Connect hard drive to know working computer and see if it is recognized in the bios. If not then the hard drive logic board is fubar. If working, perform diagnostics on it. If you replace the cable that might do it. Bad connection?

I would have gone with a descent 600 watt Psu, however the Gpu is low profile, what's it like on onbaord Graphics, if it's the same there could be hardware issues.. Check Sata Cable to Hdd...also start pulling a few sticks of Ram out boot up one stick at a time...also use Speccy at www.piriform.com check the heat these small towers if not vented correctly will get hot!, a better heatsink and extra fan extraction will cure that, expect 35 Degrees for Intel, 45 Degrees plus Amd ish only a vivid guide as all differ slightly maxing out at 60 degrees ish.. hope this helps

maybe the power supply

Hi. you have to use DDR 2 RAM with 800 mhz . you`re Manuel say`s maximum is 4GB. maybe a BIOS-Update can help to use more than this 4 GB. otherwise you need a new Motherboard to fix this. lg Gue.

press the power button.

press the power button

most likely the power supply is dying. best bet is take it to a service center and get it checked.

What is the problem?

You are right. It is the resolution that was set too high. This can be easily fixed in Windows by booting into Safe Mode and lowering it.

You can go to the control panel and adjust the power settings there. It usually looks like a battery icon.

Possible that PC is hanging up as there is fault on the OS (operating system) or a virus in the OS. Also it is possible that the backup battery (CMOS) has low voltage or the memory card is a suspect. In this case you need to check the voltage and also try and swap a memory card. Sometimes the memory card connections can be faulty either on the card or on the slot. Cleaning the slot and card must be done before you try a replacement. If the PC boots and fails then the hard disc can have bad sectors or is corrupt. However if there is no result the motherboard also can be suspected. In this case you might need the help of proper tools and equipment support to do a chip level service.

Hi! Welcome to Fixya.
Have you try booting to BIOS and wait if it will still shutdown? Going to BIOS requires you to press F1 or DEL (or other keys depending on manufacturer) If it will not then try Safe Mode (F8) and check if it will still shutdown. If the system will still not turn off, then you may try re-installing Windows or run stress test that will utilize the system and force it to shutdown. If it did then it may be the motherboard or other parts that needs to be replaced. If you are lucky (that computer did not shutdown) and able to re-install windows that the end of your problem. but if you are still having the same problem then possibly your computers motherboard may have a leaked capacitor or some sort.

Hope this instruction is a great help. Thank you for contacting Fixya. Bye for now.

DO NOT OPEN A POWER SUPPLY!!!!

NEVER!

Inside an SMPS, (Switched Mode Power Supply), are Electrolytic Capacitors.

(Radial. The bottom capacitor in the photo)

Electrolytic Capacitors slowly build up a charge, then release it all at once.
You can compare it to a large swimming pool being filled up with a garden hose, and then one wall of the pool being taken down all at once.

At the bottom, of the Radial (Style) Aluminum Electrolytic Capacitor shown in the above photo link, are two leads.
One is Positive, the other is Negative.

Touch your finger/s to the terminals on the bottom of one of these babies, and the shock can be BAD to FATAL!

If your fingers touch, and complete a circuit that one, or more capacitors are in, the shock can be BAD to FATAL!

Don't open that power supply!

Besides, a fuse goes out All At Once.
There is no work a little bit, then turn off.
It just goes Poof!
(The fusible element inside burns into two separate pieces)

Now,

"You press the power button, and it doesn't turn on all the time"

As has been suggested, I also concur that you have a bad power supply.

But you could also have a bad Power On switch, located inside that plastic Power On button.

This is an example of a Power On switch, that I have found fits a lot of computers,

http://www.directron.com/atxswitch.html

I'd like you to get this switch, and install it.
From there the diagnosis will go to the Power Supply.

Also would like you to make sure the ram memory is seated tight, and the Processor fan is spinning, and looks to be spinning at the right speed.

If the fan spins a few times, and stops, then spins a few times, you know the fan has a bad bearing. Replace.

If it looks to be spinning too slowly also, you'll know it

Be sure to follow anti-static precautions before you reach inside your computer, and the computer is unplugged from power.
If you do not know what anti-static precautions are, I'll be glad to tell you. Simply state so in a Comment.

As for the Power Supply test, you need either a multimeter, or a power supply tester.

An inexpensive multimeter, that will work just fine for this application, ranges from $6 to $12. The Voltages are only 3.3 Volts, 5 Volts, and 12 Volts. (DC)
Two C cell flashlight batteries are 3 Volts. (DC)

Your computer power supply puts out three main Voltages, as stated above.
A) 3.3 Volts (3 point 3)
B) 5 Volts
C) 12 Volts

Orange insulated wires are 3.3 Volts
Red wires are 5 Volts
Yellow wires are 12 Volts

ANY Black insulated wire is a Ground wire.

This is DC Voltage.
There is a Positive, and a Negative.

The Positive (Red) probe lead of the multimeter touches a power wire. (3.3, 5, or 12)

The Negative (Black) probe lead touches ANY Ground wire. (Black)

IF, the 12 Volt power rail shows 11 to 13 Volts, the diagnosis indicates the Power Supply to be good.
(However read on)

IF the 12 Volt power rail shows 11 Volts, or less, the Power Supply is bad.

This is an example of a power supply tester,

The battery is on the motherboard, but it'll be a 3V battery - a CR2032. You can find these at most drug stores or a battery store. It'll look like a shiny silver coin, approximately the size of a quarter.

If the computer is slow to boot up, there are several factors to take into account. The RAM could be going bad. The hard drive may be going bad. There could just simply be too much "junk" on the computer and it may just need defragmented and cleaned out.
