GPU Video card died (VGA/ DVI /HDMI/ DP)
GPU = Graphic Processor Unit (chip) or that magic chip that makes your Monitor screen show video or windows screens of any kind.
You are here for desktops or from my black screen of death page.
Your PC monitor is ok , you tested it on any other PC and the monitor always works, if not then see my monitor dead page.
This can be a dead GPU chip on the motherboard, or the PCI-express Video card failing.
The Graphic Processor chip, (many get way too hot and go nuts or shut off , or if too hot they fail) so clean the PC first.
On this page when I stated VGA jack that means (VGA/ DVI/ HDMI /DP) as the case may be (no pun) what you have there matches your monitor is only what is wrong matters now.
My PC I am typing now has 1 DVI on board (core i7 processor ) and 1 video card with 3 Jacks for all kinds but VGA. (I have 4 video jacks)
When I say dead screens, that means only BIOS fails dead black screens, as any booted OS will fail if the BIOS is dead already, if bios can not not present simple 2D video.
One very odd thing about some BIOS is that if the RTC coin cell battery dies BIOS goes dead, black screened, some with a warning or other just pure black screen, so we test the battery first for sure over 7 years old.
This page I am doing here is just on the 2 possible GPU chips to fail, many a PC has 2 GPU CHIPs. 1 onboard and 1 on the slot.(some PCs have no GPU on the motherboard at all)!
If you do have 2 GPU 's, then remove the ADD-IN Video card and see if the onboard video jack works now. (yes move the video cable as you do this)
When I say GPU engine and not chip I mean the 100% hidden GPU logic is deep inside the Intel ™ (core processor ).
So the GPU can be in 3 places, or 2 of 3 places. The CPU+GPU, the GPU on board or the GPU SLOT.
If you have a GPU card in a slot and it fails remove it first and use the onboard 15pin VGA jack. As seen here.
The on board GPU many times is a (Nvidia or ATI/AMD) or is part of the main processor (CPU) as seen on Intel CORE i3 to i7 processors.
If the GPU is dead the cause is usually BAD PSU, bad DDR RAM or some module in the PC is shorting, if fans are dead, bingo power overload.
Lets say the onboard GPU works but only the Video card fails. (this many times is the owner forgot to connect up the GPU card AUX cable)
Keep in mine the 2 ways to see if a GPU is dead is not using windows, one can just use BIOS screens, even with no HDD present. (total dead GPU now is a very serious matter we do all trouble shooting here in BIOS)
(I will never cover old PCs with old LEGACY non express PCI and Old AGP cards)
The video card most times fits the top most 16x PCI-express slot (the long one) some PCs have 2 of these slots, and the manual tells you what slot is GPU enabled. (top slot on mine it is)
The BIOS automatically today switches GPU to the slot when the card is inserted, (never hot plug/switch power and cables and plugs inside a PC nor those PCI slots.) (please save your PC and unplug AC power cables)
The GPU card , like say a GTX660 card, needs TONS of power (the word power means in electronics WATTAGE, but in Ohms laws it is AMPS times volts) P= Amps times volts. (D.C power in watts)
The manual of the best GPU cards cover this topic that most never read, so if you read mine, it tells you this power hungry card needs 30 amps of power. 12x30 = 360 watts just for the CARD, the whole PC needs 550Watt PSU.
The Cards that suck (draw) huge currents all have, and AUX power jacks.
The reason is that the PCI-express slot is limited to 75watts max. (so vast numbers of fast GPU cards all have AUX jacks and fail if not connected to a PSU using the AUX cable or the PSU is too low wattage rated)
4 pin , 8pin AUX are common to be seen.
If you fail to buy a PSU rated for 550watts and more or fail to buy the PSU version 2.2 ATX-12V and higher (2.3 is much better) PSU the AUX cables will be missing discussed here at length.
If you ignore the power needs or that AUX jacks, the PC will be dead, or madly crashing BSOD, even in the middle of some intensive expensive game.
Most modern motherboards have one 4 pin AUX all by itself and if yes, most PSU have at least 2 AUX (4/8) pig tail cables already.
If all the above is OK, but PC crashes, even to a blue screen of death, get new drivers from Nvidia or that ATI chip at AMD.com as the case may apply. (or from your OEM maker of PC or video card)
If you only have 1 GPU chip , get the driver first. (from your OEM PC maker first, or if home built PC , from the motherboard maker (ASUS is top shelf) Asus.com
Installing a driver in to windows will not fix any dead BIOS screens. BIOS runs with the HDD or SSD removed so there is no driver at this level of logic. (but is in the firmware; yes)
A better video card is the GTX1050 (It never needs an AUX power jack) It runs fast and cool like magic, buy one and love it.
The 1050 uses only 72 watts max, about 5 times less than my 660 needed. (And amazing feat due to die shinks at Nvidia)
The #1 reason for BSODs are bad video drivers. Upgrade your driver.
Next is bad RAM
and last is a PSU with huge noise on the rails (the Capacitor plague ,wiki that)
See a very good desktop below in he better case size , big.
See the VGA is onboard. see addin card slot is DVI/HDMI
If say the DVI slot is dead try the hdmi if both are dead remove the addin card from the PCI-e slot and VGA port can not be tested.
The DVI here is a card slot, called and Addin card.
