Computer won't start-up

So earlier today in the afternoon I turned off the monitor of my computer like I usually would but when I came back and tried to use the computer tonight the computer didn't seem to be "detected". Turning the monitor on and off displays a message that it cannot find a source, I checked the cables and they are all connected. I also have an internet phone line that runs through the computer and in order for it to function the computer needs to be on, but even when the computer light is on (with a solid activity light) the phone doesn't work.

What this all suggests to me is that a possible hardware failure occurred, but I have no idea exactly why it'll turn on but not even attempt to load anything.

Any ideas would be greatly appreciated! Thanks.

Sounds like your power supply has died. I suggest that you should check into that first and replace if needed. Some power supplies reset them selves. Also check to make sure that the power switch on the back of the computer wasn't accidentally turned off. If that doesn't work, then you can start isolating other components. Thermaltake makes some great power supplies!

I think that I wasn't clear earlier- the computer turns on but doesn't do anything. I can't open any of the disc drives etc, but today I was fooling around with it again and noticed that the fans are running. While it is technically "on" something is wrong, the monitor doesn't detect that the computer is on, and the internet phone doesn't either.

I'd still vote for the PSU. If it is not getting enough juice to your motherboard or peripheral hardware, your fans or selected parts might work, but nothing else. Since your power supply also connects directly to your disk drives, and they do not open, they aren't getting power. So I stand with this option to look at first. (Y)

I agree with Barney on this one. (Y)

Okay so the power supply came. I ordered the exact same one that the computer came with so I know that it's not because of an aged power supply or insufficient power.

The humming noise that the computer was making is now gone and now it runs quietly but that's all it does. Windows doesn't load up (to my knowledge) because the monitor doesn't recognize that the computer is turned on still.

vIsi0n,

Did you have any huge power spikes around that time? If you KNOW your computer is actually booting up, and you still get no video then it could be a monitor or video card issue.

If you take out all your RAM and you get no POST beeps, then that could be a very bad sign. Ive had 3 computers where the CPU fried/went bad, and the computer would turn on and all the fans would go... but nothing on the screen. This was happening because the pins were still making a connection, allowing the computer to power, but then couldn't go any further.

This topic is now closed to further replies.

    • Microsoft brings Planner Agent to all Microsoft 365 Copilot users

      By Ivan Jenic · Posted

      Microsoft brings Planner Agent to all Microsoft 365 Copilot users by Ivan Jenic Image: Microsoft Microsoft has announced that Planner Agent in Microsoft 365 Copilot is now generally available to all users with a Microsoft 365 Copilot license. Planner Agent is the latest addition in the string of AI features that Microsoft is implementing across virtually all of its products. The agent lets you manage tasks through natural language prompts directly inside Microsoft 365 Copilot. You can create and update tasks, check priorities, and get insights about current entries without leaving the chat interface. The general availability release comes with a handful of new additions on top of what was available during the initial rollout. A new plan picker lets you search and filter your plans by name, then update task names, statuses, due dates, or priorities through the agent. There's also a goals bucket now, which lets you group tasks under specific goals. This builds on the Goals view, a feature that was introduced as part of the broader Planner refresh that rolled out earlier. Image: Microsoft | Planner Agent in Microsoft 365 Copilot All AI-generated plans and tasks are created in draft mode by default, so you can review and approve changes before anything goes through. This is actually a thoughtful safety feature, because trusting AI to handle all your tasks without a human in the loop is usually a recipe for disaster. Having tasks initially saved as drafts is the best possible middle ground. Microsoft also says that not all tasks are executed equally. Simple tasks get processed quickly, while more complex ones, like building a plan from a Word, Excel, or PowerPoint file, are handed to a more capable model. Microsoft says this approach delivers the best performance, but it could also help with usage management, as you won't have to waste tokens on performing simple tasks. Planner Agent is available now across Teams, Loop, SharePoint, and other Microsoft 365 apps for anyone on a Microsoft 365 Copilot subscription.

      Trillion dollar Microsoft has to reduce spending by hurting more people. Good job Microsoft. Good Job Asha.

      That's a shame. The big Xbox reset when Phil and Sarah left and then Asha came on and brought a new team of executives, and all the layoffs last year and saying that the ABK merger wouldn't result in redundancies I am surprised they are calling for yet another reset and yet more layoffs.
