Parts List

  • -AMD Ryzen 3 1200 @ stock speeds
    -MSI B350m Gaming Pro AM4
    -8GB Crucial Ballistix Tactical DDR4 3000Mhz
    -Thermaltake TR2-500W PSU
    -Western Digital Blue 1TB 7200RPM
    -Windows 10 64 Bit
The Problem
I was upgrading a PC for a friend last night. The new parts are the CPU, mobo and RAM. Everything was fine and the new PC was booting into windows. I accidentally hit the desk with my knee with not too much force and it restarted.

Now all it does is spin the CPU and GPU fans up to max with no post. The error light on the mobo is saying that the CPU is "not detected or has failed". No response from the keyboard or power button. I think I can hear the hard drive spinning up and down.

Steps Taken to Fix the Problem

  • -Switch PC off for 10 mins and then back on
    -Plug out all unnecessary parts and cables
    -Clear CMOS using jumper
    -Leave it running for 5 mins
    -Reseat RAM and check if all cables are connected properly
I also tried gently bumping the PC and the fans actually went back to normal and the error light went away, but it still didn't POST. After I restarted it returned to the old state.

Any help appreciated, thanks.

Ah, completely misread your post. I should probably...
I'm not familiar with that specific Thermaltake unit, but if it is of lesser quality it is plausible that it'll loose power as a function of time, thus ending up in the situation you are in.

If you have access, you can easily verify that it is capable of delivering the correct load within the manufacturers parameters. Alternatively, borrow an already working PSU and swap it in your system. If it works, come back and I'll help you find a quality PSU within a given budget.



The problem could lie elsewhere but it sounds like a dead or insufficient PSU to me.

No it wouldn't be very reputable. How would that be related to the PC restarting when it's moved or bumped?
 


Ah, completely misread your post. I should probably refrain from posting after midnight when my attention-span is lackluster. Having re-read your post, my answer makes no sense. I missed the actual problem and in my tired mind filled in the blanks. I do apologize.

Hmmm, sounds like a weird problem. Would seem quite extraordinary but perhaps the initial bump tampered with the installation in such a way that it would short the system. I would take the components out and breadboad them for testing, only with processor and system-memory. I would also reinstall the CPU and the cooler, given the initial bump, though unlikely, it could've compromised the installation. It's very, very rare though.

Again dude, sorry for misreading your post in my initial reply.
