Hp pavilion slimline shut itself off and will not come back on.

Sounds like a power supply problem. Usually this occurs when
doing work that involves a lot of memory, and progressively gets worse.
It has something to do with the crowbar circuit that shuts the power supply whets overloaded; sometimes a trigger-happy SCR.
Life is a lot better if you use one of those Ebay power supply testers with an LCD display, but these testers don't draw enough current to trigger a potentially bad crowbar.
Best solution I can think of is purchase another ATX power supply 350w or more with the same dimensions. Pay attention to the lenght of the replacement ps to see if it's too long (front to back) to fit in your computer.
Hope this helps.

TG-3018 Tiger power supply for NCR POS PC system...keeps shutting off within 5 minutes of starting.

Is it overheating, and shutting itself down, to prevent heat-related damage?
Check that any fans inside the unit are still working.
Replace it.

At start up, no signal on monitor, computer shuts down.

Most computer testing facilities will test your current power supply for free. A replacement is very inexpensive to replace. Bestbuy, MicroCenter, small computer shops and buy replacement from, Just make sure you have the correct information for your replacement. The model number on the power supply would be your best bet in most cases. Good luck and have a great day. I buy power supplies as low as $15 dollars Generic

Replacing the Power Supply DEPENDING on the power needed? you might have to settle for a slower, weaker performing video card. Make sure you check the video card power supply specs needed.
Chances are you will max WATT at about 300WATTs less then what you'd need to power a gaming video card. OR you could do as I'd do.
Remove everything and place it all in a standard tower case - install a 650WATT power supply in to the new mid/full size case and BAM solution found.. Have fun and a great day to ya.

Power will not stay on

PSUs don't last forever, 3 / 4 years they are dead or going.
use a digital muti-metre to test the Molex connections
should be 12volts, 5volts, and 3.5 volts for motherboard conns.

or with E.S.D. kit Replace the PSU, very quick and easy job.

15 minute job.

Hope this helps

Pc no start.........

You might have a bad power supply. If you have a voltmeter, check the voltage of the standby power supply. This voltage is present even if the system is off, plugged in. It powers a small portion of the logic circuit. It should measure within a couple of tenths of exactly +5 volts. If it is low, or high, this will prevent turn-on. The purple wire of the 24 pin connector is what carries this to the motherboard. The color coding layout is found at If by chance this voltage is OK, then check the full on voltages also. Repair of the defective supply is probably by replacement of one or more small electrolytic capacitors in the appropriate circuit, especially if you are technically savvy. Capacitors are available through several suppliers; Digi-Key supplyies Panasonic FC series which are suitable for switching power supplies. Or, you may just replace the whole unit.
