My Acer Aspire 5315-2153 will boot up. It shut

VIRUS. a big bad one. Try the restore discs or a bootable USB. you made a bootable restore right? RIGHT?

check bios at boot for any 'hard disk detection' options to see if the drive is actually getting power and being recognized by the system. If it is, it may likely be the boot record, which will require a reload or restore.

You do not say what OS you are running. You could try F12 at bootup to see if you can get to the boot manager that way.

this seems like a software issue . if you can not run your system but ift works fine in safe mode try to run a system restore from factory disks and see where that gets you,

it seems u have done every try.So now i recommend u too backup ur necessary files and install a fresh copy of windows via cd.
I recommend u to use xp or windows 7.

Insert your restore CD if errors are found and not fixed by the checkdisk function listed above. Turn your computer off and then back on. You'll beasked to hit any button to boot from your CD; press any key. You will then beasked if you want to install a fresh version of your OS or "Repair" acurrent copy. Choose the "Repair" option.

Disconnect any external devices, plug in your power to a A/C outlet, re-install the restoration disk and start over.
Check your BIOS again to make sure the CD is the first boot drive. You may not be saving the BIOS change or the restore disk may not be bootable.
You can check the restore disk on any PC or laptop.
Also you may have a restoration partation on the hard disk. Get you docs. and check.

when u power up the computer press F8 key then enter in safe mode.
If u can enter in safe mode u can again start rrestoration or u HAVE TO REPAIR winxp with boot able disk.
