I've been having a problem with my laptop the last few days that I think is strange (or it could be very simple, I don't know).
So my 6 month old laptop just started becoming very unresponsive a couple of days ago: all windows becoming unresponsive, audio and video jumping around, simple applications like the start menu taking minutes to open after clicking. I thought nothing of it, switched off the computer and came back to it the next day. Only now, after I put my password in on startup, I was just getting a blank black screen. I could open task manager with ctrl-alt-del, but I couldn't actually do anything. So I took out the battery and switched it on and off over and over and each time I got a black screen on startup. THEN, when I did get it to work everything becomes unresponsive either immediately or within half an hour. But every now and then I switch it on and everything works fantastically!
It's not an internet thing, I have the problem on and off line. I downloaded the Windows Malicious Software Removal tool and did a scan and came up with no viruses. I did scans with Microsoft Security Essentials and SpyBot and found nothing either. It can't be a case of the memory being full or anything either coz there's hardly anything on it.
So in short, every time I switch on my laptop I get either a black screen or a frustratingly unresponsive system. But every so often it works great. Sorry if this post is in the wrong place. I'm not sure that it's a virus so I didn't want to post in the 'Virus Removal' thread.
I'd really appreciate it if someone could tell me what my problem is at least. Preferably how to fix it also, of course!
