Overheating Or Ram Issue

1261 Views 2 Replies 2 Participants Last post by  schusterjo
I have a Toshiba laptop with windows XP and I have a problem with it randomly turning off. I don't know if it's a overheating issue or if I'm using to much ram or what, I dunno.

Here's the problem: My computer randomly shuts off while I'm using it. Sometimes it'll shut off when I have a lot of programs running, sometimes it'll shut off when I have just a few running. It's been a problem for a while now, and recently I just downloaded WoW, and every time I try to play it, It'll let me play any where from 10-30 mins, but the comp always shuts off on me no matter what. I downloaded a couple programs to try and diagnose the problem, but I'm not getting anywhere. I Dl'ed PC Wizard to see my temperatures and it will only show my CPU temp which is at an average of 40c (MIN=29C MAX=51C). I also Dl'ed speedfan and it also only shows my CPU temp, and says the overall fitness for the drive is 98% and the overall performance for the drive is 100%. I can't seem to find anything about the fan settings or temp, and I'm not that tech savvy, so I don't know what to do. I need some help. Does anyone know what the problem can be? Any help/advice would be appreciated.

Oh, and when I first start up my comp around 50% or more of my ram is being used, I tried using programs to free up unused ram, but my comp still shuts off while playing games or having a lot of apps running. I need to figure whether its my ram causing my comp to shut off or if its overheating.

(of coarse ATX PS will not apply but the rest will)

Microsoft says whenever a computer freezes or reboots (crashes) you need to run chkdsk
Start, my computer, right click on your hard drive, select properties, select tools, error checking click "check now"(chkdsk).
(General maintenance can save alot of headaches, see link below for general maintenance)

Hard drive
Download the diagnostic tool and check your hard drive

When your CPU overheats, it will usually cause your computer to reboot. Video card overheating causes artifacts to appear on your screen, and usually wont cause reboots.


Enter BIOS upon powering on your computer. Most BIOs have a hardware monitor. Use this to check your temperatures and fan speeds.

There is also hardware monitoring software that can check your temperatures from Windows. Your hardware monitoring software should have come with your motherboard. If you have no monitoring software, you can go to and get PC Wizard. PC Wizard is an easy to use program that will let you know what kind of temperatures you have, and what your fan speeds are at.


CPU overheating is usually caused by a failing CPU fan or improperly applied thermal paste. Fortunately, these 2 causes are easy to fix. If the CPU fan is dead, buy a new one and install it. If the thermal paste is improperly applied, remove the old paste off and apply new paste.

Another method is to take a house fan and open the case blowing the fan on high into the case.
if this helps we know its heat.
Goto radio shack buy a can of PCB cleaner (printed circuit board) unplug computer for an hour, open case spray everything starting from top working down to the bottom make sure you get the cpu heatsink and video card really goods.

Power Supply (PSU) Problems


It is important to have a functioning, proper size of PSU for your computer. Having an underpowered or failing PSU is often the cause for random reboots. To get an estimate of how powerful a PSU, use this PSU calculator and add about 50W to the minimum power the calculator gives you.


The easiest and best way to diagnose a faulty PSU is to swap it with another one that you know is in good working order.

PSUs just die after a while.



Faulty RAM and RAM slots can cause random errors/reboots.


The best way to determine if RAM is your problem is to run your computer with one stick at a time, and see if the problem occurs for either stick. This obviously doesn't apply if you only have one stick to begin with Also, try the RAM in different slots. The actual slots might be causing RAM-failing like problems. The next step is to run memtest86 to determine if you have faulty RAM.

I run this daily

SpywareBlaster 3.5.1
I update once a week (keeps bad pages with known malware that cold cause damage from being displayed.)

Spybot - Search & Destroy
Daily or every other day

This is one I only use once a week or month lol but good to have

AVG Anti-Spyware
In order to get full use of this one you have to buy it but has a free trial. Good program to have and run before you run Hijackthis.

Download and update (update is very important before you scan) boot into safe mode (You do not need to boot into safe mode every time to run programs. Some malware cannot be fully removed or detected unless you are in Safemode, This is why I recommend running it the first time in safe mode then perhaps once a month in safe mode)

With some computers if you press and hold a key as the computer is booting you will get a stuck key message. If this occurs, instead of pressing and holding the "F8 key", tap the "F8 key" continuously until you get the startup menu.

Scan the computer,

Boot backup into Normal mode, download
CodeStuff Starter manage your startup programs

Disable all startup programs that you "do not" need running at startup.
