Solved Toshiba satellite won't pass load up screen

May 18, 2015 at 05:29:42
Specs: Windows 8, Unknown
I've had my laptop for about 2 years or so, and I've tried turning it on and it comes up with 'diagnosing your pc' for some time, then after a while, it'll proceed to the normal toshiba leading innovation screen and it will stay on that. I've tried it without and with the battery in, and it still has the same problem

Probably too hopeful but as it's easy to try, do this:
Turn off, disconnect power and remove battery. Hold the Power Off/On button down for at least 20 seconds to discharge the motherboard components. It has been known at odd times to unstick things.

Otherwise let us have your Satellite model number please.

Always pop back and let us know the outcome - thanks

mm... might be a corrupt file or other in the startup sequence.. Might not of course...

Presumably there are no error messages at the time?

Can you try booting into safe-mode (F8 as it starts t boot up)?

Other things to try...

Power down; remove battery.

Remove RAM sticks; clean edge connectors on each stick; wipe edges free of "any" detritus/bits from the cleaning process. Use a soft pencil style eraser for the cleaning process. Re-insert RAM sticks - then remove and re-insert a second time. This re-insertion helps clean the internal connections in the RAM sockets - free of oxides...

Restore power and see if it helps?

One other thing to try...

Download an ISO for Ubuntu (; a Linux variant - it's free.

Burn to a DVD; boot with that DVD. If it boots OK then it has more or less confirmed the actual hardware (apart from the hard drive) is OK. It loads into RAM only and ends up on a windows style desktop. Once it has booted - you can access the hard drive...; and presuming you can, I would immediately copy/save all my personal files etc. to external storage; typically dvd but to an external hard drive too is nice(r). Knowing files are safe elsewhere means you can more comfortably set about resolving the problem as posted...; presuming it's not simply a RAM contacts issue.

If you cannot access the hard drive contents (via ubuntu boot up)... then it may suggest an issue with the drive; but I seriously doubt that is the case here.

Safe-mode may help; failing which possibly you have acquired a pest or three and need to scan for those

Kaspersky Rescue Disk (freebie ISO) burn to a dvd; boot with that DVD. It will load into RAM only (it's based on Linux again), then go online to update itself. After-which it will scan the system fully and deal with anything it finds.... (A link to How ToGeek which has detailed info on using the utility; similar to that at Kaspersky support).

Last resort (?) a repair routine of sorts; but ideally avoiding the dreaded factory reset/restore routine if at all possible. And if going anywhere near any kind of repair... first ensure files are safely copied elsewhere - as above.

If you can get into safe-mode there is very safe and effective free utility which will resolve all manner of issues for win7/8 etc... - is where to find it; but it does require a minimal windows boot to work - safe-mode being the recommended...

Yes, it would be useful to try to boot into Safe Mode but the old F8 doesn't work on Win 8. This is the procedure:
Worth looking at but from what you've said it doesn't boot far enough to do this.
