PC turns on and off

[anas115]

My pc turns on and immediately gets off.. I thought it is power supply problem so I tried changing smps and removing battery. Tried removing rams and checked wires. Nothing worked. Please help..
Lesson learned : never buy anything from relatives.
My built is I5 4440 2.8, DDR3 RAM 4+4, graphic card R7 250 1gb ddr5..
Tried removing graphics card..

That is not full system specs and that is not full model name of the PSU. However I can tell already that it is a crap PSU.

Full system specs goes like

CPU: I5-4440
Motherboard: Full brand and model name
RAM: Full brand and model name
GPU: Full brand and model name
PSU: Full brand and model name including wattage.
..And so on.

MB: MSI H81M E33
Ram:red 4gb ddr3 + Zion 4gb ddr3
GPU : ATI sapphire r7 250 1gb ddr5
PSU: intex tehcno plus 450 20+4 pin sata 220v

Okay several things here..

1. Like I said, a very crap quality PSU you got there.
2. Mixing up RAM can often lead to compatibility issues, there is a reason they sell RAM in kits, they come from same batch and have been tested to work together.

OK I got it what you said..but what's the solution now.

The same thing happened once when I ordered a bad CPU. Could be a bad CPU.

 

[Kasper Jorgensen]

Depends on your budget, but start with a new and better PSU as you should get that anyway. For a budget build look into a Corsair CX450.

 

[anas115]

CPU!! Really?

CPU!! Really?

Or it could be the motherboard (Bent pins or defective motherboard) Or possibly the PSU. Hard to say which one without being able to test the parts. You can look for bent pins though.

Thank you for your answers and time. One question that comes in mind that if smps is faulty, then how it worked very well for 8 months?

Not sure why you keep calling it smps, it's a PSU and stuff tends to fail at some point or another, specially cheap stuff. Your PSU was maybe working and has now failed for all we know.

I once had a cheap PSU that worked for almost 3 months and all of a sudden stopped working while I was playing a game. It seemed like it had good enough specs to support my GTX 460 that I had back then but I guess it was too cheaply made to last. I doubt the PSU has failed because they usually stop working altogether when they fail.

Agree. It could also be something as simple as a short some where. Anyway he should change that PSU to a safe and better unit.

So,can I replace this PSU and get same model... If possible.

As we already said, DO NOT get the same model PSU as it is a garbage PSU.
