, and it simply hasn't done much real work outside of starting up in order to generate a lot of heat. 

 

Ideas?

Hi jwarden!

 

It sounds like your PC's power supply may have an issue. They are cheap enough to buy these days, and try to go for a similar (or greater) wattage to the one that's already there.

 

One other thing - has the graphics card been changed from the original? If so, it may be too powerful for your existing power supply.

 

Either way, it looks as if a new one is needed. You can always see if you can "borrow" a supply from someone and try it in your PC, then that way, you'll know for sure!
