Fellow antionlyners,

I need help. I've a AMD Tbird 800MHz with 256Mb Ram PC133, Lately, all kinds of things have been happening:

1 - The power suply fan humms until it heats up, then the noise is gone.

2 - All kinds off fatal exceptions and errors happend, on any program, in any circumstancies, such as:

IE 5.5 crashes, Word2000 crashes, games crash, instalation programs crash.

The PC shuts down by himself suddenly and with no warning, and simply reboots.

Windows2000 sais he lost a couple of files such as configuration files and now its all messed up.

I wonder if anyone could help me on what to do.
