My newly built PC is freezing shortly after I boot up Windows. It seems to have been taking less and less time to freeze over the past couple days. The screen freezes at its last active point (no black or blue screen). After researching a solution, I was wondering if my power supply does not meet my motherboards needs. I am running the Intel 955x board with a Coolmax COOLMAX CX-550B 550W. The intel site says the board requires an ATX12v supply. The power supply says it is ATX v2.01. Is this causing an incompatibility? Here is the newegg site for the power supply http://www.newegg.com/Product/Product.asp?...N82E16817159026.

Any help appreciated.

I have also messed with the hertz rating on the monitor. Is this a possible cause for the freezing? I have increased it from 60 to 75.

ATX12V is the generic power supply type and ATX v2.01 is the specification revision version number.

For example, see the following:

The newer CX550 appear to be Intel ATX12V/ATX 2.03. See:

Here's a useful site about power supplies:

Basically, make sure your PSU can supply enough amps at operating temperature.
