Pc wont turn on

[angelus2141x]

Hi all,

        Thanks in advance for your help. Last night I was using my pc as normal. I had been using it throughout the day playing World of Warships or KSP and watching youtube in the background. Suddenly last night after being on for say about 12 hours (not always playing games in that time) it just shut off completely. Not unusual I thought Id recently had an issues with my cpu cooler dying and had to replace it and that had resulted in the pc turning itself off when it got too hot. So i went to turn it back on as thats what i did in the past and I got nothing. It wont even turn on (fans dont even start up).

 

Heres what I know. The mobo and the gpu are all still getting power as LED on mobo powerswitch is on (although it wont turn on using this either) and the gpu led lights are on. The on off switch on the psu still lights up so I think power is working but not sure. The only significant change I can see is in the ram. I have some geil black dragon ddr3 1866mhz (down clocked to 1600 mhz for my mobo) that has red LEDs built in. Now those LEDs are not lighting up. Im pretty sure from memory that these LEDS were on even when the pc wasnt. Now these were the die hard burn in test edition so are unlikely to fail but yes I know unlikely and wont are two very different things and this pc is now 3 years old and theyve been in use most that time.

 

So id like your input here. Do you think its a ram issue or maybe a psu issue or maybe something I havent considered entirely.

 

thanks

Just check if u plugged in the display connector

I would think it's the ram, as the computer won't boot without it.

Try using a single slot and see whether it starts up.

just to clarify this is not a new build it was a working build for some time. Also the pc wont turn on at all no fan start up or anything meaning the display connector isnt an issue.

thanks for the reply have already tried this which reminds me was using 2x4gb sticks should of said that earlier tried reconfiguring by switching positions of sticks and switching to one stick and when that individual stick didnt work I tried the other stick on its own and still nothing and both sticks no longer have working LEDS

it could be failing RAM, as Xenift suggests, try one each stick in all the slots and see if that works.

What are the specs?

ha, your reply landed as I posted mine. With this checked it makes it tougher to find out whats going on. Does your board have on-board graphics? Try unplugging everything from the mobo and then see if it posts at least, then start adding things until the problem kicks in. IF its not even starting with next to nothing running off the mobo, then its most likely to be a cpu or mobo issue

MSI GD65  gaming mobo 

Core I5 3570K

8gb DDR3 ram (2x4gb)

GTX 560 ti (no old jokes pls)

120gb SSD primary

1tb HDD secondary

700w psu (yes I know its overkill but its what I had available)

 

Also I have now individually taken each stick and put it into each slot from right to left and attempted to turn on each time and nothing.

the problems could result from previous heat issues when your CPU was overheating .... really hope its not this though

yeah me too cos i really cant afford a new cpu right now. so ive tried booting with the sata cables/usb3/fan connector all disconnected. Now when you say try booting with things disconneced for my gpu can i just take out the 2 six pin or do you mean remove the card entirel?

 

Also just checked the power cable for cpu and doesnt seem to be the issue either as (well at least the cable isnt)

[angelus2141x]

so heres how I see my options

 

buy a new psu and see if its actually psu thats not delivering enough power (maybe its just delivering enough for the LEDs)

 

buy new ram and see if that is the problem (im leaning in this option because leds arent on but then again loosing 2 sticks of ram simultaneously seems unlikely)

 

if one of these two fixes doesnt work then only option left would be an issue with cpu. But the temps its running at since new cooler seem fine.

 

im just trying to figure which option is most likely psu not delivering enough power ( it is an old crappy ezcool thing) or both sticks of ram being bust.

 

someone needs to make a quick plug and play hardware issue detector. Would make life so much easier. lol

 remove the card completely and use the onboard graphics. The fewer things plugged in can help you pinpoint the issue easily.

 

good luck
