Can a computer virus stop my computer from turning on?
This depends on what you mean by “turn on”. Obviously, no virus can harm the physical switch that controls the power to your computer. On most home computers, there’s no way for a virus to affect the power supply either, so power would at least get to the motherboard.A virus could overwrite the motherboard firmware on most modern systems. This would stop the computer from actually doing anything useful, until and unless you re-flashed the firmware. This could not be done from the computer itself, since you’d have no way to boot it up: you’d have to remove the firmware chips from the motherboard, or use special tools to allow you to reprogram them without using the computer to do so. At this level, you’d see the CPU fan and other things turn on, but nothing would appear on a connected screen.At a less extreme level, a virus could overwrite the boot sector on your hard drive, preventing the system from booting. If that happened, you could boot from other media (CD, DVD, USB stick, floppy…) and rewrite the boot sector. You’d get the BIOS boot information, but the OS would never boot up.Now, with poorly designed hardware, it can be possible for software to damage the actual hardware: systems have been made in the past which allowed software to set voltages outside of spec, rapidly change state of components in a way that made them overheat, and so on. In such a case, a virus might be able to actually “fry” components, which could potentially prevent your motherboard from powering on. Manufacturers are more on the lookout for such potential problems now, though, and such a problem would likely only affect specific hardware, limiting how effective the virus could be.
Should I turn off my computer if it's stuck on the loading screen "getting Windows ready don't turn off your computer"?
The old adage “if it’s not working, restart the computer” apparently applies to Windows even when it tells you specifically NOT to turn it off.I got this screen when just trying to reboot my computer (windows 10) and even though the disk light was blinking as though it was up to something, I eventually powered down the machine. It booted back up without issue as though nothing had gone wrong… As others have stated, Windows is pretty resilient these days.In a worst-case scenario if you take this action while it’s actually installing an update, you could run into trouble. Most likely, all you’ll have to do is roll back the update. The chances of causing catastrophic damage are pretty slim.As others have also stated: if it’s really stuck then you don’t have much of a choice. Unless you have a really slow, old computer, it’s hard to imagine being legitimately stuck on this screen for more than about 40 minutes. I couldn’t even wait 15.
My computer will not boot up. What's wrong?
Try this: Restart your computer and when the BIOS is almost done loading begin pressing F8 repeatedly (don't hold it down continuously). Continue pressing F8 until you see a menu appear. Look for an option that looks like "Disable the Automatic Restart on System Failure." Select this and press enter. Your computer will now begin booting. When you see the menu asking what mode you want to boot to, choose "Start Normally." Hopefully now instead of just rebooting, you will see the Blue Screen of Death which is causing your problems. The information on the blue screen of death will help you on your next course of action.
HP Pavilion a6500f not booting up?
You got one of the worst to try to figure out. Do you get any beep codes from the motherboard? That can help you narrow it down. The next things is to unplug everything from the motherboard. See if that point you get beep codes. Then plug the video card back in and see what happens. See if it will tell you no hard drive. Since you have already done the ram thing, I would recommend you either test or replace the power supply. That 250W stands out as having very little overhead. An interment power supply can cause all sorts of weird symptoms. After that it becomes a crap shoot what it could be.
PC not booting, error 26 on motherboard LED.?
Jim is right that your PSU can be dying (ie not producing enough power) and cause issues. Plus Abit in the past has made some really lousy PSUs and yours might be one of them (just saying because you need to keep an open mind when troubleshooting) You didn't post what graphics card you have. And Starcraft 2 is fairly graphics intensive. It's possible you fried your graphics card. If you've got a spare graphics card that you can test drive, try that and see if your system will come up. If you've got a multimeter, test the PSU. What I would do first though is the most simplistic: take out RAM/and reseat; disconnect PSU from MOBO/reconnect; take out graphics card/reseat (you already did this of course). Even try booting up with one RAM chip at a time (this will determine if a chip is bad, or if a RAM slot is bad) Sometimes these can clear up issues. I don't think this will solve your problem but it's worth a shot. IMO you've either got a bad PSU, graphics card or your MOBO is fried. I'm leaing toward the graphics card but that's just a gut feeling. Only further testing will confirm.
What do you do if your computer won't turn on after a power outage?
I think you should start with some of the basics that possibly you might not have considered.Is your computer plugged into a surge protector, and if so, does it have a circuit breaker? If so has it been tripped by a surge when the power was cut off or brought back. If the surge protector doesn't have a breaker, has the surge protector "burnt out" by a surge. Reset the breaker or replace the surge protector. It has done its job.Does your computer's power supply have a breaker? Is it tripped? If so reset it.When you attempt to turn the computer on, does the fan on the power supply turn? If it doesn't there's a chance the power supply isn't working and may need replacing. That could be cured by replacing the power supply or replacing the whole case and power supply.If you have the case open and start the computer does the cooling fan on the CPU run? If it doesn't there may be problems with power to the board. You might be looking at replacing the motherboard, CPU, or both.Do the drives run even if the CPU isn't running? The motherboard, CPU, or other important components may have been harmed by surges.If your computer can not be restarted and you can't figure out what has failed. Remember, in truth your computer is not the computer itself but what is on the hard drives. You can take those drives out and place them in another computer... but you might want a tech to do that who knows what they are doing with regards to re-registering the operating system.If your computer has a built in speaker... I know that might be archaic technology, but... computers have something called a POST test. The POST test will play a series of beeps on start-up and the pattern will tell you what has failed. If all is well, that is what produces the beep you hear when starting a computer.When I last had a problem like this... I came home after an extended absence and there had been a substantial spike on the power-lines due to a power-line tower collapsing into the Fraser River. Even though my electronics were Off, and protected by surge protectors the surge got through to the CPU of one of my desktop computers, gateway router, a printer, and a scanner. I cured the computer problem by transplanting the drives into another computer case that had a working motherboard and CPU in it.I am a bit rusty in my computer repair skills, but I hope some of this may help.
My computer will boot but won't load the homescreen. It only shows a black screen with only the mouse visible. What is the problem?
Please try this.Start tapping immediately on F8 key as soon as you power on your computerKeep tapping until you see pre boot menu optionsTry it one more time if you miss it and go to blank screen with the mouse pointer on itOnce you see those options, select "Safe mode with networking" (You can use arrow keys on your keyboard to select/higlight it and hit "Enter"It will let your computer boot in safe mode (Icon might appear bigger, but that's normal)Go to "Start" > "All programs" > "Accessories" > "System tools" > "Disk cleanup"Hit "Ok"it will scan and bring the list of junk files on your screencheck all the boxes except "Recycle bin" and hit "Ok"It will remove all junk data from your computerRestart the system normallyif it does not work, select "Last Known Good Configuration" from same Pre boot menu options. (It will restore your system to most recent backup, but you might lose some data)or you can try this "Go to Safe mode with networking" and click on "Start"a box will appear underneath "All programs"type "MSCONFIG" and hit "Enter"click on the third tab "Startup", it will come up with all services that load when you boot your computer each timeUncheck all boxes and reboot your computer (it might prompt for it)now if your issue is resolved, check all the boxes one by one, and see which service is causing this issue. uncheck the box which is causing this issue, it might take some time but you can resolve this issue this way.
I just installed my Geforce GT 1030 but now my PC is not booting up even when I plug my old one back in or use my intergrated graphics card what could be wrong?
First off, don’t panic! Your computer is fine.If this had happened to me, the first thing I would do when the PC doesn’t power on is to look inside the case; are there any LED’s on or fans turning? Do you hear any hard drive activity? This would let you know that the power supply is working. If not, check the power supply. Click this link to see a power supply. Check that both ends of the power cord are fully seated. Heck, check your outlet to make sure its working. You never know. Also check that the surge protector is on and working (you are using a surge protector right?). Your power supply may have another switch that allows it to work on different voltages. In the US, make sure this is set to 115V not 220V. (In the US you may see 110,115, or 120V, any of those are ok). That toggle switch is usually between the supply’s power switch and incoming power connector. From there, check all the power connectors inside the case. They click into place so there’s very little chance that you disconnected one but check anyway. They should be fully seated.I’m assuming there is no power to your device but there are all kinds of possibilities. If you see some LEDs or fans turning inside the case, then there is power. If there is power, some of your devices are probably turning on. From here I would check the motherboard to see if it has an onboard video card. There is a possibility that your system reverted to using this video card. Plug your monitor into that and power on to see if that helps.If it’s not working at this point you should at least know if your power supply is working or not. If it’s not working, then you can buy a really nice one for very little. Heck… even if it is working, I always recommend upgrading power supplies. Especially when upgrading video cards. They draw a lot of power. Which is one last thing to check. Your new video card could be over taxing your power supply’s power. Check this link out to estimate your power requirements.Good luck!
