I hope it's ok to post this here but I'm in desperate need of some advice.
My laptop's gone completely nuts.
Basically, the trouble seemingly started when I downloaded a piece of software and installed it. I have now uninstalled it but the problems are still there. Programs won't run. They either don't open or freeze. My antivirus program too. Only a few small programs, like MSN work. When the computer is switched on it just keeps making this noise like it's thinking really hard forever. It usually freezes completely after a while and I have switch it off by pressing the power button.
My antivirus program is called Symantec. I ran a full scan in safe mode but did not find anything.
It was suggested to me that I might have spyware so I downloaded Spyware Doctor and ran 2 full scans, one in safe mode and one in normal mode. It found some spyware and deleted it but the problems persist.
I bought my computer second hand and it was custom built so I don't really know that much about it. I've been told it's probably an HP or an Acer. The operative system is Windows XP Professional. I just had it reinstalled a couple of weeks ago.
I would appreciate any suggestions that anyone might have.
