I have read many peoples problems about PSU problems on here and you guys are pretty helpful so I decided to ask you guys. So, I am a newbie to computer, I bought a "Standard 80 Plus Certified Power Supply - SLI/CrossFireX" from Cyberpowerpc.com when I made my custom built computer. I did my research on graphics cards and cpu but not PSU.

To simplify the text below: had problems turning the computer on, had problem with motherboard, temperature readings on mother board changed drastically, and I smell something like burning rubber. The problem I think is that my power supply is failing, what are your opinions? Is there a way to check psu stability without opening up computer, like maybe on software? Any help would be great, thank you.

Here is what happened in detail: yesterday on 3/3/16 I turned on my computer. The light turned on and the screen kind of froze. So I manually turned it off and on. This time keyboard stopped working. I turned it off then on. It started up the usual way. Everything seems fine. Later through out the day I would shutdown computer and restart it, still everything is fine.

The next day today, 3/4/16 I turned computer on. The light for computer turns on, makes a sound like its reading a disk, maybe ram, but the sound was persistent. The monitor didn't turn on. I look down at my monitor the motherboard doesn't display temperature readings says 00 Celsius. I unplugged it from the wall and turning it on and off. I saw that the motherboard displays 04 Celsius.

I repeated the process the display screen on the mother board showed different numbers too fast to keep up with," B7, E4, etc" and then finally it went up to 64 Celsius. My motherboard never went up to 64 Cecilius and I don't think that it is a safe temperature. After some time temperature went down to 32 and monitor turned on.

I sometimes feel like I can smell burning rubber. I have read online that it can be because of dust or the psu is burning up.

Edit: Well the numbers I saw were not from my mother board but my cpu according to Cyberpowerpc support. The customer support suggest I do a memory test, maybe there is a ram error.

Do not touch anything that risks your warranty.....

You can still inspect unless you need to break some seal.

B7, E4 are hex numbers may or may not be error related.

See what memtest reveals but I doubt that a memory card failure would have a "burning rubber" smell.

Remember that CyberPowerPC has a vested interest in finding or otherwise blaming the problem on something else.

Check everything out as best you can. Watch the system's behavior very carefully.

You need to open up and inspect the computer's components. Everywhere, everything.

Good lighting, magnifying glass, dental mirrors. Do with power off and unplugged.

Obviously something is overheating to the point of burning. Finding that item is the first step. Determing why it is overheating is the second step.

Could be a bad, over-loaded/under-performing PSU. Could also be a faulty connection, failing fan, blocked ventilation ports, electrical short.

Dust and dust bunnies can get hot and create an odor. Won't be a burning rubber-like smell.

Go over your build and check everything.

Thanks for the reply. I may have been smelling something else, I have asked two other people if they smell anything and they both said no. I just got the computer 8-9 months ago and I don't want to mess up warranty. I will eventually have to get my hands dirty and touch the hardware, but I as a newbie I don't want to mess with a $ 2,000 machine. I talked to the customer support from CyberPowerPC and they told me to look at memory errors. I will try that with memtest86. Can it be memory problems, did I have a wrong angle for thinking PSU? my memory card is a "Corsair 16GB (4GBx4) DDR4/2400MHz Quad Channel Memory "

You are definitely right I should inspect the PC carefully. I will also do prime95 to test CPU and furmark to test GPU . The burning rubber smell however may have been my fault since other people don't seem to smell it.
