S3842 uk FREEZES ON BOOT every time have to switch off. on 3rd or 4th attempt works fine. any new software that requires reboot - it does this without a problem. started 2 months ago with original Vista loaded - thought Win 7 upgrade would cure but no! since then done clean (i think?) reinstall of Win 7 from upgrade CD - no Vista disc so then tried to install XP but get blue screen of death. help!

The starter windings may be shorted, that would explain the draw, if the starter is ok then the engine has really got a problem.

most likely the 4th clutches are bad and its down shifting into 3rd. time for new transmission.

If you have already replaced the screen...
Common problem when replacing equipment on laptops is that the "cable" goes into a flat housing that requires you to lift a little white "gate" then insert the cable and put the "gate" back down. Problems usually occur when snapping the "gate" back down. Pull the cable back out and be sure to lift the gate insert the cable and then put the "gate" back down. Once done give it a light tug and it should hold very firm and not move at all

Power the machine down. Press the power button, then immediately press and continue to hold the shift key. This will perform a "safe boot," skipping any of the boot-time software you may have added to your machine. If it still fails to boot, more involved diagnostics are required.

change the ram memory ...this issues appear when the ram memory is not functional like it should..if you have a way to borrow some just to try ..you will make an ideea
If you have more than one boards in the laptop..remove one by one ..and try to boot with the other/s until you locate the one with problem..

It sounds like something else may be causing an issue. Since so many replacements have been made, but the problem persists I would recommend getting a technician out to look at the problem to make sure everything else is fine.

for your first boot cd/dvd rom, 2nd boot hdd is it serial ide or sata, then you can disable the 3rd boot device, if it freezes and does not save reboot your pc in some motherboard there is key to press for you choose which device to boot first if you find the key sometimes its f12 or f10 when press this it will promt which device to boot first then choose which of those devices you want to boot first

I would first attempt to reinstall the software from the install cd. Your Toshiba support page is recomending a new BIOS upgrade. See below:

well you have no choice but to turn it off...hopefullly when you reboot the machine it will attempt to reinstall the firmware..usually that is what the unit does. if it freezes again at 100percent it very well could be the 3rd partion sector of your SATA drive....ive seen this before.

At first guess, I'd say you have a driver problem. Reboot the machine in safe mode, leaving the switch in the "ON" position. (F8 at startup for safe mode).

Log into the machine, and go to Device Manager. Uninstall/remove the wifi adapter.

Reboot.

Upon reboot, the system will attempt to reinstall the adapter, but you should not have a blue screen. If you have the original drivers, point Windows to them. You don't want Windows to use the "existing" drivers, because that's where the problem occurred.

Once the good drivers are installed, you should be back in business :)

Hope this helps - remember to rate!
