My Satellite L755-S5256 will not boot past the Toshiba screen. It keeps cycling over and over. I tried pressing F12 and selecting the HDD to boot from, and also tried selecting Recovery, but it wont boot. Please help

Forgot to add that the laptop was previously working fine. Last thing was Norton picking up something and I clicked to remove it, and thats when it immediately rebooted and was stuck in this loop. Also of note is that I had 8G of mem and now bios only shows 4G.

Try a system reset. Power off the laptop, unplug the AC from the unit, remove the battery, press and hold down the power button for 30 seconds, replace the battery and AC, power on, if you see the Toshiba logo, press the 'F2' key to enter the BIOS Setup, in setup press 'F9' to load setup defaults, press 'F10' to save and exit, and then boot into Windows.

Your model's specifications show that it came with only 4GB of RAM, and that both slots were occupied. So, where did you get the other RAM from? Toshiba notebooks are very finicky about the RAM they use. So, you should only use the Toshiba supplied/approved RAM, or the best compatible modules Kingston Memory offers.
If the reset doesn't work, and you still have your original RAM modules, you could try putting those back in and see if it helps at all.
Please let us know what happens. Good luck.

Please try to give as many details as possible. Were you able to enter the BIOS setup by pressing F2? If so, in BIOS setup were you able to press F9 to load setup defaults, and F10 to save and exit?
As soon as you see the Toshiba logo keep repeatedly pressing the F8 key and see if you are able to get into the Advanced Windows Options Menu. If so, can you start in Safe Mode?

Hello, I have the same problem with the same laptop. Tried resetting the bios setup to defaults and it did not help. Tried pressing the F8 button and no windows setup popped up. The laptop was working well and suddenly it will not boot. Really appreciate your help.

Wow! A brain surgeon? Really? And I was just making jokes about changing keyboards not being brain surgery.
Do you have a Windows 7 64bit Emergency Repair Disk (ERD)? If not, download this ERD disk image on another computer and burn it to disk:
Insert the disk into your L755-S5256's DVD/CD drive and reboot, as soon as you see the Toshiba logo press F12 to enter the Boot Sequence menu, use the up/down arrow keys to select CD/DVD Optical Disk Drive, hit Enter to try and boot off this disk.
Are you able to boot up? If so, you should wind up in the Windows Recovery Environment (WinRE) at the System Recovery Options menu:
Then try a Startup Repair and a System Restore from the Windows Recovery Environment.
Let us know how it goes. Good luck.

Hello, I burnt the file on a CD. Tried what you said but it will not boot and the screen keeps flashing on and off with Toshiba screen. Is there another that needs to be added to the cd to make it bootable?

Can you use the disk to boot up on another computer?

Yes I tried it on another laptop and the other laptop does not boot up either. I even opened the windows repair file that you had me download that was in ISO format and burnt the content of it into another cd. It still wont boot up.

Time to take to a professional for a diagnostic & estimate.
Good luck. If you get it worked out, and get a chance, let us know what it was.

I made the repair disk and will try it, just in case it doesn't work, where might I obtain a System Restoration disk? One did not come with my laptop when I purchased it...
