OK, when all my coursework has been done and handed in, I will swap over the PSUs and see if thats the problem... hopefully, I am getting tired of having to share my computer with my fiancee already!

Right, swapped over my Dell PSU into the emachines... didn't make any difference. Put it back into the Dell, and that one works again thank God! What do I try now? Thanks for your help!

A small number of Dell PSs are wired in a proprietary way - if you have such a PS, it will not work for a mboard designed to use a standard PS, which is probably the case for your EMachines computer, and you may damage both the PS and the other mboard. The colors of each of the wires at the 20 positions in the main connector from the PS must be the same at the same positions, and some positions must have two wires that are the same. In other cases I've heard of with EMachines computers, it was the mboard that was damaged by the power supply failing, and they were able to get the computer going again by replacing both power supply and mboard, but there's no guarantee that's what's wrong with your computer - if you can take the cpu someplace and have it tested, that's advisable. Usually the ram is not damaged by the power supply failing, but floppy drives, cd drives, and cards in the slots might be - you can test all of the latter in another computer, but if the ram doesn't work in another mboard, that doesn't necessarily prove it's bad - it must be compatible with the other mboard - in the worst cases the computer will not boot if it is incompatible with the other mboard - in not so bad cases it will work but not be recognized as its proper size. If you supply the exact model of your EMachines computer, I can probably find out which mboard you have, and you can use that info to search for a replacement mboard if you're so inclined.

By the way, the hard drive is very unlikely to be damaged physically by the power supply failing, but it might have some corrupted data on it. Here's how to check your hard drive. See the latter part of response 1 in this: http://www.computing.net/windows95/... If the hard drive is okay and you want to use it in another computer without losing the data on it, see the latter part of this to get an idea of what's involved: http://www.computing.net/hardware/w...

The drives all seem fine, I wired it all together to get the data off onto my Dell, so it's ok from that point of view... My Dell PSU looks the same, same ratings on it, and checked wire colours etc... it did power the fan and lcds etc, but no boot as before. I think I might have to just ditch it - we can't really afford a whole new motherboard etc. Might have to wait for another day... At least we still have another PC! It is an eMachines 610, with an AMD Athlon Sempron. Thanks a lot!

your mboard is MS-6777 which is usually also listed as a MSI K7N2GM-L I found this by searching for: K7N2GM-L motherboard: This one probably has a MSI bios - if it does you can flash it with a Emachines bios version if you must (see below for the update) - One here: 14.99 so far - 5 days left - bid on it! http://cgi.ebay.com/MSI-K7N2G-L-SOC... .....

Thank's a alot. I'm in the UK, think the one on eBay might only ship in the US... I'll check around though. How did you find out that that was the right mobo? Thanks!

You may have the best chances of eventually finding an exact replcement mboard with an emachines bios version on ebay UK, since yours is a UK system model. But one with the MSI bios version is the same mboard, plus or minus the firewire. "How did you find out that that was the right mobo?" It all started out when I was researching Trigem mboards used in other brand name computers. I discovered Trigem mboards are used in many name brand computers in their el-cheapo models - HP and Compaq for sure, probably others, and often the same mboards are also used in emachines systems. When you search for info about those Trigem mboards, you often get hits about them on third party sites about emachines systems. Apparently emachines has never been very good about revealing a lot of info about their systems and what actual mboards are in them, and the info they do have about older systems eventually disappears from their web sites - because of that there are various third party sites that saw a need to retain the info about older systems and to provide more info about the systems in general. Many of the emachines systems have Trigem mboards, made by a major Korean manufacturer. In fact, many emachines systems are actually Trigem systems in emachines branded cases (they may be the same cases as Trigem uses) with an English bios on the mboard, or whatever language where they are sold, and software in a suitable language. The info for Trigem mboards disappearing is especially frustrating because the parent Trigem web site probably has support for current and older mboards but it's only in Korean! Having found these third party sites about emachines systems, I found they also have info about what mboards they have in them, including those that don't use Trigem mboards. In this case, the make and model of mboard is obvious when you look at the mboard. In the case of Trigem mboards, it isn't as obvious. NOTE that they are probably more choices on the web as to where to get a different bios version of the emachines bios than just the one on the emachines-upgraders site, if you happen to get a mboard with a MSI bios and you want to use an emachines bios version. MSI makes mboard versions with or without a socket that the bios chip is installed in - in this case going by the pictures the bios chip (see the large yellow dot in the pictures of the mboard) is soldered directly to the mboard and cannot be removed and replaced, at least not without a lot of expertise, so in this case if you were to flash the bios and the bios chip physically failed, it would not be worth the money and trouble to replace the bios chip. These cheap flash chips can only be flashed an unpredictable small number of times.
