my pc just freezes at random times...i noe its not overheating cuz my CPU is running at 46C...any idea?

Spyware, viruses???? Intel P4 3.00GHZ HT 800MHZ FSB 1.5 GB PC3200 DDR SDRAM 256MB RADEON 9600PRO 80GB 7200RPM SEAGATE BARRACUDA 4 GB QUANTUM FIREBALL 5400rpm

Is it a complete lockup that requires manual power-off and restart or is it an intermittant thing? In ControlPanel> Admin Tools> EventViewer Is there any indication of any software that is associated with the lockups? What kind of graphics card do you have? Maybe that is overheating. Does your VGA card have a fan on it? If so is it working? If not maybe you can get an extra casefan and mount it to blow across the card. Give a man a fish and you feed him for a day. Teach him to fish and you feed him for life.

its a complete lock up, my vid card has a fan on it not shur of its running temp though

If there's nothing in eventviewer to indicate a software problem, then I still lean towards an overheating issue or perhaps a failing powersupply. If you have access to another psu I'd swap it and see if that makes a difference. If it is the psu then it will be important to replace it before a complete burnout as they often put a fatal surge through motherboard/CPU/RAM etc when they blow. The PSU also has a fan in it. It may be failing/blocked up with accumulated dust/crud. I've replaced a psu fan before but do not recommend that unless you know what you're doing as opening a PSU is not the safest thing to do. The fans in them are usually hard wired in so replacing them requires cutting/soldering the wires. Give a man a fish and you feed him for a day. Teach him to fish and you feed him for life.

Did you go into control panel/admin tools/ event viewer and see what errors you are getting when your system freezes up?

in the event viewer im getting errors from my cd drive not booting in the alotted time, but i dont think that would cause it, the PSU that i have came with the case so its bound to be a piece of crap
