Something I can't understand...

Is it different in terms of hardware? Is it more difficult to repair a Dell or let's say an HP and other pre-built systems?

These systems are only used by companies, schools and other government corporations. Never seen a home user using a dell.

The Dell GX 270 motherboard has had a lot of problems with the capacitors. They received a whole bad batch during manufacture. The problem usually is similar to what you have described. Visually check the capacitors for swelling and/or leaking. If they are bad the motherboard will need replacement.

Aside from the capacitors which I have been go bad on those GX 270/280 it can still be the power supply. You have to remember that the power supply tested can only test if the power supply turns on and give you its reading. It can't tell you how it would function under load.

I have had this overclocking message at bios level before on computers that were using Asus motherboards and have definitely not been overclocked. On each occasion the message was caused by a faulty fan on the graphics card that would work intermittently. I replace the cards in both cases and it solved the problem. It's funny the only time I have seen an overclocking message is with Asus motherboards.

Just remember that the GX270 has a totally different motherboard from the GX280.

That's interesting - I've been using Asus boards for quite some time now (and had that problem from time to time). However, I've been using a passively cooled graphics card.
