Computer Does not turn on

[Akshajb]

I installed my new RX480 Gaming X by msi on my PC. It worked fine for a day. Yesterday I had paused a game and had gone out for 6 hours. By the time i was back the system was off.

When i press the power button now, it does not turn on. 
my setup

motherboard : ASUS H10 Chipset

Processor - Pentium g3240

Graphics- rx480

PSU- 450w included with my 9 year old Case by zebronics

Cooler- Bequiet! pure rock slim

 

Is my PSU dead?

 

Thank you

[MrMcMuffinJr]

first of all, is it plugged in?

second, try to reset cmos.

We can't tell you that, you have given us very little to go on. Strip down your system to the bare essentials (just a CPU, RAM, motherboard, and PSU). see if that works. then start adding stuff until something screws up. that's the problem. 

if it screws up with only the basic things, one of them is the problem, but you'll need extra components or more advanced troubleshooting I'm too lazy to describe

It is plugged in. I shall try the CMOS reset.

to test psu, unplug everything and on the mobo pwr connector, bridge the green wire to any black wire and see if the fan spins up. if not it is dead.

make sure EVERY psu cable is unplugged, that includes sata.

I hate to be the ass that asks since many people think it's irrelevant, but we're you grounded properly when installing the GPU?

 

Is the GPU still seated properly?

 

Also, MrMcMuffins post is absolutely correct. Unless you have a legitimate PSU tester, that's the only way I know if for testing the PSU, other than putting into a different MB.

Luckily i have an AMD mobo and processor, but no RAM( DDR2 ). Shall i connect it to that and check?

Yes, connect anyways. You should fail to post, but it should still power on. Your testing to make sure it'll even turn the system on.

Well. I connected, but it did not turn on. The motherboard light turned on , the moment i switched the PSU on, but the power button did not turn any component on.

Did the PSU fan spin? The lights came on, so I'm hopefully, but just incase:

I connected, and it did not spin , i hope the thickness of the wire used for connecting isn't important.

No, it isn't. As for the board and CPU you're testing with, try bridging the power switch header manually. just use something metallic (and conductive, of course) to bride the positive and negative pins. The issue may be your power switch...

I checked with a screwdriver. Whenever the psu is connected and Switched on , an led on the board lights up. But no fans spinning after i tried shorting the power pins.

A PSU problem would be my first guess. The PSU's included with cases 9 years ago were never very good in the first place.

 

But, before you replace it, try unplugging the power to the PSU (unplug the power cable) or turn the power switch off, if it has one. Leave it for 10 seconds or more, and then plug the power back in. Some power supplies have protection circuits that have to be reset by removing the power.

 

If that doesn't work, try borrowing a power supply to see if it will then start up. The temporary test PSU can be almost anything, since you just need to see if it will start up - that is, it can even be only 200watts since the system will only be at "idle" for the test. (The only concern would be that the test PSU has a 24-pin main power connector and a 4 or 8-pin ATX power connector. If it doesn't have a PCIe power connector for the Graphics card, remove the graphics card for the test.)

1. Tried unplugging and replugging.

2. Tried Cmos reset.
3. Weird thing, if the psu is dead, how does the mobo light turn on? nothing else happens.no fans spinning .
4. I do not have anyone nearby with a spare PSU for me to check.

It m have enough juice to turn lights on, but not enough to turn other things on. Or that board just won't turn on without RAM inserted. Have you tried manually connecting the two pins as MrMcMuffiJr pointed out? PSU alone,  or MB or anything else connected.

 

If you live near a PC shop, they might have a 24 pin PSU tester.

Yes i tried that and no , nothing happened.

The PSU has a couple of independent current sources. The "standby" source, which lights the mobo LED, may be working, but some other source might not be. (+12, +5, +3.3)

 

In retrospect, this may also be caused by some component having died and causing a "short" (or overcurrent) that is shutting down the supply.

Unplug everything from the PSU except the 24-pin and ATX power connectors. That is, unplug the power from all the drives, and remove the graphics card.

Then try to start the computer. If it starts, then try reconnecting the drives, etc, to try to find what part is bad. (Use the IGP while the graphics card is unplugged.)

 

After that, it comes down to the CPU, motherboard or PSU being the problem.

Then your PSU is toast. Time fir a new one and hope all of the components survived.

I replaced my PSU with an Antec VP500PC , and everything worked. I gamed on it for 4 hours straight. After that , I had left the system on for an hour and gone out. It was switched off, and is not switching on anymore.

Please Help

[RustyRotary]

i would check for shorts like things not being fully plugged in and such

Please help.

this seems to be a software problem, try to sniff around in the bois/uefi

Take out the RX 480 and see if the problem goes away. If it does, RMA the 480.
