Hello all. :) So recently I was watching a film on my computer (using my computer) then I get a notification from one drive that power saving mode has been enabled, so being smart (or so I thought) I plugged my charger into my computer. The screen immediately went blank.. So assuming somehow I had turned it off I went to turn it on. Unplugged the charger.. Plugged back in.. Then I noticed the charging LED was not lit up.. Assuming that maybe it's the charger I go to a store to try another charger, they plugged it in and nothing.. Then of course here comes the sales pitch. Since this, the computer has been sitting around.. tl;dr Plugged in my charger and computer won't start. To note: I can't smell any kind of smoke, by battery or inside the actual computer) Charger makes a kinda static noise when ear placed next to the box.. (Plugged in or not)

I have an Acer Aspire 5672 with Windows XP Home Edition. Yesterday I started up my laptop and it did a disk check and found no problems then went to the password screen. Once it got to that screen none of the keys on my laptop worked and neither did my mouse pad so couldn't put the password in. I could only move the cursor with my mouse which plugs into the usb - it is has a fingerprint scanner on the reciever end which was also not working. When I put the cursor over the password box it changed to a hand and I couldn't click in it so still cant put in the password. The mouse also only works if it is plugged in when I turn it on and not if it's plugged in once it gets to the password screen. During startup I pressed F2 and saw under PhoenixBIOS Setup Utility that Password on Boot was Disabled and Set User Password wasnt able to be clicked on. I restarted it over 10 times now and have taken out the battery and put it back in, left it overnight and tried again and still no difference. I also did a system restore to 3 days ago when it was working fine but the same thing is still happening. I did manage to start up in safe mode and once it has started the mouse pad works and I can access everything so cant figure out why it is having problems at the password screen. I am running all anti-virus programs I have (avg/symantec/avast) and am also defragmenting to see if it'll help. I have just changed the settings so I dont have to enter the password to see if it'll let me in but am still waiting for all scans to finish. Also during safe mode when I plugged in my flash drive it didn't show up but dont know if that was just because its in safe mode. Does anyone know what the problem is and how to fix it?

It's my first time building my own PC, and I'mcoming towards the end, but I'm not sure whether it's safe to use just any kettle lead with my computer... :o Here's my get-up: 550w PSU (with the kettle lead connection) 8800 GTS 320MB graphics card 2gb DDR Ram A MSI P35 Platinum motherboard Intel Core 2 Duo processor Is it okay to just plug any kettle lead into the unit? Or do I beed a transformer to go with it??
