I don't see anything glaringly wrong. The video card is a little old, but that wouldn't cause the computer to slow outside of games or other graphics intense programs.

Of course, that's assuming everything is working correctly. Have you run any benchmarking or diagnostics?

If not, I would suggest running Prime95 and Real Temp for at least an hour and looking at the hgihest temperature the CPU reaches. While I don't expect heat to be an issue, it's something that can be checked quickly.

After that, download MemTest86+ from memtest.org, burn the ISO image to a CD and then boot from it (like you did to install Windows). Let that run overnight or through at least 7 passes. That will let you know if the memory is good.

The main culprit of freezing/slowness would be the RAM, so start with that.

btw, about the prime95. how shoul i run that??

You download it (find the links in the Step-by-Step Guide to Building a PC) and install it. Then just run the program. Have Real Temp open at the same it.

Is that degrees F or C? If it's F, that's extremely cool. If it's C, it's extremely hot, which could be the problem...

That's because Prime95 is used to stress the CPU. The more the CPU works, the hotter it gets. The 45 is the base temp.

Are you using stock cooling? What's the case?

How many case fans do you have running? Are you sure you install the CPU cooler correction (used thermal compound, screwed down tight, etc.)?

You really need case fans. I'm willing to bet that will solve the problem. Or at least keep your CPU from bursting into flames.

However many you can fit. Look for some quiet ones, as I believe you can search on Newegg by decibals (dba).
