    Thanks for the ideas. I ran diagnostics on the hard drive and it passed. I don't have a Vista DVD. I bought the HP from ebay a year ago. It didn't come with any disks. Any idea how I can run the repair process?

Run diagnostics on the hard drive (Normally provided either in the F8 or F12 boot menus) and se if you get a failure.

If the drive passes diagnostics, boot to the Vista DVD and run the repair option. (Note: you may have to the Vista repair process 4 or 5 times if there are multiple errors to be resolved)

I have a acer aspire. been having lots of issues. I have now chosen to do a full recovery. Started by hitting alt f-10 at the startup. choosing the first choice to a full clean up restoration. it is now...

Seems like a write delay to your hard drive, a few toshiba and samsung bard drives that are use in acer aspires develop this problem, Since you are still at the Out-Of-Box setup, you should be able to do a check disk or have it scheduled with /f command.

or you can restart you computer holding F8 and select to boot with command, and use CHKDSK /F to check for errors on your hard drive, if there are sector errors, best option is to get a new HDD.

Best of Luck

I have an HP1110n....It acts like it is booting up, but I only see my screen background pic. No icons show up. The disk spins and is doing something, but it won't display ANY icons ! Help !

This happens when Explorer (the file manager - the program that makes all the files visible on the screen) doesn't starts at boot. Press Alt + Ctrl + Del to open Task Manager. Click File, click Run and type explorer. Click OK and the icons and the taskbar will appear. If it doesn't start or it's faulty in any way you will have to reinstall Windows.

My error message is NTLDR is missing press cntrl + alt Del to restart I fixed this a year ago in the bios menu. I forgot how to do this. I don't have my Windows XP CD, but I didnt need this the last...

hello, when it happened on my computer it was the bios that was somehow set to boot from the wrong disk. It happened after I had to reboot after a hang, so it hadn't been shut down properly. Hope this helps!

HP pavilion jDv2915 laptop screen is not showing anything on the screen except for red and blue colours and lines , no matter what keys i press . it sometimes goes to normal when i press cntrl + alt+ del ...

It looks like a virus attack which is eating up your RAM memory since it sometimes comes back to normal on pressing cntrl+alt+del. It should open the task manager. Check what applications & processes are running. Run a thorough virus scan & see if solves the problem. If the laptop cannot be kept on during this scanning process I am afraid you will have to go to a authorized service center.

My computer says disk read error press cntrl alt then nada

In most cases, all recent versions of Windows use Ctrl+Alt+Del to bring up the Tasm Manager. You can't usually use that key combo to restart your PC.
When you did that, was any application highlighted as 'not responding?' If so, that is where you should start looking for problems.
Otherwise, try to post additional information for us here.

On powering on'the screen remains black and the ethernet plug is flickering. no sound from the hard drive

the hard drive could have failed..Try a hard start to see if it will react. Do you get any beeps?? a warning beep or beeps may indicate a hard drive failure. Try to get into C-Mode set up. click alt/cntrl/del as you turn on the set.or alt/cntrl F10. Hard drive failures can happen if ther is to much written to the drive or just a plain 'Crash'.
