Computer having troubles starting up and shutting down.

[JeronStevens]

My computer has been acting up the past few months and I've fixed a lot of problems already, from constant freezing to not booting.

About two weeks ago my computer hasn't been shutting down correctly. When I choose shut down, it shuts down, but a few seconds after being off, it restarts. About 75% of the time when I choose shut down, it restarts. I don't get any error messages, or even the "windows did not shut down properly". It just acts if its being restarted.

Today for the first time, I powered up my computer. It would start the fans and all the start up steps, but a few seconds after my BIOS splash screen appears, the computer shuts off, then trys to start up again. It kept going from starting to stopping, then restarting for about five minutes, then it finally stayed up.

What issue would this be? I don't want to shut my computer down again incase if it won't boot.

A machine power cyling like that could be memory related, but could also be the board. If the memory is in 2 sticks, try one at a time.

I tried just one at a time, and running in diffrent duel channels

Have you tried reseating the CPU?

 

[JeronStevens]

No I have not.
For the first time, I took it to a PC repair shop. At the very least they are doing a free diagnostic on the hardware.
I’ll let you know what becomes of it.

Thank you. Would be of interest what they find.

Thank you. Would be of interest what they find.

They claimed it was a bad power supply, I knew it was either that or the motherboard.
They said the cheapest replacement that could find was 130$, plus a 99$ service fee.
I went to Best Buy and got a 40$ one and installed it myself. I’ll let you know if it works or not once I get home with it.

Hoefully that fixes it for you, out of interest what PSU did you end up getting?

I wanted to get th EVGA 450w, but Best Buy was out. Don’t freak out, but I got an Insignia 450w.
I know that their brand isn’t the best, but it was like 50$, I didn’t want to wait like a week to get a new one in the mail.

 

[nmsuk]

I think I'd have waited and I shall try to not freak out.

Is it at least 80 gold certified?

 

[JeronStevens]

It’s 80%+ efficiency. I didn’t see any certification on it.

Please give me grace, I’m just a poor college student that likes light gaming.

Hey no judging from me. Well maybe a little. But hey if it works then great.

We've all been there when a psu has gone and have to get a cheaper one.
