OK, people, I'll give you all the details, so you know my situation as accurately as possible. Some days ago I started having problems with my computer -- FireFox didn't load Google nor any other search engine. I uninstalled it several times, tried using SuperAntiSpyware and Ad-Aware to no avail at all (the same for NOD32 and BitDefender for virus)... Finally, I installed XP SP3 and, somehow, FireFox started behaving properly again. Some time after that, my whole computer starting falling on me: it froze out of the blue -- so I had to force a manual restart --, my monitor shut down... It started to get me on my nerves, so I finally decided to format and install everything again. You see, I have a Compaq system with an original copy of XP Home OEM. Yesterday, after everything was finally installed, I was installing drivers and all that... when it froze again. And now, just a couple minutes ago, it froze once again. I'm starting to think that there's something really messed up with my PC, not the OS, but the hardware... so if you could give me hand and tell me what might be wrong, I'll be really greatful. I'm still running XP SP3 Home Edition OEM in the same Compaq PC, BTW. Thanks in advance.
