No signal from GPU

[Tagara]

So a friend of mine decided to remove both all of his RAM and hus GPU, for fun and for the first time. It seems like he has done everything right. He threated the components well. Now, when he has installed his GPU again, which is an MSI GeForce GTX 750Ti Gaming 2GB PhysX, and connects VGA or HDMI (tried both) there is no signal to the screen. We have removed the GPU, and are trying to use the GPU. So far without luck. We are currently running RAM test, using one stick at a time in each of the RAM slots. Still no signal to the screen. We have tested all components that we was removing / installing again. The GPU's fans are running when plugged in too. The RAM is some Kingston HyperX that are white. If you need the exact kind of RAM, tell me and I'll ask him.

what are all the components?

cpu, mobo, psu, ram, monitor

[Tagara]

GPU - MSI GeForce GTX 750Ti Gaming 2GB PhysX

MOBO - ASUS B85M-G, Socket-1150

RAM - HyperX Fury DDR3 1600MHz 8GB White

PSU - Cooler Master B500, 500W PSU

GPU - Intel Core i5-4590

Screen - Asus 27" LED MX279H

Again, he only removed the RAM and the GPU.

You said this was his 1st time removing the items..
Some things to consider..
Loose connection to some other component while removing and replacing items..
Could of caused a hairline fracture to the motherboard, if there was any tugging envolved to remove the items..

Myself, I'm having a similar issue, but my screen went black and all my internals appear to be working, while browsing these forums, not after pulling out and replacing components..

You didn't use any canned ait to blow any dust off did you?
If you did, you must remember to always keep the can upright.
If not, you run the risk of the air turning to frost, and can damage the circuits from the moisture,

His PC is actually quite new. So it is not dusty yet. So you recommend that we check the connections of the wiring, or do you mean that he managed to destroy the MOBO?

sometimes when removing things from a pc, you may inadvertantly loosen a connect to another wire, Just check that all wires are still fulling plugged in. And as far as ruin the MB, only if you used force to remove the ram and video. This may cause the board to flex and may cause a crack.. HIGHLY unlikely, but still a possibilty....
There is also the chance of static.. He was grounded before touching any of the components I hope.. :)

Won't you notice if something is being affected by static? There is a green light on the Mobo when turned on. Not sure if the mobo is killed completely or if the light may still work after some static.

[L0WHAWK]

static could affect any component.. not just the motherboard. this includes the video card and the ram.. also you aren't supposed to touch the little copper points that you plug in, aka the bottom of the ram and video card, with your skin.. the oils from your skins will adhear to it and can cause problems..

if the 750ti has a 6-8 pin power connector, make sure its connected to the psu

cm power supplies are not very good, but it should be enough for that build

The GPU has no pin power connectors. (Not sure why, but it does not have.)

750 ti runs off the PCI slot power. No power connector on those.

are you using any adapters?

most newer cards only have 1 dvi-i port (that work with vga adapters)

no signal to the screen

is the monitor plugged to the wall socket and turned on?

if the monitor is plugged and turned on, the video cable (dvi/hdmi/vga) is attached to the monitor from the gpu video port, the computer boots with no error beeps, do this: turn off computer and unplug it from wall socket.

open pc case and remove gpu from pci-e slot.
clean the tips of the nvidia gtx 750 ti with clean paper or soft eraser.
re-seat gpu properly. if there are screws that hold the gpu into the pc case, tighten it.

then do following checklist:
1. psu 20+4pin main power connector is attached to motherboard, usually at right side of mobo.
2. psu auxilliary 4pin power connector is attached to motherboard, usually to the left and above cpu socket.
3. memory modules properly seated.
3. sata data cable from the motherboard attached properly to storage (hdd/ssd/dvd-rw)
4. power cable from psu properly attached to storage )hdd/ssd/dvdr-w)
5. psu switch is turned on.

close case.
plug computer to wall socket.
attach video cable from monitor to gpu video port.
turn on monitor and computer.
see what happens and listen to any beep pattern.

It's possible that if the system has Integrated Graphics (IE Intel i-series CPU with Intel HD or AMD APU with AMD Radeon) then he needs to plug the monitor into the motherboard (integrated graphics) and then manually select the GTX 750 ti GPU as primary in BIOS.

Also if it's one of the models with a PCIe 6 pin plug he needs to put that back in, most don't have it but some custom designs do have it to allow more overclocking.

Yes, some 750 Ti have the 6-pin connector, on the side, not the top. So please double-check all wired connections throughout the system.

As far as manually selecting GPUs, motherboards have not been that way in many years now.

Just make sure the display is connected to the NVIDIA GPU and not a display based port of any kind on the Motherboard I/O

We have already tried to use the intergrated graphics of the CPU.
