This is similar to my problem I think,? The Dell logo keeps coming up on screen and a white status bar below completes, screen goes blank and then Dell logo comes up again and the whole process repeats. what does "first try loading default value in your bios" mean?

when did you install windows 7? Windows 7 might be to strong for your laptop or you might have to reinstall windows 7.

Immediately after seeing the Dell logo, keep tapping the 'F8' key,
until you see a "menu" (white text over a black background)
giving "startup" options for Windows XP.

Select "Safe Mode" and see if you can start in that mode.
Then, use "System Restore" to go "back" in time, to the most-recent checkpoint (date/time) where your computer _DID_ work.

Restore to that point, and restart.

After the logo flashes, press F8, repeatedly, until a white-over-black "boot menu" is displayed. Choose "Safe Mode", to see if this "minimal" version of Windows will startup successfully.

i think it is a some kind of virus in ur system try going in safe mode and let me know if still problem is there otherwise u have to reset ur OS to get rid of that and do protect ur system with good internet security like pc cillin or norton

restore OS simple procedure pls backup ur data first

When you first turn on the laptop and see the Acer logo screen, hold the ALT key and press the F10 key (you need to do this before the Acer logo disappears).
if there is a window showing in the taskbar blank

the easiest solution would be to re-install windows and hope it is not a hardware problem

You have a virus I hope you have your data backed up. Reformat your hard drive(I assume you have a boot disk)

Hi,
No this should hopefully not come back It can be due to lots of different reasons.
Please make sure to press the option on Fixya that shows that I solved this for you! Appreciate it! :)
Thanks! 

You can either try to reset the BIOS, or have the restore cd fix it for you. By the way, what does the message say?

You should be able to plug in an external (Desktop type) monitor . Look for a connector on the side or back of the laptop. If the external monitor works, you have pretty much diagnosed that you have a LCD problem.
Ron-

I think u need to updrage ur bios and RE-INSTALL UR WINDOWS
