Open up the PC and reseat any connector and modules a few times. Concentrate on the RAM and Video Card if it has one, removing and reinserting them at least 5 times.

This process cleans all the contacts and ensures that everything is properly plugged in.

If it still doesn't work then there are a few possibilities. The three components that have most likely failed are power supply, RAM (memory), or motherboard. If nothing happens, no lights or beeps, then it's probably the power supply. If the machines turns on but doesn't do anything then it's most likely the motherboard. If it tries to boot up but stops and gets stuck or if it stops at different times then the memory is most likely faulty.

Blank screen after boot splash screen


Hi.

After you see the press Del and F12 message repeatedly tap the F8 key, see if that gets to the advanced boot menu, if it does select "Repair my Computer" from the list, and then follow the prompts. Have your Win 7 disk ready just in case you need it.

Let me know how you get on and good luck!!

Once I turn on the laptop it stays stuck on the LG Splash screen, I press F2 to enter bios setup but it just stays on the splash screen, and nothing progresses, I can't do anything,


I've seen issues like this with a bad hard drive. When entering the bios it queries the hard drive first and it's got issues it can hang it up like this. If you have a spare try that. You can try to boot it without a hard drive to see if it gets past this. Some computers won't boot without a hd though. If you've got another computer you can look around online to make a flash drive bootable and use that instead of your hard drive. Lastly, get a new hd.

Monitor stays in sleep mode?


when you disconnect the monitor from the PC do you see the self test appear on the screen? if you do then the monitor is working fine.
the issue is most likely that the computer's screen resolution is too high and your monitor cannot output that resolution , so it stays a blank screen or in 'sleep' mode as you described.
youd need to go into either Safe Mode when booting the system or find another monitor preferably a newer model to connect your computer to and decrease the resolution before connecting your monitor.

Power on emachine T6420 and moniter is blank. The moniter soon loses contact with the computer. The fan run and power is OK there is no beep code.


If you mean after the computer performs the self test the screen goes blank and stays blank, eventually turning off you are having a hard drive problem. When the computer boots you should see an E-Machines logo and/or a self test on the screen. That is done by the motherboard as part of every boot up. After that the motherboard passes control to your boot device and loads your operating system. If your computer stops booting at that point, your boot device is not working properly. That could be caused by many things - virus, hardware failure, power outage. If you really mean you see nothing at all on the screen when you press the power button your computer simply is not working at all. Open the case, blow all the dust out of it and reseat all components you can, then try again.

Monitor displays breifly then goes to blank screen


If tried the monitor on two other computers with the same result -- definitly your monitor is faulty. Take it to the repair shop. To make double sure, run your computer with another monitor. If everything is fine now; you can blame the monitor.

Computer not letting me open or close anything.


In some cases, the motherboard causes the screen to go blank and not load any program. Thats what happened to my HP Laptop. I called the company and explained them that nothing will load up and the screen went blank and they replaced the Motherboard.

So In tis case I think You need a new Motherboard.

Thank You and have a Great Day!!!!!
