e-machines T3958 PSU dead???

So my sis-in-law says she's got some version of the dreaded AV virus. Popups saying she needs to buy, can't even open a browser window, etc. (I've had damn near everyone I know come to me w/ this virus. It's a doozie, fortunately not damaging)

Anywhoo.......bro-in-law unplugs it from their house, brings it down to me & when I go to plug it in, there's nothin'. Zip/zilch/nada!! I put my desktop back on & powers up fine. Put theirs back on & nothin'!!

I pulled the side & there's definitely a light on the mobo when I plug it in, but hitting the power button just won't power it up.

PSU dead???
 
double check the connection from the power switch to mobo. maybe it got loose during transportation. You can also try to power up by shorting the power on pins. Otherwise, it could also be a symptom of bad mobo.
 
Could easily be a PSU. Thats at least easy to test. Just unplug, and hang a test PSU off to the side.

As said above you need to test the button too. If not, could be mobo.
That's and old-ish emachine.
 
Best part is that I literally just put in a PSU for somebody at work whose computer tossed the PSU and I had that sucker sittin' for about 6 months!!! LITERALLY!!!

Fix that guy's computer which puts me down to zero extra PSU's and what happens????......family member has an issue.

Of course, they weren't expecting the PSU prob but, oh well. (They were using the computer literally an hour before so I suspect PSU) I've noticed that occasionally (especially for computers that just sit) just unplugging/replugging a PSU is a liability in itself. Sometimes they go for no reason at all.
 
I know I'm late on this but sometimes when power goes out here mine will not come back on UNLESS I turn off switch on power supply itself THEN hit power button on case for a couple of seconds. Turn switch back on PS then hit power button on case and it comes back up. If I don't do this it will not come on as in no fans no nothing but mobo does show power on led.
 
That was actually one of the first places I looked thinking that when it didn't come on, maybe BIL had thought enough to switch it off before giving it to me........but alas.......there's literally NO switch on the back. There's the 115V/220V selector but that's it and even that is basically isolated. It's a sticker that's punched revealing which voltage it is, but basically discouraging any accidental switching to the wrong voltage.

Good guess though. I've seen PSU's at funny like that before. Too bad this one didn't at least have one I could play with just to rule it out.

For this model I would bet it is the motherboard that has crapped the bed. They are notorious for this behaviour.

And I do believe, sir, that you are now correct!!

I put a new PSU in there & it acts exactly the same!!! 🙁

Not good!! This truly sucks!!!

I couldn't find anywhere where the T3958 (or even T-series per se) likes to toss motherboards.

And all this just for moving the friggin' thing. As it was sitting, just hours before I got it, it was working just fine.

I work on these crappy e-machines, Gateways etc all the time and 9 out of 10 that have the symptoms you described are Motherboard problems. There is the rare one that is just the PSU, but ... Just my personal experience. I wouldn't give you 3 cents or every e-machine ever made.
 
pcgeek11 is right. I bought a refurb one for my wife dirt cheap. Had an MSI motherboard in it so I figured it couldn't be all bad. Died after three years. Fortunately, it's a standard micro ATX form factor, so a cheap, new mobo fixed her up real good.

Motherboard...dead, psu...dead, Niedermeyer dead
 
Well, put in new PSU *AND* new mobo......however, I can't believe this but the sucker STILL won't turn on. Not even a whisper of a single fan!!!

🙁

I'm down to just mobo, CPU and ram and still can't get a blip (except for the green LED on the mobo).

This one truly has me baffled!!! I'm at a total loss on this one!!!!
 
1. Clear the CMOS and give it another go.
2. Try booting with no RAM and see if it beeps code. If yes the CPU is likely fine.
3. Try jumping the power switch header pins momentary on the motherboard.
 
Run all of this OUTSIDE of the case too... on a non-conductive surface. It could be that the old motherboard uses one more stand off than the new one and you're shorting it somewhere inside the case.

Tried all that & more!!! Switched CPU & ram (plus w/o ram) w/ my Dell 4600c & still nothin'. Put the e-machines CPU & ram in the Dell just to see if all parts are ok and they work just fine.

Now I'm reeeeally at a loss.

I'm almost tempted to try a 3rd PSU just because I don't trust anything. The PSU does turn on the green LED on the mobo and the new PSU l/O switch on the back does turn the LED on and off but I'm not sure if I can trust that *that* means there's power going thru the board.

OH.....and replacement mobo is the exact same mobo (literally) so all standoffs, headers, etc. are exactly the same.
