Question about HP Pavillion a818n Desktop PC (Refurb) Pentium 515(2.93Ghz) 512MB 160GB (PS453AAR)

3 Answers

No power all of a sudden i went to turn on the machine and there is no power going in. it was working fine the day before. all the connections are tight and the line to the wall is live. so the red and green light are out or not on. the fan is not on. i took the case off and nothing jumps out. could the power supply simply fail overnight?

A voltage spike can trip the power supply into "protection" to prevent damaging the things connected to it. If this is the case, disconnecting from the wall outlet for a couple of minutes may reset the protection circuit, therefore returning normal op. If that doesn't clear it up, you ay need a new power supply.

    If this has the 2.93 Ghz processor, half-gig of ram, and 160GB hard drive the heading says, I would think it worth a new power supply. Some HP units however take a special power supply drsigned to fit the box. Be sure to do your research.

Probably the power supply. Yes, they can fail that quick. You can try swapping out the cable just to make sure and make sure the voltage selector is set properly to 120VAC.

    Unplug the old one, remove it, take to computer repair shop and see if they have a used one that will work. That's what I did. The guy gave me a used one free.

Nikon d40x suddenly stopped working- won't turn on- was working fine and when I connected it to laptop to download, it turned on , then suddenly went blank.


Do you get the 'push shutter button again' or 'turn off and on again ' message? If so the motor in the SQ unit that charges the shutter and moves the mirror up and down has failed. A very very common problem. The part is on constant back order at Nikon, and good luck getting it anyway as Nikon is going to stop selling parts to anyone in just a few weeks.

Power off


Double check your battery connections & make sure they are all clean & tight, and don't forget to check other end of ground, not just positive. be sure to take a good look at the ends for wire deteriorating at connections. I have seen batteries short out like that, so battery is certainly a possibility, but eliminate the other posibilities first/too. You might find a ground strap ( flat braided strap) going from passenger side frame area, to engine, make sure that's in good shape & connected to a good ground too.

Dishwasher stopped working..!!..!! please help


Hi crystal245,

I'm Harvey the Master Plumber.

Your problem is: GE Nautilus Dishwasher suddenly stopped working. NOTHING!! it was fine one day then went kaput the next. I checked the plug in and the circuit breaker but still NOTHING

I run into this often. Ends up being loose, broken or burnt ellectrical connection in d/w junction box most of the time. It's under the d/w behind the kick plate on the right or center. Turn the power off first and remove the wire nuts. Replace wire nuts and/or repair wire ends as nessessary. Beyond that you're looking at a bad control board or failed connection in the unit.

Feel free contact me again!
