Toshiba M105-S322 Locks Up

I've got a Toshiba M105-S322 laptop that freezes at random requiring a soft reboot. Sometimes it'll happen right after boot, sometimes it'll go for hours without a hitch. I'd say it's software related but I'm seeing where the system seems to have trouble consistently seeing the memory, sometimes it'll read 512MB, sometimes it'll see 1GB. I'm going to go ahead and replace the memory, but is there some way to find out if it's the MB before I do so? If it's a bad MB, I'll probably just replace the computer. Any suggestions would be appreciated.

    I've already pulled both sticks of memory and made sure they were properly seated. This last time, it was reporting 512MB, I pulled one out and rebooted, it still reported 512MB (so I assumed that the one I pulled was the bad one). I replaced it and the system saw 1GB, but the system still locked within a few minutes. It seems to recognize both or not at random.

    I've also tried the software route, I've gone back and reinstalled from the Toshiba system backup CD and it didn't solve the problem.

    Yes, I did format the drive when I reinstalled and I haven't replaced the memory yet but I'll buy 2 new identical sticks when I do. I'm going to try switching out one of the current sticks with another that I have here, just to see if it helps with the problem.

    I finally got around to switching out the memory and it didn't fix the problem at all. I switched the existing memory between the two slots, switched out with new memory one stick at a time, no go. It still locks up.

    My next step is to strip it down to the CPU and make sure it's solidly in place. Unfortunately, there are a couple of stripped screws that I'll have to drill out before I can open up the case. I figure it's got to be a hardware problem, the system doesn't even boot up most of the time, it might get to the BIOS but not necessarily.

    Nope, didn't solve the problem. I stripped the laptop all the way down, pulled the CPU and made sure everything was perfectly connected. Regreased the CPU properly with Arctic Silver 5 (it looked pretty spotty when I pulled it), reassembled the whole laptop and it's still having the same problem. It booted up immediately when I tested it, I let it sit for a couple hours and now... won't boot at all. You turn the power on, it's on for about 2 seconds then shuts off again. It's not even getting to POST.

    Guest, your problem is definitely software related, you should be able to solve it by repairing or re-installing Windows with the original installation disk.

You need to follow some simple steps to boost up your speed. Before using the 3rd party utilities I suggest you to start with windows own utilities. Perform disk clean up,

Start> All Programs > Accessories > System Tools > Disk Clean up

Reduce the quantity of startup programs simple type MSCONFIG after open the Run option and enter. uncheck the non essential applications (You can consider non essential all softwares aside hotkey utility and antivirus software). After click on apply and OK restart prompt will appear. "Don't Restart"

Go to My Computer, Right click on C drive and choose "Properties" click the Tools tab and click on the check now button in Disk error checking area. Check both of the boxes when it prompt. And click on OK. It will inform you that system unable to check as its in use therefore it will start when you restart computer. It will perform 5 steps error checking. It might take up to 1 hour.

Once computer start it will be definitely faster. however you have still many ways to choose better performance over some value added features. Like you can choose best performance instead of best appearance at performance settings area. Also you can disable System Restore feature this will increase performance and speed while feature will be not available.

Please post your questions if further assistance needed.

Good Luck.

Remove the memory, maybe you can see the capacity of the memory. I guess you have two memory in the laptop 2 -512 mb. sometimes the system recognize to memory and sometimes only one memory can be recognize.

Maybe you can fix it by your self. try to fix well the memory and start the system and see if the two memory was recognize. if not then you should replace either of the two memory or replace it with one 1GB memory capacity.

hope this help.

May be dust. I just took apart one and found the fan blocked by compacted dust. It had symptoms similar to yours and now works fine. It might be possible just to take a vacuum to the fan intake on the bottom and just **** the dust back out.

You have lost your backlight which is a thin long bulb built into the bottom of the screen itself. You have the option of getting the backlight by itself and rebuilding the screen or buying a new screen assembly and changing that out. Below is the service guide to change the screen.

Toshiba Locks up

The reason your laptop is rebooting is due to a faulty RAM memory card. Replace your Ram Card(s) and all should be fine. Toshiba's are common for faulting due to damaged sectors in the ram cards
