CPU turns on and off

SFOpilot · Jun 4, 2014

Hi, my CPU Keeps turning on and off. I've tried possible simple solutions such as disconnecting and reconnecting internal and external wires, cleaning the inside, and cleaning the computer (software.
However sometimes when I do get lucky it turns on and I can actually use for a long period of time, but sometimes too it will boot up the monitor then freeze forcing me to restart it then the turning on and off problems happens. Most of the time when its off and I decide to give it a try to turn on, it will do the turn on and off problem. Please give me a diagnostic before I can actually go to a computer technician.

You may have a faulty power supply.

neon neophyte · Jun 4, 2014

ill go a step further and say you most likely have a faulty psu and even if you dont that psu has no business being in a computer and you should replace it before it blows up your computer. that is a tier 5 psu, ie, the worst psus on the market and they should never be used for anything other than a paperweight

@neon neophyte, what brand and wattage do you suggest? Keeping it under $100

maurelie · Jun 4, 2014

I would say both Ryan and Neon are right, it looks like faulty PSU. Avoid Raidmax and all their products like PC cases and PSUs, they always have made products with bad reputation and i don't know why they still exist.

Tbh I'm not very knowledgeable with computers, I believe I have this PSU http://www.newegg.com/Product/Product.aspx?Item=N82E16817152028

and I was wondering what PSU should I get?
I got a couple questions:

Will a higher Wattage affect my computer?
Will replacing the PSU delete my files?
Are all PSUs same in size? ( i dont wanna buy something that wont fit in my case.)

maurelie · Jun 4, 2014

Higher wattage PSU will not affect your PC
Replacing PSU will not delete your files.
90% of the PSU are the same size.

PSU for your setup, between 500-550w
Good brand with reputation and cheap one:

Thanks so much for you direct and positive response. I was considering getting a Corsair TX or CX Series power supply would you agree?

maurelie · Jun 4, 2014

Tx yes, CX definitely no. Corsair's CX units use low quality capacitors which will wear and heat up fast. CX units are considered as budget units and used for office systems or PC that will not use power hungry GPUs or CPUs and there will be no overclocking involved. As for the TX, that is the right choice.

Corsair Enthusiast Series TX 750 Watt ATX/EPS 80 PLUS Bronze (TX750)

Is this good? Oh and do you think a guy like me could install this myself?

maurelie · Jun 4, 2014

It is pretty good, but it is too much for your system, although you will buy some headroom in the future if you will be installing more power hungry GPUs.
As for the installation process, it is pretty simple. There are many tutorials or videos on youtube for installing PSU, or read the motherboard manual, everything there is writen and explained in pretty simple way.

Btw how much are you willing to spend on your new PSU?

SFOpilot · Jun 4, 2014

I might just consider buying what youve recommended, possibly I might overclock in the future. I willing to spend $100

maurelie · Jun 4, 2014

This is the best offer i could found right now. XFX 750w Fully Modular (meaning less cable mess and easier installation) 80+ Gold certificate (very good for power consumption) for $87
