Tech Support PC won't turn on. Even when stripped down to Mobo and PSU.

Hi everyone,

I have been having trouble with booting my PC on. I thought maybe there was issues with my wiring and the case, so I took out the motherboard. It is a Gigabyte Eagle Z890 and the cpu is an Intel 270k+.

I laid it on my original package and connected the ATX cable and the two CPU cables to my RM750e PSU. I also connected the FNPANEL cable from the case and tried to turn on the PSU and case. No luck, nothing turned on. I even tried to take out the FNPANEL cable and connect the pins with a screwdriver for a jump start. No luck either.

Am I doing something wrong or is my motherboard fried? Thank you for all your help.

Tech Support Buzzing noise when any activity (idle)

Enable HLS to view with audio, or disable this notification

12 Upvotes

So I recently built my new pc, performance, temps etc are fine. PBO +200, CO -20, slight GPU OC, all stable, tested with cine, OCCT and dozens of hours of gaming.

Specs:

X870e tomohawk mono

9850x3d

MSI 5080 trio x

32gb DDR5 CL36

2tb 990 M2 drive

Corsair 1000w Gold PSU .

However I noticed that there is some kind of buzzing/static/surge kinda noise. Not sure if it's happening under load as headphones are on and I'm into the game, with fans also little higher potentially drowning it out, however when I'm desktop, I've noticed when any activity occurs , i.e. whenever I scroll the mouse or browse windows folders etc the noise occurs for that exact moment I'm scrolling or clicking etc, it doesn't persist before or after. This leads me to believe it's potentially CPU quickly spiking in power when activity occurs? Is this normal? Just something annoying I have to deal with? Is this what they refer to as coilwhine?

In the video i have shown that the noise occurs whenever i scroll in this example.

Build Question Updating my PC

Post image
11 Upvotes

I AM AWARE OF THE DUST ON MY PC, IT WAS NOT IN USE FOR SOME TIME AND GOT A BIT DUSTY, I CLEANED IT SHORTLY AFTERWARDS

I have a PC from like 2019, very solid build which has served me well over the years. Unfortunately it is now getting very slow and laggy and I can barely play anything on it or study. I am not a complete idiot in terms of part knowledge but I am looking for suggestions and opinions on the change I intend to make.
The current parts of my PC:

CPU: Ryzen 3 2200G
GPU: Sapphire Nitro RX570 4GB
PSU: Thermaltake Litepower 650W RGB (newest part i bought probably 3 years ago cause the old one couldn’t keep up)
MOTHERBOARD: Gigabyte A320 (GA-A320M-H)
HDD: Western Digital 1TB WD10EZEX
RAM: The first piece is Corsair Vengeance DDR4 3000mhz 8GB
The second one is: TeamGroup DDR4 2400mhz 8GB (ted48g2400c16bk)
The cooler is the basic one that goes with the CPU, my PC has no SSD and the case is really random I don’t even know the name. I have small budget but I want to make some updates that I am gonna list below:
CPU: Ryzen 5 5600
Cooler: DeepCool AG400 G2
SSD: TeamGroup MP33 1TB
I intend to play games such as ARK Survival Evolved, Counter Strike 2, Unturned, League of Legends, Grand Theft Auto 5 but mostly will use it for studying. I am open to any suggestions for updates and will not put a specific budget although I want the new parts to be budget friendly because I am not currently ready to put big money into my PC.

Heyo, I hope this is the right place to ask for help with this. My 8 year old, second-hand parts, Frankenstein pc finally needs something replaced- the motherboard gave up ( as determined by the local pc store (who was insisting I should spend $$$ I don’t have to just buy a whole new pc)) buuuuut I genuinely don’t know what I’m looking at :/ I don’t know where to start and I need help identifying the board to figure out a replacement part
Please help 😅🙏

It’s a msi mag a1000g pcie5 and I got it bc of a high tierlist rank, but the 12vhpwr pins seemed a bit uneven and the 24pin mobo cable is SUPER uneven and some of the pins wiggle when I touch the wires. This has gotta be a qc issue right? Would yall run these cables or just return it

Installation Question AM4 Ryzen 7 5800 X3D

4 Upvotes

Picking up one of these am4 chips to maximise my am4 build and life cycle.

Noticed its anniversary edition with a Carbice ice pad thermal pad so can be used without paste. I'm using a Peerless Assassin 120se cooler which keeps the temps pretty good on current CPU.

Never saw these pads or used them before. I can see benefits as no paste everywhere or needing replaced.

Anyone used one or have opinions on them from use?

I currently have an XPG Gammix D30 8GB DDR4 3200MHz (AX4U32008G16A-SR30) and I’m planning to add an XPG D35 8GB DDR4 3200MHz (AX4U32008G16A-SBKD35).

Both are:
8GB
DDR4
3200MHz
CL16
1.35V

Would these work together properly in dual channel?

Is there anything I should be concerned about regarding compatibility or stability?

Thanks in advance btw!!

Tengo estas dos opciones de fuente de poder para empezar una pc que llevará una carga de trabajo medianamente pesado, no sé mucho al respecto, he visto que corsair es la más recomendada pero la única disponible es de Corsair CX750 80+ Bronce y cómo es una fuente que quiero usar para el futuro también, pensaría que la MSI MAG A850GN PCIE5 80+ GOLD
sería mejor opción ¿que me recomiendan?

I've switched out my old 512gb SSD with a 1tb SSD that was on a more modern system, and at first when I booted it showed only blackscreens before booting into windows, but when I tried booting into safe mode it just loaded forever, idk how should I format it? Oh and also I switched back to my old SSD but I can't get into bios either and it doesn't show me the logo while booting in

Build Question cpu cooler enough?

2 Upvotes

Hi All, specs of my current build

  • CPU - AMD R5 7600 (stock cooler)
  • RAM - TeamGroup (2x16gb) 32gb CL 30 Ram (purchased in 2024 for $95 I know I lucked out)
  • MOBO - Giabyte B650m Aorus Elite mobo
  • SSD - Silicon Power 4TB US75 Nvme PCIe Gen4 M.2
  • CASE - Lian Li A3 case black ventilated no window side panel
  • PSU - Seasonic Vertex GX-750-750W

I plan to upgrade CPU to R7 9800X3d and I purchased THIS cooler on amazon. I wanted to know if it will be sufficient enough to cool 9800X3D. I prefer the top-down cooler just for airflow purposes. i currently have a chimney style cooling setup with just 2 be-quiet! 140mm fans exhausting out the top.

i'm open to recommendations and suggestions, and yes i know I can fit a tower cooler but how would I implement that with chimney-style airflow?

I just built a new case and i forgot how to connect the GPU and the CPU to the PSU.

I have:

- 4090 to 3x 8 pin adapter
- 2 cables which have 8pin on one side and 2x 8 pin on other
- 1 cable which has an 8 pin on both sides

I tried with the cpu having the direct one but then the gpu didnt start because it was powered by only 2 8 pins on psu side. im a bit scared and dont want to fry anything. Can someone tell me how this needs to be connected? Thank you so much!
