The CPU with the graphics card as mentioned in the title is showing a red light and cannot show anything in the monitor even though the CPU can start. After a while the computer started fluctuate between on and off after I turned it on.

A different CPU works and projects images in the monitor just fine.

Could someone please tell me where the problem may lie?

Am i right to assume you are talking about "GPU" and not "CPU"?

The red light on the video card suggest it is not getting enough power. If the card is not getting enough power it will not display on screen. (green light = power, red light = no power)

A. did you plug in the card direct from the PSU normally a 4 pin connector on the back of the card?
B. what kind of PSU (power supply) do you have, how many watts?

Also keep in mind the card itself may very well be defective.

I'm talking about both and two CPUs in comparison. The first CPU with the R9 270x and the second CPU without the R9 270x.

My question is, what is wrong with the first CPU? It is projecting a red light near the R9 270x area and the monitor does not project images. The second CPU is working just fine, projecting images in everything.

EDIT: @rdizz81 I see. I don't know how the card is connected because I don't know anything about assembling computers and I wasn't the one who made this. I'll keep what you said at the back of my head and see if I could fix this.

What kind of power supply do you have? and i am still a little confused here. You changed the CPU (the processor) and that same video card worked and the computer booted just fine? and when you swapped CPU's, that same with the same video card the computer no longer produced an image?

would really help to get all of your system specs here.

What kind of CPU's are you swapping?

It also sounds like you have onboard video, and when you are plugging the monitor into the mainboard and not the GPU you are getting a video signal. am i correct on that?

The second CPU didn't have the same graphics card as the first one and it worked fine on everything. Maybe CPU was a poor word choice, I might have meant a different computer if that's what you're trying to clarify.

800 Watt -- Standard is my power supply apparently.

My bet is on either
A. your PSU cannot support the wattage needed
B. it is not plugged in properly
C. Conflict between onboard Video and Video card


try taking a look at this. will help explain a lot.

**EDIT** your psu is more than enough wattage.

I guess the motherboard has nothing to do with it?

Yes when you were saying CPU i was thinking you were swapping Processors. Ok this makes sense. So to clarify you tried the same video card in a different computer correct? and it worked?

So this should rule out that it is a bad card. 800watt psu also rules out that it is not enough power.

Motherboard and Processor can make a difference because i am leaning towards haveing a conflicting issue with Onboard video. Is this a "homemade" build or is this a store bought branded machine?


**EDIT**

ok re-reading your OP you didn't swap cards just Monitors. I am back to i bet the video card is either not seated properly or it is not plugged in & it is still possible you have a bad card.

So open the case check to make sure the video card is not just plugged into the board but has the 4 or 6 pin connector plugged in from the PSU to the back of the card.

randomly restarting could be a short somewhere or possibly bad ram maybe as well. If it is plugged in and you still have same problems red light and all i would try removing one stick of ram if you have 2 in there and boot if nothing remove that stick replace with other stick. try to reboot. Look at that link i posted a few post back. will really help you understand what is going on, and i have a feeling going through that check list STEP BY STEP will in fact solve your problem.

It's from ibuypower and the warranty just ran out. I didn't swap monitors, it was the same monitor but two different computers.

1.) The first computer with the problem on the graphics card (red light) as I said; the monitor wasn't showing anything.

2.) The second one which didn't contain the graphics card and was working fine showing images on the very same monitor.

Ok something went bad, Its either Ram which is fairly common. Your PSU or The video card itself. (in fact it is possible that any component went bad Motherboard included, maybe power surge overheating number of issues) Could be one of those instances when you start throwing parts at it. A hard drive cannot be ruled out here as well. But since you are getting those red lights i would almost bank on replacing that video card will fix your problem.

you can test that same video card in the other computer. If you are going to be doing this on your own make sure you are grounded or touch something metal before you touch any of the components.

You will want to test that video card in another machine to make sure the card is not bad (that being said needs to be tested in a computer that can run that card)

1st step IMO would be to test the ram as i stated above.

because its is the easiest thing to rule out.

***ALSO i do want to confirm the red light you are seeing is on the actual VIDEO card correct?***

If you are not comfortable yes. However your warranty on the computer may have run out but i bet that card has a 5 year warranty its worth giving the card manufacture which is NOT ibuypower a call see if they will do a warranty replacement. And save you a ton of money. Basically pull it out and push in the new one.

I used a different PCI and connected that instead of the previous one and the computer which didn't display anything on the monitor is now working. But it will not boot on normal mode (Yet it works on safe mode) for every time the software/driver for the Sapphire R9 270 Dual-x OC GPU is installed.

Could someone please tell me what is going on? Is it about time that RMA the graphics card?

I've tried:

1.) Clean boot
2.) System restore
3.) Startup Repair

But to no avail. It will not let me use my computer in normal mode.
