I built my computer 8 months ago. 6 months later, the mouse pointer started lagging so bad it was unusable. I tried some fixes but nothing really helped. The next day, my computer didn't work. POST says it's the graphics card. Okay, I got a new one. It arrived today and I put it in. Nothing has changed. The fans on the old one worked, so it had power. Did I misread my beeps or do something else wrong. I know enough to build a pc, but not enough to troubleshoot it.
This is my motherboard. It doesn't have onboard graphics.
This is the old graphics card.
This is the new one.
Help!
As requested: 1 long beep, 3 short. No unusual flashing.
It powers on fine and everything appears to be working inside, but it does the beeps and doesn't show anything on the monitor.
This is the power supply.
Would you mind sharing more on what's happening? Does it refuse to power on anymore? Do you get some sort of error message? What kind of power supply do you have?
Agreed, usually for troubleshooting you strip it down to the bare essentials if it isn't booting. 1 stick of ram, no hard drive, some type of graphics. Getting it as simple as possible so you are removing variables.
I've seen mice that prevent a computer from posting, so sometimes it's really weird causes.
Honestly, I'm wondering at this point if I shouldn't just get another motherboard. This one doesn't have onboard graphics, so I have no way to do what you're saying. My mouse is Bluetooth so it's not even in the same room anymore. I only have access to a laptop now, so I can't even put the hardware in a different computer to test it.
I was actually going to ask if you had another one. Sometimes it isn't the card, it is the slot or a controller. If you have access to another board you can rule that out.
I've basically come to the conclusion that a new motherboard is necessary. Should I assume this was a one off and get the same one, or try a different one?
Your current might be under warranty. I would check that first. You don't need to change it if you are happy with the theoretical limits of it.
It powers on fine. The only error is post that I can see because I can't use the monitor to see anything else. There is no onboard graphics so the monitor isn't usable.
Power supply I put in the post, it's 750W modular.
Did you use two seperate PSU cables for each 8 pin on the GPU?
It's only got 1. I'd need a second power supply for a second cord. My very first pc build had interchangeable cords, but this power supply doesn't. The fans on the cards work, so it's definitely getting power.
