    Please check and see:

    1. What colour is the light on the power button, does it stay on or flash?

    2. This computer has a set of diagnostic lights (likely marker A,B,C,D) which of these are on if any?

    Is the fan running now?

  • Anonymous Mar 25, 2014

    About 2 months ago my fan started running very high in the afternoon or if I was playing a game online. Suddenly this morning I turn the unit on and its running extremely slow. The fan still comes on but not at the high speed it had been doing. I can not go online at all. If I go to open an application I can go cook and eat lunch before the app is available. I have had this computer for about 3 years, is it worth fixing, or even fixable?

I had same problem today and i tested my machine and solved the problem at last.
the problem is the thermal value that your mainboard sets for your cpu.
please replace the mb.
ps: before this process,i tried almost everything . cpu fan , memory , cpu , cables ,case ... everything. but the problem is on your mb.

Dell opitiplex 280 is not giving display. first of all his fan speed to much high and then after 4 or 5 day its display disappeared. its just picking now power and fan also start with high noise and...


OK, I use GX280s as home servers and ran into a similar problem with one of them...

The problem may be serious and not worth fixing (motherboard).

Turn power on
Fan(s) come on full power, sounds like a jet engine, or eventually gets that loud.

See if you power light has gone amber.

You get nothing on the screen, no Dell splash screen/post, nothing.

This is what I posted a while back concerning the above. Obviously I cannot bee 100% certain as I do not have your box in front of me. This a known issue.

--------

See if the power light goes amber after power up. I had (have - still siting in my basement) one that did same. Power up, fans go full blast . Power light goes and stays amber. This is USUALLY caused by bad capacitors on the mother board. Known GX280 problem going back. If you look on the motherboard, the capacitors should have flat tops and not leaking. If the are rounded or leaking, the MB has probably gone bad. Bottom line this is usually a defective motherboard. Mine was a bad caps issue, you issue could be different, but it does sound like the motherboard.

You can google "gx280 solid amber light loud fan" and see the issues. Here is one link.

I just replaced one of my old 280s with a dual core Dell Precision 390 workstation for about $118, and that included shipping, off of ebay.

My pc gx280 is not display fan and pclight on fan is high noise


Could be a possible videocard issue.
Try connecting a working videocard in one of the expansion ports.

A high fan noise could also mean a failing power supply. If you have a spare power supply I would also suggest installing the spare one

Same problem... orange power light, fan starts slow and builds up to very high speed.
I removed my video card and SIMMs --> it beeped on boot and the fan did not speed up.
Put one SIMM back in --> booted fine, pressed F2 to view BIOS. Memory reported fine.
Put all SIMMs back in --> all fine now.
