On Saturday I had two instant, no warning PC shutdowns, like the plug had been pulled. I made plans to buy a new power supply on Monday. However, it did occur to me that rather than the PSU failing, these could be thermal events. After removing dust from the fan intakes, I installed Speedfan to monitor temperatures and voltages. Two of the temperatures monitored had little flame icons next to them, the CPU was high 90's nearly boiling point!

I took the fan heatsink off, then removed the fan from the heatsink:

Oh, the horror!

Out with the hoover, highest temperature now in the 30's with the CPU at 18 degrees.

Best way to ckean out the inside of a PC is with a small paintbrush being very careful around the CPU. Vacuum's are too powerful and can damage your motherboard.

You should have that spun and made into a nice wooly pully. Smile

Dust, the number one killer of PCs. If you have wood floors they fill up in under a year and need the vacuum and brush treatment.

Now dust a minute!

Several months ago I had to replace the fan on my laptop. I had enough months of warning that I could order the fan at the computer store, which required taking pictures of the fan, as they could not be sure they ordered the right part by just looking up the model number. Of course, taking pictures with a digital camera required having a working laptop.

What's the room temperature if the CPU temp is 18?

About 17, that said I'd just switched on. CPU is currently running but stable at around 29 degrees.

My wife isn't surprised, given the state of my office. It's a while since I was last in the PC, when I fitted the Asus Geoforce graphics card a couple of years back. That got a good suck with the hoover too, too late now to tell me to use a paintbrush!

I found a mouse in my PC once. It was an old Athlon unit that doubled up as a storage heater and the mouse was dried like jerky.

Thanks Roy, been meaning to take a look at why my baiting laptop was occasionally rebooting for a while. Just downloaded Speedfan and it shows the CPU running hot (though not as hot as yours). Guess I'll be spending the weekend with a laptop in pieces.

Dude, you should dust your stuff every once in awhile.... Wink

I can't tell you how many times I've fixed that problem for people!

The good thing is that all that dust in my office wasn't breathed in by me, but sucked into a PC instead. So I'm helping keep the house clean just by having it on.
Thumbs up

Hell yeah. My dogs and cat breathe better, too! Razz

Unfortunately, my PC is having an issue with that, as is the furnace filter. Shocked

I really wish that I had kept my safari and all of my funny things. Sad

Now, putting it there, I'm rusty! Confused

Dust problems from 2007 Windypops solved that also

Fluff that was the cause!!!!!!!!!!!!!!! A good going over with the henry(vacuum cleaner) seems to have solved the problem

Seems like my video card was in the black hole of Calcutta and needed air I wondered why the fan was so loud

Good old fluffy Windypops

At least my memory ain't fading Very Happy
