PC would turn on, but no display, but all fans spin??

[Blazepoint5]

Hello humans and welcome. My PC has some issues that even I couldn't figure out, but I have a hunch. So, if I turn it on, the CPU, drive, exhaust fan, and GPU would turn on, but there would not be a display. I tried removing the CMOS, switching PSU from 650W to the 250W it came with, reseated the RAM, tried booting without RAM, tried booting with no drive, tried using the DP on the motherboard, not the GPU, but that thing refused to display.

 

Went to a PC store and told the guy the same thing; he reapplied thermal paste, and boom, it worked (note the CPU wasn't overheating or anything; I know the temps). Maybe 3-4 days later, we were back to square one. I tried reseating the CPU, but nope.

 

Three weeks after the CPU had been sitting and collecting dust, I took it for a check again. This time, the guy reseated the RAM, and that boot up, like bruh, I did that before coming and didn't get any POST. I ended up getting 4GB of extra RAM (new) because he said the RAM was weak, I guess.

 

Three days later, boom, back to square one, but this time, if I boot the PC, the keyboard light (CAPS, Num Lock) turns on; I don't know if that means anything.

 

Now, if I turn on the CPU, there's a 50/50 chance it would work, and if it does, the PC would be working for like 2 days, and maybe on the 3rd day, it wouldn't post again, no matter how I try. Sometimes it only works for a day, maybe 2, and yeah, same same, been a month or so.

 

Oh, and I did a diagnostic test of the hardware, and it all checked out. I got a new drive for a fresh Windows install, but nope. I reinstalled drivers with DDU, and it's not my PSU because, at the beginning, I mentioned swapping the PSU.

 

This is a long message, but I hope you find it somewhat useful. Thanks for reading.

Swapping to a weaker psu doesnt tell much. 

 

Most of the things you said usually leads to GPU or MOBO fault. But its hard to tell without full spec.

If possible try with diffrent cpu. Since you can buy 4gb of ram i think its a ddr3 system. If that is the case mostly mobo...

i5 2500

gigabyte rx 570 8gigs

12gigs ddr3 4x3

cosair tx 650w.

 

the pc is a dell Optiplex 790 so motherboard, cpu and drive came with it, its not new nor clean, it has seen the light of day if you get my point.

i didn't to see if its a psu problem, like I tried to boot the pc using the specs i got it. 

 

i5 2500

gigabyte rx 570 8gigs

12gigs ddr3 4x3

cosair tx 650w psu. 

 

the gpu isn't old, the dude i got it from barely uses it, no artifacts or over heating if i can tell. my hunch was the motherboard too actually, its hard to find a chip where i live but nothing impossible.

Hello and welcome humans. 

I made a post about this like weeks ago, i would recommend you to check it out because it would make more sense. 

SPECS

I5 2400

dell optiplex 790

8gb ram (now 16) 1300mhz ddr3

rx 570 8gb.

 

i did all the trouble shooting known to mankind but i have finally found the problem to why my pc is not posting, ram

cmos

cpu

psu

hard drive

i went as far as getting a new ram sticks, and spent weeks saving to change the motherboard and cpu but after i got home, plugged the thing... well it was spinning like a vacuum cleaner, the  pc worked when we tested it with a different gou at the shop i got the mobo. 

it truly hurts, after all i have done to get this gpu it bailed on me, got it around February as my first GPU or first build. 

 

i noticed a capacitor on the pcb 

 

I think it has been like this when i got it, there is some rust to on the back plate and a bit in the ports but it worked w no problem until now. got it for around 48,000 in my place or 33usd at the time, now something like this cost around 110,000 cause of inflation but that a side. 

 

im afraid to going back to square 1 because going backup is not something i can do again, any information would help. Thank you.

Did you try a different video cable?

 

Is there any possibility that your home's electrical system is not grounded or otherwise not done correctly? When I lived in Indonesia, that was always an issue.

did all does, i even used DVI, all ports, different cables more.

Do you mean it spins up when you plug in an external power connector or when you plug in a display cable?

Noted, wouldn't make the same mistake.

look for a connector that has 8 or 6 holes on it in a grid. considering you have a card that pulls more than 75 watts, which is what the PCIE slot can provide, usually what will happen is the fans will spin at max rpm and a message SHOULD appear on your monitor saying to connect GPU power cables. unless I misread, this could be the issue. your card might also have a broken video output so I recommend trying all of them.
