Computer turns on then off again.

[JoshM]

Hi everyone,

 

My dad's computer random didn't work when he tried to use it today. What happens is when you turn it on, everything turns on/ starts up as normal, but it does not cast any picture then turns off again. I unplugged his HDD and plugged my SSD in and it did the same thing. I think it is the psu but I'm not 100%.

 

Thank-you in advance.

Ah, yeah. It sounds like what happened to my dad's desktop. We just ended up chuckin' it.

Did you find out the problem?

Did you find out the problem?

Nope. We thought it might've been the Motherboard but never really knew. It was 6+ years old anyway.

@JoshM, no one else seems to wanna help ya. Gee they're lazy mongrels.

Are you able to try a different PSU at all?

No image? Does the motherboard have , pci, pci-e or AGP slots? What is this pc using to produce video?

What would be your thought on what it could be? I thought Motherboard and you say possibly PSU. It could be a combination of both, IDK.

Good question. That'd be good to know.

Don't really want to take mine apart, as thats the only other psu.

It might be the graphics card.

@JoshM  Most of the time this indicates that the psu is being over loaded, bad psu or a unseated component.  Shorts can occur when a HD dies or if a fan is stuck can cant spin up.

 

What you need to do is unplug your HD power and see if the then boot.  Then unplug all you fans and see if it boots.  (just don.t run the system for more than 90 s with no fans, do not boot the os)

 

Failing that remove the ram and all pci cards. put the ram back in see if it boots.   If that does not work try one stick of ram at a time.

It's not the gpu just unplugged it and took it out, same thing occurred.

It's had a decent run then haha. We've still got an old Vista machine in our living room that was probably bought back in 2008-09 maybe (?). 3GB DDR2, AMD quad-core and a Radeon GPU, unsure of the models, but it was (and still kinda is) a pretty decent PC

Just played around with the ram, and yeah it was a dead piece of ram.

Simple fix then. shame ram prices are still really high remember the good old days 2 years ago when you could get 2x 4gb ddr 3 for £27, now its about £100.
