hey
in like january my desktop just kinda stopped. she froze and i went to reboot her and nothing shows up on the screen and after various fucking abouts and arounds with her guts i pronounced her dead but im kinda pissed. i have no clue how to diagnose this - it appears as though it should be running normally but nothing shows on screen; i've tried a new vga cable, a different monitor, my onboard gpu, my regular gpu, and all sorts of fucking combinations of that which leads me to believe it's something cpu / mobo / psu related but i have no fucking clue how to figure out besides just buying a new part and hoping this shit turns on which i don't have the time or money for. she's served me well and is kind of old - 2011 - 2014 r.i.p - but i'm more focused on figuring out what the hell happened then actually fixing it. every light blinks and all kinds of shit is turning fans are goin everything looks like it's working but nothing will show on screen and my monitor doesn't detect it >:/
thanks
If it's the motherboard I doubt it'll boot at all but you can check the caps on them to see if one of them or more has burst (highly unlikely, which is why they improved them over time). If nothing is showing up on screen it's possible it's CPU related, if it was the RAM it would beep. It seems odd that a CPU from 2011 would have this effect though, I still have an AMD CPU from 2005 in my old machine and yet that's still running well.

boot at all as in like even turn on? cause i have no fuckin clue whats goin on if windows is even booting or anything. no beeps so i'm guessing it's the cpu then
huh
i have an AMD Athlon II X3 450 Rana 3.2GHz which has been install since day one (and running well) so i'll fuck around with that a little and possibly order a replacement and see if it works

I've actually had this issue with my AMD FX 6300, I did something in the BIOS so I took out the CMOS battery and put it back in and it was running fine. (Just in case, the CMOS battery is a battery the size of a coin).

how did you fuck w/ your bios if nothing was showing on screen

That was before nothing was showing on screen. I was trying to overclock at the time.

oh ok
so this cmos battery thing
gonna go see if fuckin w/ that fixes it brb ill share results

opened comp up, took cmos battery out, put back in, started, same stuff. would that be the correct procedure

Can you check the capacitors in the motherboard and see if they're burst/leaking or not?
I'll give you some images to help identify them
These are newer burst caps (dead), more common on today's motherboards and other components (like GPU's)

Here are some older one's which may or may not be on your motherboard but it helps.

i was definitely looking around for anything unusual like that and they all look pretty clear. any other ideas?

This is more likely the CPU, if it was the power supply it wouldn't be able to power on at all. Also the same thing that I said about the motherboard capacitors could be true for the power supply but that would mean that it is dead, but you said yourself that it seems like its booting up but it doesn't therefore there's still power going through.
Another conclusion would be a corrupted BIOS perhaps, but seeing as it froze (which happened with my piece of shit HP DV6 before the CPU died), It's leads me even more to believe the CPU is at fault. It's funny, that same laptop had an Athlon II as well lol.

Incorrect.
A PSU can fail in such a way that the machine will power on but fail to POST because voltages are out of range or the PSU is shitting out so much ripple current that nothing will work.
A modern ATX PSU can have up to 6 different voltage outputs (3.3v, 3.3vsb, 5v, 5vsb, 12v, -12v) and numerous physical output rails. Any one of these can fail individually while the others continue working and cause the PC connected to it to malfunction in any number of ways, including not POSTing. I repaired a PC one time where [I]every[/I] rail had failed [I]except[/I] 5vsb. The machine refused to power on but the network card would power on and wait for WOL requests :v:
The CPU is the last thing that you should expect to fail, unless you were overclocking it for an extended period of time with out of range vcore, constantly letting it overheat for extended periods of time or recently had a storm that caused extreme power surges. I've never had a CPU suddenly fail on me that wasn't subject to some sort of abuse, and I've been building machines since 1993.
OP, I'd try a new PSU.
goddammit so we are back at this "order a part and hope it works" method huh
while i didn't have any storms nor did i try to overclock it or anything it definitely did run sort of hot and i totally believe it a couple years of hxc gaming doto and shit at the temps that it did run at could've fucked with it but iirc it was a cpu that ran relatively hot normally

You didn't rule out the possibility, so how can it be incorrect?
The correct term would be: not entirely.
If you want, you can examine the inside of the PSU for visual signs of failure. If a PSU is failing, you can almost always tell by visual inspection of bloated/leaking capacitors, burned components or dark brown/black spots on the PCB.
Just disconnect the mains, tap the case power button a few times, remove the PSU from the case and take it apart. Most PSUs have 4 screws holing the lid on, remove those and the lid should come off so you can inspect the inside.
If you have a good camera that can take clear pictures, you can take 3 pictures (top down, from the left side and from the right side) of the inside of the unit and I can inspect if for you.

You said: "if it was the power supply it wouldn't be able to power on at all."
Which is incorrect, and I explained why the statement is incorrect.

Well, no shit.
The CMOS battery is only there to keep track of the date and time of your PC.

No?
It stores all BIOS settings as well.
You can troubleshoot some stuff for free before having to buy stuf.
If you have an onboard GPU:
Remove the GPU and plug your monitor into your motherboard.
Then remove all RAM sticks but one and try to boot.
If that doesnt work change out the single RAM stick and try again.
If you dont have an onboard GPU you can try the same but instead just reseat the GPU.
Its not posting so its a small chance this would have any effect, but its worth trying anyway.
yeah i tried all of that and none of it worked :(
