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.
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.
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.
Have you try cleaning RAMs and GPU?
I changed my PSU and it wouldn't boot into bios with a led on the boot. End up just cleaning the connector of each RAM stick and it work like a charm.
Pretty sure you looked it up, but yeah the manual says its "No VGA detected". Hmm maybe that PCIE slot is messed up? Try another slot? Do you have an iGPU? Does that work?
A few things, your CPU is the component which would host the on-board graphics not the motherboard. Intel CPUs that do not have an -F in their model number have on-board graphics (11400 or 11600K for example) so knowing what model you have may clarify this.
I assume that the system is no longer able to POST even with the new graphics card installed? This likely indicates that it is an issue with the motherboard itself potentially having a damaged connection to the GPU (just a guess). It would also be helpful if you have a recording of the beeps to help you confirm the pattern.
