Anyone have these: Fujitsu Esprimo E3521 desktops?

We have a classroom of 30 of these and a few others dotted around. They seem to have an intermittent fault that is driving us crazy. When you power on the PC it is meant to whirl up the fan for a second and then boot the PC as normal, but intermittently it gets stuck on the fan and then PC goes no further and nothing shows up on the screen. Sometimes by the time we've brought it back to the office it is working again and other times not. When it persists we've contacted Fujitsu support and they've come out and swapped the MB's out (about 5 or 6 now). The problem seemed to go away after the board change, but now we've got one whirling again that has had it's board changed, so Fujitsu have now taken the whole unit away for investigation. I have a nagging feeling though that it will come back with no fault found and Fujitsu are not admitting to this being a common fault they know about. The boards have the latest bios on them before anyone mentions.

Has anyone else experienced this fault?

We have these (and others in the range). It is a common problem and for us the answer is to take out the ram and reseat it. That usually cures it.

We have 66 in two Suites and experience the exact same problem, most times after an engineer has been out and changed motherboard/power supply, it has been fine except a couple which have re-offended, the engineer that came out to us stated that it is a common fault.

Thanks guys, I didn't think it would be a simple explanation but at least I know other people have the same problem. We have around a year and a halfs worth of warranty left so we'll just have to get Fujitsu to repair them each time. It's not good for the teachers when they have large classes and they can't guarantee the PC's will boot. I'm not sure we'll buy fujitsu again.
