Resolved Question

Pc stopped working, when turning it on I see green squares

May 11, 2017 2:06PM PDT

I was playing Overwatch when my computer suddenly froze and shut down. When I wanted to turn it on, all fans were going off and some green squares appeared and thats it. My screen goes black, and the fans are still going nuts. I am not an expert, I am a noob in the PC department but I would really appreciate if someone could help me out.
This is a picture of how my screen looks https://ibb.co/fvxA35
Thanks in advance.

Clarification Request
Did you check the capacitors on motherboard?

Now that we see what this is made of.

I'd try another GPU. The machine is pretty old so this might be another component but graphic fails like that usually are caused by the GPU.

Thank you, I'll try to find a GPU and test it out. I'll keep you posted.

It was the GPU

I tried to run my PC with the card of a friend and it worked, it turned on. So I guess I'll have to get a new one lol. Thanks for the help!

Thanks for the report.

While the CPU issue is there, it worked so if I could I'd let that be and work the GPU.

The 560 is pretty old so what would I buy to replace it without hitting the PSU change limit?

The Nvidia 1050.

Thanks for the recommendation

Funny coincidence, this is exactly the GPU I was looking at the other day, thanks for the info. I think I'm gonna buy it.

Details
May 12, 2017 5:14AM PDT

Im sorry i didn't put any details, but i have checked what I have.
Motherboard - ASUS Z77-A, 1.5 years old
Power supply - corsair CX500, 1.5 years old
2x 4096MB (DDR3 1333 MHz)
CPU - Intel Xeon E3-1240 (4 cores/ 8 threads, 3.30 GHz, 8 MB)
GPU - MSI nVidia GTX560 Ti Twin Frozr II

The originals stuff that were in my PC I upgraded, only the CPU, case and the RAM remaining. It was a workstation from fujitsu called CELSIUS W510 proGREEN. But like I said, i removed everything but the case, RAM and CPU.
Thank you in advance.

Unsupported
May 12, 2017 1:18PM PDT

It means you have a square peg in a round hole.
You can not plug 'any' cpu into 'any' mobo, that might not work very well.
The mobo maker shows a list of supported cpu's for their mobo.
If you install something that is not on the supported list the results are unknown.

Ask whoever fitted these together how they expected this to work.

CPU
May 12, 2017 2:44PM PDT

But how did it work till now? I mean I understand what you're saying, I just dont get why it worked fine till now. But yeah, I had to replace the motherboard because I changed the GPU but couldnt afford​ a new CPU at the time. A friend told me it would work. Good to know.

The failure looks like the GPU
May 12, 2017 3:18PM PDT

But the CPU issue is gaining attention as Microsoft updates the OS and blammo, things blow up.

I AM NOT WRITING THE CPU IS DEFINITELY THE ISSUE IN THIS CASE but it's not a good thing.

How do you know that?
You might have been running at 50%.
I don't think it's your screen problem just something to keep in mind for the future.

You're right. It was a sloppy fix, I'll have to do a better job researching next time I decide to change stuff like this. Thank you for the advice.

Display problem

The most likely suspects are the video card, cable, monitor.

Reseat the cable both ends, that's free to try.
Then depending on what parts you have access to you start swapping.

Faulty GPU
May 16, 2017 10:54AM PDT

Yeah I just got a GPU from a friend and my PC turned on. So I guess it really was the GPU.
