So I just finished building my first PC.
When I power it on, everything in it seems to turn on. Except I can't see anything boot up in the monitor. It turns on for a bit, says no signal, then turns back off. What could I have done wrong.
- the cable to the monitor is plugged
- the graphics card is working
- the graphics card is powered up correctly (appropriate power cables, enough power from the PSU)
Try plugging the monitor to the mainboard instead. If it works, it means the problem is with the video card (drivers, insufficient power, not plugged in into the PCI-E slot correctly).
A common newbie error is forgetting to plug in the power cable to the graphics card.
Intel i7 4790k
evga geforce 980ti
16 gig ram
240 gig SSD and 1TB HDD
I tried plugging it in to the motherboard but it still wouldn't show anything.
It's a displayport cable
>case uses lil nubbies for motherboard mounts
Well that's a really fucking good rig. Everything's super solid, and the case and PSU are absolutely god tier.
- Check if the case cables (power, LED) are inserted correctly. Make sure you haven't flipped any + and - ones.
- You can also turn the PC on by removing the case cables and putting a screwdriver between the two "power" rods. Make sure the screwdriver is isolated (do not touch the metal part)
- Check if the motherboard is mounted correctly. It should not touch anything metal on the case.
- Check all the power cables for motherboard, CPU, GPU.
- remove the middle module for HDDs. You only need the bottom one, and removing the middle block will improve the airflow..
- you should be able to place the CPU cable behind the motherboard
You've said "everything in it seems to turn on". Which fans are spinning, what heats up? Do NOT touch anything while it's under power, turn it on for a while, turn it off, wait a minute, then examine the radiators (also north/south bridge of the motherboard).
I have a very similar build (same mobo, cpu, gpu, and an SSD/1TB HHD setup) and ran into the issue of my SSD not showing on my boot device list. For some reason the 97-a was only showing the HHD and trying to boot from that.which of course does not have my OS. I had to clear the CMOS to get to the BIOS and change my drives to different SATA ports.
I checked everything on here and everything was fine. I decided to check if everything was plugged into the PSU correctly, now it works. I'm guessing something wasnt plugged in all the way. Also, i took off the middle module for HDD and the CPU cable is just a bit short.
Thank you everyone for trying to help.
If your "boot device led" is on, then you are running into the same problem I had.
Clear CMOS (RTC RAM):
* Turn off computer and unplug the PSU.
* Remove the CMOS battery.
* Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on
pins 2-3 for about 5~10 seconds, then move the cap back to pins 1-2.
* Reinstall CMOS battery.
* Plug in the PSU power cord and turn ON the computer.
Before turning the computer back on, ensure your SSD is connected to your SATA 6 port (the lowest SATA port on your mobo). Mine was plugged into SATA 1 and not showing on my boot device list. Boot into BIOS and go into advanced options to check your boot device list and ensure that your SSD (if it does indeed have your OS installed on it) is the second option behind your optical drive in the boot device list.
ONLY follow these instructions if your "boot device led" stays on at startup. If it is not, check to see if another led is lit on your mobo when you power up.
