G620 boot problem


My eMachines g620 fails to boot almost every time I turn the power on. It hangs before loading windows Vista, just a black screen hangs... It probably doesn't load up the boot files, 'cause hitting F5 or F8 on boot-up won't do anything. With patience and occasionally several hours of time, I manage to get it powered on by turning the laptop on and off. If I try to restart Windows, it powers off and it all starts again. I've replaced the battery, no use. Though, there's something fishy 'cause if I try to power the device on without power supply cord, the power led only flashes once and laptop turns off... With cord, I'm yet able to unplug it immediately after power-on. Every time I press the power on, the system wakes and I'm able to enter BIOS and the fans are on. After exitting BIOS the system powers off, no reboot. If I manage to get the system started, everything works perfectly. Because of this annoying problem I have to keep my laptop on 24/7, but sometimes I really should reboot at least for updates... Is the cause in Vista, mobo, hard drive or what?? I really appreciate your help!!

    I was suspectin' the hard drive also, but how it could cause an improper restart? Is it possible to re-write the boot sector/boot files?
    And about that RAM matter... Why is the system working properly after succesful boot? This is a boot-up issue only..!

    This is simply a problem of Hard disk. Try replacing it. You can reload vista before replacing it.

    yes of course it may be a hard disk problem too... yes you can rewrite the boot files...

    or repair them using

    fixmbr command and other commands from the fdisk utility.

Recent upgrade to Win 10. Boots to Windows logo and goes to white screen. Abel to F12 and ran diagnostics and all clean. Not sure what else to try

There have been problems with some DELL computers when people have upgraded to W10. \
I am not familiar with DELL but there should be a facility on your computer to reset the software to original factory settings. When you run this though you will lose anything saved to your computer and any software you have loaded such as security software.
I would try this and don't upgrade to W10 again.

If unsure what to do I think there is DELL specific forum where you can get some help.

Restore laptop

If your PC has a recovery partition:
Turn it off.
Before Windows logo appears (after it turns on) keeps pressing F8.
Then you should see Do a system restore?
Keep pressing F8. Then follow what your computer will give you.

If you have a DVD/CD drive and a recovery (reinstall too) disk:
Insert it in.
Turn off your PC.
Turn it on again.
Then keep pressing F12 or F8 (any works).
After that you should see a boot-menu.
Select the option which says to boot from the CD/DVD drive.
Then follow the instructions.

Windows 7 upgraded to 8, crashed, restarted windows 8, touch screen will not work now, did before, any clues, thanks

There is no way to know where the upgrade failed so trying to repair the upgrade is not an option. I am sure that it is the reason why your touchscreen doesn't work. Try to restart the upgrade process. If that doesn't work, use Lenovo's recovery image or disk to get it back to Windows 7 and upgrade to 8 again.
Make sure that your computer is on AC power, has plenty of free disk space and all non-essential peripherals are disconnected to avoid another upgrade failure.
If it still fails your download of Windows 8 might be corrupted or your memory is creating errors.
I hope this helps, Windows 8 is so much better for touchscreens!
Good luck!

I have on my emachines G620 videocard GeForce 9100m G,can i replace it for some better videocard?

No, that video chip is an integrated one - part of the northbridge chip - so it cannot be replaced . Also there are no slots for video cards inside your laptop so no way to add another one.
