    Dell - Fan ramps up but no boot

    Have an interesting one. Reception phone up & they have an incredibly noisy fan. Go down and the PC isn't booting but when switched on the fan builds up to full speed. No error lights and after getting it up to the office I have found sometimes it does come on but I can't find a correlation between coming on and anything I have done or conditions. I have reseated everything, tried one memory module or the other & upgraded the BIOS.

    Any ideas?

    It sounds like it isn't POSTing, but power clearly is going through the system. If possible, remove any non essential components. If the PC works after you've moved it, chances are either a component is loose or possibly the motherboard itself is shorting out on the case. It could also be a cold boot problem if the room is particularly cool.

    Reset CMOS. Nothing.

    Removed just about everything, even HD, FD, CD, all mem modules. There are no extra cards. The stupid thing is sometimes it comes on fine, I can access the BIOS, everything appears great, boot up, get on. Turn teh machine off & restart & either straight off or after one more boot it fails again. Our room is fairly cold but I wouldn't say where it came from is.

    What model is it? we have had GX260's and GX280's do it. turns out in every case we have had it was the motherboard. look at the Capacitors at the siliver bit at the ends, on the MB one will look like it has pushed up.

    Yep it is a gx280 but check the caps and all seem fine. No obvious popping. Would it still be PSU even with power getting though ok (the power test light is fine) & sometimes it starting ok?

    I would say the probability is it's the motherboard from what you're describing, but by all means, swap components with another system.

    PSU still my bet.

    I had a GX240 that would sometimes start and sometimes not the other day.

    Changed the psu and it ran fine, I hooked up a standard ATX psu you to test it before buying a replacement.

    Ta for the suggestion. I'll swap with another we have in but I don't think it will be the same as it's not just not starting but doing this whole fan thing as well so power is there. I'm starting to think more it must be a mobo Ohh well, time to order another.

    Currently can't get it booted to even select that, I'll try & have a look. I imagine if I can get to teh point then it will say everything is fine.

    have you tried reseating the cpu and applying new thermal paste I have stacks of gx280s like this all have different problems but do the same super fast fan spinning trick! there was a motherboard recall on this model so if yours isn't too old you might be able to get them out to relplace it even if you are out of warrenty?

    I'm watching this thread with interest, as I'm just about to give up on the same model/problem. Tried all the suggestions above some time ago with no joy. The fan now always fires up at hoover levels, rapidly rising to harrier jump jet .

    The machine is currently on the "one day" pile, but I'd be interested to know how much a new mobo costs if you go down that route.

    The unit is from 04 so maybe ok. I'll look for the recall, never heard about it! I do know that they all start jet fast for a second to start with but this is a real slow start & then building up to continuous jet speed added with no diag lights & just an orange power light. I'll keep this updated if I find anything & with what we do.
