The machine is from 2008, but it does all I need it to do. However, I fear that the fans are not what they used to be and probably need replacing. If I use it for any length of time it resets. If I leave it with the log on page after it resets, in a few hours it resets again. it makes a horrible noise when booting. I think it is the fan but I am open to suggestions.
The question is : does anyone know where I can purchase replacement fans for this old but virile computer? I really do not want to part with it. Call me silly, but it has been through a lot with me and I do not want to just discard it when it can still perform.
BTW, I am on El Capitain since that is the last OS version that I can download.
Thanks

I just did a web search for ¡°fans for Power Mac 2008¡± and got many, many hits. I¡¯d start there. The list includes mainstream sources like OWC.

If it's been used since 2008 it will have built up a lot of dust inside. Have you had a look?

First figure out which model you have, as a PowerMac won't run any thing past 10.5.8, Lion. My MacBook Pro, early 2008, will run up to El Capitan.?
Open it up and blow out the dust bunnies. Then if it is still noise, do a web search for new fans. I used iFixIt for a how to video, and purchased the fan i needed. Btw, the right and left fan on my MBP are different.

To add a little to this, printers, particularly laser printers, create a sudden power surge. Try to place them on a different circuit if possible, had if they are in the same room. Or at least not onto the same UPS or surge protector. It is not common, but large appliances like old refrigeration compressors, air compressors or even washing machines can cause a surge.
In my area, we have a 50 year old or older underground power lines, and we get many momentary outages or surges each year. My electronics, UPS and surge protectors, and appliances are starting to be affected. The power company is aware of it and supposedly has plans for new lines. I live in the second or third larges city in my state.

I would feel insecure with a $70 UPS. I guess our posts passed on the internet, because I just posted about laser printers causing surges. The momentary outage is not the problem, it is the surge that does the damage.
And UPSes and surge protectors do weaken with each event.

Barry, I don't mind be corrected, if done with a little courtesy. I did mislabel 10.5 as Lion, and not Leopard. But your reply was not well received.
I hate the names Apple uses for the Mac OS. The numbers are much easier to keep straight and even give informations beyond the general OS.
I had suggested that the OP might learn the correct description of his Mac. ?I see nothing to suggest even the form factor, or whether or not it is a desktop or laptop. Someone else assumed he had a 2008 Power Mac. Again, my mistake, I attributed the comment to the OP. A post after the one I am replying to guesses that it is a Mac Pro, but again the OP has not told us which form factor.
Why do you think it is a iMac, Barry?That it difficult to open a iMac, at the moment, has little or nothing to do with the issue, until we find out the form factor. I relayed my experiences with my MBP, early 2008, for the fan replacement issue.
But back to the OP's problem. I assume by reset means that it stops and restarts as the subject line suggests. The model or OS does not really matter. As several have suggested, their is a hardware issue relating to the power supply. Cleaning the dust out will only solve the symptoms, not the issue. The same with replacing a fan, unless the fan is also failing.
It would be nice if the OP,??ihor43us, would add some information to this thread. The thread has 14 posts in 24 hours and not a peep out of him.

Howdy. One should not plug large power-draining equipment like a laser printer into a UPS battery box. A. It's not necessary. One can print when power comes back on. B. The primary purpose of the UPS is to allow enough time to save files and shut down computer when the power goes off. Denver Dan On Fri, 25 Oct 2019 16:36:59 -0400, Barry Austern via Groups.Io wrote:

Also, it should have some surge protection, and good ones even condition the power. Randy Singer has written about that many times.

Here is a personal experience. A law office was having a problem with their Macs shutting off unexpectedly, usually all at the same time. After some sleuthing, I found that the problem was that they had a refrigerator on the floor in the break room that, when it cycled on, it caused such a sag in power in the office that their Macs just shut off. (Sometimes a large laser printer will cause the same thing to happen when you turn it on.) I purchased APC UPS's for each Mac, and I was shocked to find that the problem persisted. Then I noticed that the APC UPS's didn't include AVR. I returned them all and substituted another brand of UPS that was less expensive, but which included AVR. Problem solved. My point is that an approx. $70 UPS may be just about worthless. You have to purchase a good one that includes AVR. In my experience such UPS's usually cost over $100. Some UPS's costing over $100 don't include AVR, notably several APS brand UPS's, which is a brand that I don't recommend. I usually recommend CyberPower UPS's: CyberPower 1000AVR ($110) <> or CyberPower model selection tool: However, I DO wholeheartedly agree that everyone should have a UPS. If you experience one nasty brownout with a huge following surge in power, it will have paid for itself. I also note that folks who have USP's have Macs that tend to be remarkably trouble-free and long-lived. ___________________________________________ Randy B.

Howdy. I'll add to this. I used to visit a private girls school near Middleburg, Virginia, to deal with several Macs. The human buildings were very old with old electricity and no central A/C. The horse barns for the rich girls' own horses were nicer than the dorms or office buildings They moved a graphics design office to a different room then installed a large 110 volt AC window unit on the same circuit as the Mac, printer, scanner, etc., and every time the AC's compressor kicked on the Mac shut down. It took putting in a separate electrical circuit for the AC to solve the problem. I have several 110 volt 20 amp isolated group circuits for my computer equipment. The standard in the USA is a 110 volt 15 amp circuit. My Mac Pro (late 2013, 16 GB RAM, 512 MB SSD, two video cards), with no monitor connected and all externals disconnected, running a heavy load test, draws about 340 watts. Yes, the more RAM you have the more power the computer requires. To figure out watt demand you multiple amps times volts. 20 AMPS x 120 volts = 2,400 watts. 15 AMPS x 120 volts = 1,800 watts. A good recommendation is to load the circuit to about 80% of the maximum. (Most European countries use 220 volt power. In the US, most houses have both 110 and 220 volt with the 220 volt being used for heavy consumption devices like electric clothes dryers, electric ranges, furnaces, but circuits for lights, lamps, standard wall outlets, using 110 volts.) And yes, I have several UPS battery boxes. Northern Virginia is one of the more heavily forested urban areas and we see the tail end of hurricanes, electrical storms, and a LOT of new construction in this area. A typical Brother laser print could draw up to 500 watts when printing and maybe 50 watts in standby mode. Devices with electric motors and heating equipment draw a lot of power.
