Hi!

I have a problem here and having a hard time fixing this problem, that's why I post this thread Hoping to solve my problem.

So Yesterday my PC working perfectly but now I try to start it, it turn on (fan spinning, RGB fan Spinning) but there's no display, there's also no Beep Codes. I try to turn it off using the button in my tower but it doesn't turn off no matter how long I press it, it doesn't off, so I decided to unplug it. Now I try some diagnostic

First I remove my 2 ram and try turning it Hoping that the Beep sound will come, but it doesn't, I also try to clean the ram with eraser and turn on but still having same results, I can't turn off it so I unplug it

Second i remove all the components and start cleaning like (applying new thermal paste in my CPU and GPU), Removing the SATA cable and turn ON, still same outcome, I did try to check if my Monitor is problem but it's not the case


I was looking for answer in Google and YouTube, but the results are PSU problem, IDK if that's true I did some test on my PSU by Turning it ON using Wire, it works but I don't know if the PSU don't give enough Power.

I also have history of PSU problem I'm thinking if the PSU is the problem.

What are you're opinion on this?
Thanks for reading

full system spec? include brand and model of the psu
Is Quite an old System

CPU A8-3870K
Motherboard Gigabyte GA-A55M-DS2
RAM: Skihotar 4GB DDR3
STORAGE: 500GB HDD, 120GB SSD
GPU: Gigabyte GT630 2GB DDR3
PSU: I don't quite know but it's not from Known PSU Manufacturer.
(But this is all I know: 700W Generic, 250W Rated)

I don't know if this enough...

700w, 250w rated? That's not a psu, that's not even a good paperweight, it's a firehazard. Psu's like that should be banned, illegal, as they are nothing more than e-waste.

Recommended psu specs for a pc with a gt630 are 330w, and thats 12v output, not the combined wattage of 3.3/5v rails, which is what that miserable excuse for a power supply has done.

Regardless of whether it's the issue or not, that psu should be replaced with at a minimum of a lower end bronze rated unit like Evga BQ or Corsair CXM 450w. Those at least have certified protection circuits of at least ATX standards.

Once the psu is replaced, and a known good output, then you have eliminated one possibility and can look for other suspects, if it's even needed.

That's indeed true... I kinda hate myself not thinking that, but anyway thanks, I will give you a follow up if the PSU is indeed the problem, and I will check those PSU that you recommend. Thanks a lot
