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

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.

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.

My new HP notebook won't turn on. I've had it for one month. There is a light on the side where it is plugged in, but it won't turn on

Unplug the AC adaptor. Remove the battery. Hold down the start button for 1 minute. Replace the battery and plug in the AC adapter. The computer should reboot.

When on the internet, computer freezes up frequently, not responding, why? I ran diagnostics and when testing the hard drive, there is an error code. OFOO:0244 msg: block 26318316, I don't know if this...

Check to see if your laptops overheating. Check to see if the fan/heatsink assembly is clogged..

Run chkdsk /r from your command prompt, let it reboot to run..

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.
