My hp m9040n computer freezes no matter what, even in safe mode, I tried system recovery(where it re-formats everything to original), I tried doing a checkdisk on C: but I got to 15 percent and the computer froze, I took the side off the computer and blew out all the dust, I don't know what else to do pleaaaaasssseee help. Sorry for bad description but I'm on ps3 typin with a controller

Click start>click run type in msconfig and then press enter. Go to the start up tab and uncheck everything except your anti virus,click OK and reboot.

Run a complete scan with free curing utility Dr.Web CureIt! download free anti-virus! Cure viruses, Best free anti-virus scanner! (http://www.freedrweb.com/)

Have you run scan disk . Does it freeze when you run scan disk ?

Yes it freezes no matter I do I'm going to try msconfig now

I would check to make sure you are not having heat related freezes. You could try taking the side off your computer and position a fan to blow directly in on the processor and the video card.
