I'm also not sure if I should enclude a "back story" of some hardware problems this computer had a few months ago, I don't know if its relevant.
Anyway to the relevant stuff.
Was playing a popular MMO game when the game crashed, which had happened only once before under similar circumstances (too much stuff happening in game, comps specs aren't that good at least thats what I think)but then the computer was kinda unresponsive? afterwards this time and was basically frozen, aside from the cursor. I could move that around but couldn't do anything else really. Even trying to "highlight" the start button wouldn't actually highlight it, at least not all the time and if it did it'd take a few minutes for anything to "register" at all. The computer did seem to be slower recently, even "right clicking" something (to bring up those options) could take anywhere from 30seconds or longer. I wanted to do a "system recovery" (factory settings) just to make sure but the computer no longer had that option/feature since replacing the harddrive and re installing vista ( I have no idea why).
Anyway, restarted the computer and it was still "frozen". Since the harddrive did need replacing 6 months or so ago, I thought it may be the new one messing up as well. So I booted it up in safe mode this time and everything was all good, then re booted it in safe mode with networking, logged into skype to let some friends know what was going on, downloaded malwarebytes and started scanning it. Malwarebytes "froze"/unresponsive for 20 seconds or so after starting the scan and a few times during it (the reason I uninstalled it a couple months ago just didn't seem to work properly on my computer). Anyway, let skype and malwarebytes run then went for a jog. I came back about an hour later thinking the scan would be done but I came back to a skype error code (don't remember it sorry but it was short) and malwarebytes was still running but completely unresponsive. I believe the whole ocmputer was but am not 100% certain on that, so I believe I did a hard reset and tried booting it into safe mode again and it no longer works.
Any mode I try to load up its just a black screen with my cursor on it and I can move it around but its just a complete black screen. Normal mode doesn't even do the freeze thing, its black as well.
Think I can get some help? I'd like to know whats wrong with it and what my options are, I think my only option would be to reformat it and do a clean install, right?
Kind Regards, and sorry for the long post.
