hi i've been using my computer for about 2 years now, and it was fine up to a few days ago, when it froze up because i guess i was trying to run too many programs at a time. anyway, i was able to get my task manager up and command my computer to reboot. thinking everything was fine, i left to do some other stuff, but when i returned a few hours later, the computer was still frozen up, it had never restarted like i told it to. from that point on, everytime i turn on the computer, it will randomly freeze up and crash within 30 mins. in addition, if i try a few commands while the computer is frozen, it will then emit a loud 'beep' sound that goes on forever until i force shut the pc down(pressing the power button for 5 seconds). i do not believe this is a fault of a virus or spyware because i have protection programs installed and i've already tried multiple scans/cleans. any help will be much appreciated! its so frustrating not being able to work on a stable environment for even an hour! * to specify freezing, my entire computer just stops (even the task manager monitoring the CPU usage % stops), i am unable to perform any commands, and further tampering as mentioned above results in the death screech. i am NOT experiencing any form of blue screen of death, error messages, or even a notification of system failure upon reboot.
