My computer keeps crashing. At least once or twice every hour, at least. It just stops suddenly at random intervals. The computer stays frozen like this for up to 20 minutes. After whenever it starts again, it just does everything I did to it whilst it had been frozen (for example, if using Word, if when it crashed I typed in "Blah blah blah" then after it uncrashed that would appear on the screen).
The initial thread I started was this: http://www.geekstogo...ng-t184693.html
As you can see from looking through that thread, myself and Essexboy have done just about every scan under the sun, and I'm 99.99999% sure there's no malware causing this. We're both quite sure it's a hardware problem.
Now I'm not really very good with all this hardware stuff, so I'm gonna need clear instructions here. I've already taken apart the PC case and used some compressed air to clean out the main grills in order to try and stop a suspected overheating problem. However, my computer still freezes. I also tried running the computer with the sides off in order to let maximum air in and out. but it still fails. So I doubt it's overheating then, unless there's dust where I can't see.
When it crashes, the blinking red light on the PC tower stops blinking. i'm not sure if this is a CPU light or a Hard Disk light, but it's got a little icon above it which looks like a cylinder.
Whilst typing out this topic, in fact my computer has crashed twice.
I'm getting really desperate. I really need this fixed because I have to use my computer for exam coursework! And the deadline is approaching fast. It's almost no use if I can't really do it at all without crashing so often.
Inside the case it appears there are three fans. A bright blue one, attached to the motherboard, which is spinning just fine. A second, smaller black one attached to the back of the case, which is also spinning correctly. And a third fan, which is inside a big box attached to the top of the tower. I can't really see whether or not this fan is spinning because there's a box in the way :-) The box has "Switching Power Supply" printed on it.
If you have any ideas on how to fix it they would be much appreciated. I am happy to do any scans/maintenance, etc. Essexboy at the malware forum thinks I need a program that can monitor my cpu temperature, voltage, etc. in order to see which components might not be functioning properly. But you're the experts, so I'll trust in you then if you can help me.
