Me and my brother had the same problem we just moved the memory module from one bank to the other but this means the motherboard is on the way out and the memory slot on the board is goosed, so will have to replace it eventually if this is what your problem is for freezing but in the meantime works just fine, hope this helps

Be Happy

Trying booting up in the Safe Mode (with Networking).

This way you can distinguish between hardware or software issues.
If your pc stops freezing on Safe Mode, then it is software issue you have.
If your pc keeps freezing on Safe mode as well, then it is a hardware problem and possibly something with your motherboard.

Hello there dear sad computer failed owner,

Here are a few things you can do to fix your computer on your own. I am not a computer expert but I am delighted to say that with my basic computer knowledge I can say that I can take apart my Toshiba M45-S331 in minutes and find most of the problems.
The only tools you will need is a small philips.
Now, if your computer freezes up (I had the same problem), I would
start from the first tip (easier & faster to harder) and follow through till the problem is gone.

#0 Try the Recovery cd
#1 Spray compressed air in the fan just in case it is clogged.
#2 Use a different power adapter if available.
#3 Remove the heatsink (In the right-side, bottom of the laptop) one screw to open the compartment and three more to remove the sink and spray canned air.
#4 Confirm that the memory card is sitting good in there and/or replace the memory card (My M45's #1 issue)
#5 Replace the fan (My M45's #2 issue)
#6 Your motherboard could be faulty (Better check this one with an expert)
#7 Make sure the Hard Drive, memory card and wireless card are correctly installed (Sounds stupid but you never know)

Hope you succeed.

Sounds like your PSU or battery is not supplying enough voltage. The PSU is the AC transformer. Beneath it, there will be some specs to indicate what voltage rating it has. Get a VTVM and check the voltage at the end that goes into laptop (if you do not know what a VTVM is, then already we are at a point where you should seek a repairman for this cheap quick test). If voltage is below the voltage rating, the PSU is definitely bad. If it is JUST barely at the rating -or fluctuating, then you must check it under LOAD to be sure. Not so easy. You can try an automotive direction indicator bulb for voltage ratings between 12-19 volts or so. Higher voltages wioll need an appropriately higher device to test, and you must also not exceed the amperage rating.

Then once you have the PSU driving some load, measure the voltage. If it has dropped below the rating, the PSU is bad.

Also, shut off the laptop, remove PSU connector and remove battery. Now reconnect PSU and start laptop. If the problem is GONE, it is the battery that is bad. It has a short or a dead cell that is consuming all the PSU power, leaving the laptop starved for enough voltage to cool the system.

only measuring the voltage can say for sure. freezing gauges could occur under higher or lower than design voltage. easy to check. i like to test drive with a voltmeter in the (lighter) power socket so i can see changes while i test drive.

Sounds like your system needs a anti-virus issue. Restart the system hitting the F8 key as it begins to start until it the system gives you option of how to start the system scroll down to "LAST GOOD CONFIGURATION THAT WORKED" click on that. The system should start as normal, once it has go to your anti-virus and run that - then go and do a system restore to a point before it began having the freezing problem. This usually comes from movie sites with pop ups do not click on pop up only go to sites you initiate.

Tecra 8100 Freezes shortly after Windows comes up

Go into your hard disk utility and defragment your file. When the computer writes to your hard disk over time these files no longer are sequential as they were in the beginning. This is one solution, also you can do a disk recovery using your original disk or by pressing F10 as it boots up. Be sure and do a good check for viruses as well. The symptom you are describing sounds alot like a virus that is slowing your system down more and more. Good luck.

Sounds like there is a program trying to run that is locking up your computer. what was the last program you installed?

If you know, when booting up, press F8 and go into safe mode. Uninstall that program. then reboot normally.

If this does not work, you may have a virus.

Lets start with this first though.

Hoshizaki Ice Machine Model KM-500MAF

(Quated From Hoshizaki Technical Bulletin)
An alarm code of 3 beeps
every 3 seconds means that the control board has shut
down on the 60 minute freeze cycle back up timer.

The “E” control board has a 60 minute timer that starts at
the beginning of the freeze cycle. If the float switch fails
to open and start the next harvest within 60 minutes, the
board will automatically start the harvest cycle. If this
occurs in two consecutive cycles, the control board will
shut the unit down on the manual reset, freeze cycle
back- up timer. The yellow fault LED marked “60 min.”
will illuminate. This safety is designed to help prevent a
freeze up of the evaporator.

Once you have identified the 60 minute alarm, there are
several things to check. Reset the alarm by depressing
the white reset button to the right of the fault LED’s.
This must be done with the power “ON”. Now check the
float switch to see if it is stuck in the up position. A stuck
float can occur if scale is present on the reed switch
shaft inside the housing. To check it, drain the water
reservoir, unplug the black float switch connector (K5)
from the control board and check it with an ohm meter
for a closed switch (zero ohms). If the float switch is
sticking, clean it with ice machine cleaner or replace it as
An inlet water valve which is slowly leaking by during the
freeze cycle can cause a 60 minute alarm. If the inlet
water valve is stuck wide open, it is unlikely that any ice
will form on the evaporator. Check for a slow leak by
allowing the unit to cycle into the freeze cycle and
disconnecting the hose at the outlet of the water valve. If
water leaks by during the freeze cycle, the water valve
diaphragm is likely damaged or the small diaphragm bleed
port is clogged with scale. Clean the bleed port or replace
the diaphragm or entire water valve as necessary.

(I Recommend to get a refrigeration tech for this part).

Another possibility is a refrigeration system problem. You
should use normal refrigeration diagnosis procedures to
check for one of these problems. If the thermostatic
expansion valve is not feeding properly or the refrigerant
charge is low, the evaporator will not form ice as it should
and a long freeze cycle will occur. This could also be the
result of the hot gas valve not closing completely during
the freeze cycle or if the compressor valves are weak or
inefficient. An inefficient compressor however, will
usually show up first on the KM model through a longer
than normal harvest cycle. This is because of cooler
than normal discharge gas. Use proper refrigeration
practices to repair a refrigeration system problem.
While these are not the only reasons for a 60 minute
freeze cycle, they are the most common and should be
checked to resolve a 3 beep/yellow fault LED alarm.
