After Thunderstorm my dad's computer had NO POWER, NO LED's. I opened the case looked for anything obvious (burned components etc.) Plugged in and shorted Start switch pins on motherboard, NOTHING. Pulled PSU, smelled hot, so I opened it up. Sure enough Capacitor looked like a PARTY FAVOR and circut board burned. Advised dad of the outcome. First the PSU is BESTEC Model# ATX-250-12E Rev P-6. Does the Rev P-6 in the Model# indicate a proprietary power supply?? I installed another power supply, that had an A/C switch on back turned it on PSU fan,CPU fan,P/S LED,all ON. NO BOOT UP, SHORTED P/S pins on motherboard, NOTHING. I was informed PSU was prop. searched fourms,Some say yes, some say no. IS Rev P-6 an indicator? THANKS FOR ANY and ALL HELP, MRBONES2U

All the major wires are the same as a standard ATX PS in the main connector - the only difference is there is an extra small voltage sense wire in position 20 in that Bestec model.
If you hold your cursor over the main connector here, all the major wires are tyhe same. In the notes below that it tells you of two smaller sense wires - the first one is in all 20 position standard ATX main connectors.

It is extremely likely you can use a standard ATX PS in place of that model.

Your problem is not that the wiring is proprietary - it's that emachines has a reputation for using these el-cheapo Bestec power supplies that are much likely to fail and much more likely than average to fry something else when they fail. Your computer is not starting up because something else has been fried - in many cases we have heard of it's the mboard that is fried, and replacing it will probably get the computer running fine again.

If you like I could look up which mboard your model uses and see if I can find some links to used mboards for your model, and you can decide from that whether you want to put any more money into this computer.

If you have another computer, you can try the cards in that, or try the hard drive connected as slave on either IDE or as master on the secondary IDE, or try cd drives and the floppy drive.

Usually the ram and cpu are okay.

Testing the ram in another mboard, or testing other ram in this mboard, will not necessarily work - the ram has to be compatible with the other mboard.
See response 5 in this for some info about ram compatibilty, and some places where you can find out what will work in your mboard for sure:

The Bestec is a standard ATX power supply. They're stock in many Emachine, compaq and HP computers. They don't seem to have much stamina as I've had to replace a few.

It's possible the PSU you replaced it with is proprietary. Some of the older Dell power supplies were that way. But most likely whatever fried the power supply also damaged the motherboard.

Thank you very much for the quick response, 1st time I've asked a question in a forum, most times browsing does the trick. As for looking up the moboard, I'll look it up and get my Dad playing poker in no time. Once again Thank You, MRBONES2U

T-2245

www.emachines.com has only some downloads and some specs for your mboard - it doesn't tell you which mboard brand and model the mboard is:

A very good alternate third party site:

According to this

T2245 has has a Trigem Imperial-GLVE mboard

Unofficial info here:

No manual for GLVE in the Downloads, but the manual for GLV is very similar

According to that page, the same mbooard is used in:

NOTE that the Trigem mboards can have many different brand name bios versions. I advise you to buy one with an emachines bios version. A mboard with a different brand's bios version will work fine, but you may have problems if you ever need to restore the original emachines software if the restore looks for an emachines bios version and doesn't find one.
You could flash the bios to an emachines version using the downloads and info on the emachines-upgraders site, or use bios updates if any are available on the www.emachines.com for your model, but flashing a bios is always a risk and you can end up with a mboard that will not boot after you flash.

Yeah, at least in those black and silver cases, often HP, compaq and emachines will use the same motherboards. The only difference being the bios is branded with their own logo. Recently I put an HP board in an emachine. As I recall, even though it was an exact match except for the branding, the existing XP installation didn't accept it as the same board. I think I tried forcing a emachine bios update but it wasn't accepted. It's also likely the restore disks won't work if the brand is different.
