I just had a P4 that had those exact problems, out of the blue would shut down and sometimes had to completely power off and wait before it would restart. it was a buildup of dust in the fins of the processor heat sink.Then another P4, exactly the same model and config, wouldn't shut down, but froze and the mouse jerked around erratically. Was the same dust problem. I'd try that one first, as it's the cheapest to fix.

yeh did that a couple of days ago and it fixed it btw can i close this thread or not? lol im kind of new

you know when u went on the website and it said open and stuff did u actually open it? or just go on the website to get the virus

yesterday i opened my computer and cleaned it saying as it's been there for a year untouched and after i plugged it all back in it worked fine it was on all last night andall today without switching itself off so i think i fixed it

I experienced this before, my PC randomly restarts because I installed a software then immediately used it without restarting.If you installed a new software, try to uninstall it first, reboot, then install your software and restart again. That's what I did and my PC is fine now. Try also to clean your power supply, CPU fan, etc. Make sure also to connect the power supply plug directly to the wall socket and don't plug it to extension wires.

by power supply plug do you mean the one that goes into my computer to power it if you mean that then mines plugged into an extension cable cause i only have one wall socket

This may be caused by your computer overheating. Has your computer been making much noise lately? You may need to replace a fan in your tower.Try opening up the tower and then starting up the computer to see if the fans are running properly. If a fan is either no working or if there is one making
unusual noises then I would get a new fan. While the tower is open, I would suggest cleaning the inside by blowing all of the dust our with canned air.
Sometimes collected dust can slow down the ventilation in some areas.

ill open it up today and clean it out its been there for at least a year or something it's probley covered in dust

sometimes my computer switches itself off at any moment without warning it just instantly turns off i don't know if its when i run some programs or not cause if i try to save something on windows movie maker it turns itself off and the turn on button won't work until i switch it off from the back and then back on anyone know whats wrong?
