I recently purchased parts online in order to build my own pc. I've made a few PCs this way before and have never had any problems like this. When I first received the parts and assembled the computer it would freeze during the OS install (2000 or XP). I ruled out a faulty harddrive (used another one) and memory (had 2 simm's so swapped around but still same problem). I returned the motherboard and processor and the company sent me replacement parts. This time I thought I had it, I was successfully able to install XP without any problems. However the computer now freezes randomly (reading a DVD, transfering files and even when it is sat their idle) when in the OS. Mouse cursor doesn't move, keyboard doesn't respond, ALT+CTRL+DEL does nothing, to restart I have to push the on/off button.
I have gone through the same steps as before. First I checked the SIMMs, I first took 1 SIMM out and ran a test run but it still froze. I then replaced this SIMM with the other one but still same problem. I even tried installing 2000 instead of XP but same problem. Tried 2 different harddrives (IDE + SATA) but same problem. Tried different CD-ROMs but same problem. I dont have any other PCI cards installed, I've ran a BIOS update which went fine but still have the same intermittent problem. Here is the spec for the PC:
ASUS P5P800 MX 775, 865GV Motherboard
Intel 3.2Ghz processor with hyper-threading
512 x 2 RAM
I am suspecting a problem with the motherboard or CPU but I'm not too sure as these are both replacements (although I did get further with these parts than the first bunch they sent me). I am totally out of ideas and not sure what to try next.
I'd be grateful for any tips or advice anyone can give me.
