My PC keeps shutting down at random moments.
It shuts down a lot when i turn it on, it will almost load up and it will shut down again, (Shut down as in all the power just goes and its off or it just restarts it self) and it can do it 3 or 4 times in a row.

If i play games ill just get started and about 5 minutes in it will just shut down.

If i try use a Virus scan, spybot scan or Ad-aware scan it shuts down.

If i use my burner it shuts down.

I cant install updates to things(like windows updates) or it shuts down

Even if i use google earth i can expect it to shut down:eek:

And when browsing the internet it has shut down on me aswell!

I dont know if its hardwear or a virus/bot/something created by the devil:(

I have removed the Graphic cars, The CPU and Fan, Ram Sticks, sound card and cleaned them all up and it still happens.
I have tryed taking out a ram stick thinking i might have a faulty one and it still didnt solve anything(I did it to both ram sticks.

I just dont know whats wrong and this is really ****ing me off:(

The only thing i can really use my computer for is for the internet but i fear having too many tabs open incase it shuts down:(

Please help
 
Hi Zip

Umm, might be worth checking your CPU temp? Random shut downs like your describing are normally due to the CPU overheating...

Fisrtly, Have you actually changed anything recently that ties in with the problem? Driver updates etc.

You done the right thing by swapping the RAM sticks around. Try both sticks one at a time and then again in different banks. If the it works in one bank and not the other, then it could be a problem with the memory controller.

Whilst talking about memory, make sure the RAM is recieving the correct voltage (vdimm) Check the manufacturers website for recommended settings and run memtest for a few hours.

The next step is to review your system temperatures. Grab CoreTemp as check that everything is okay with your CPU and system.

Finally, make sure that all power connections are in place and that the 20/24 pin is secure and in place. Check the pins are making good contact and aren't blocked inside. Same for the 4/8pin connector.

Ive taken out all the power leads and conectors, even the hard drive ones, i cleaned them and put them back in so it cant be those.

My PC has never had any temerature guage on it and i dont know how to check where i could find a temperatures. :o

My PC isnt overclocked and never has been and i havnt played which any of the settings like that

One thing that has me concerned is Ebay.
When i go on that the page just keeping going down.(i think if they use a moving image because ones with a still image dont do it)


Not how far the crappy wheels have gone down on the page. They just keep on going and never stop:confused:

Well if you feel it is a virus then boot into safe mode and scan from there or better yet make one of those fancy bootable disks with a virus scanner on it. I've never done the latter so maybe someone else could explain that one for you.

Bart PE. A few links below:

The one recommended in one of those articles is a bootable AntiVirus by Avira, it is brilliant.

Just a quick note regarding this, make sure you download the latest plugins, and enable networking and update the AV Scanner before you scan (this is done when you boot from the CD/USB drive).

Also, you will need an XP Disk to create this, I had to use an orignal XP CD, "XP" CDs from an OEM Manufacturer such as Dell will not work(or I cannot get them to work) but OEM XP versions from OcUK will work.

Hope this helps.

Indeed if you feel it is a virus, try running Adaware or Spybot (both downloadable free from internet) from safemode and see what it finds.

It does seem like it may be your CPU temp though, install a program like 'Everest Ultimate Edition', this will show you your CPU temperature in Windows so you can see if it is getting too hot.

If you suspect one stick of RAM to be faulty, run a program called 'MemTest' on each stick, you can download this from internet, burn to cd and run at boot up.

Cheers,

Alex
 
Problemwith the disk is cant burn anything at all.

And ive tryed to scan in safemod and that shuts down too.
 
You need to test the temps and check the memory as I've instructed above.

Can't help you unless you follow what's been suggested as this helps eliminate possibilities.


The explorer problem could be Opera.. Do you get the same problem with IE7 or Firefox?

Yup i second that, you need to check your temperatures it really does sound as if it is getting too hot. You may be able to do this within your BIOS, most now have temperature monitoring built in.

Also another possibility is that the PSU may be faulty.
 
Ive checked the ram(besides doing memtest) so i dont think its that.

Ill have to find out how i can check the temperature on my computer.
Ill be back with results later

Internet Explorer also causes problems.

Anything that puts any stress on the system at all really
 
Ok CPU temp is around 73-75 Degrees.

The CPU shut of temperature is 85 degrees.

So thats probably whats causing it.

If i push down on the CPU fan/cooler i can drop the Temerature down to about 68 Degrees after about a minute so would it be worth trying to screw down the CPU heatsink tighter with some plastic screws to get it to put more pressure between the CPU and heat sink?
I still dont know why Ebay seems to go half way down the screen though
 
Its just the Stock standard one that come with the Computer(Its Celleron D :o)

I havnt changed anything at all, i havnt even really installed any games or programs in the past month or so.
 
Zip, ebay does that for me too. its a problem with Opera, not a virus.

73C for a CPU is insane. your PC probably has major issues.
 
Earlier you said that you'd cleaned the CPU - have you been putting some thermal paste between your CPU and your cooler after having taken the heatsink off the CPU?
