Some specifications about my system: Motherboard: Asus A7A266-E CPU: AMD Athlon XP 1700+ RAM: DIMM DDR 256MB Graphics Card: Nvidia Geforce2 MX 400 (64Mb) Network: Realtek RLT8139 PCI Fast Ethernet Sound Card: Genius SM-Live 5.1 Disk: IBM 40 Gb The freezing happens with all kind of operations, during XP install (after a format), during booting, in windows xp, watching a movie, etc... And this is not heat related, it can happen right in the morning (after 5m of working in some word document), as well as night. I've sent the whole computer to repair, they've (said that) changed Motherboard and CPU and, but it's the same. The DIMM's were changed earlier, for a new ones, and it stills continues. I've tried: - Formating the disc - Installing XP (I had 98se) - Updating BIOS - Updating Drivers - WOrking with no extra hardware (turned off sound card, network card, cd rom drives) - Changing RAM Is there any way that I can know what's causing this so I can fix it? I have no ideas left...and this is driving me crazy. If I send it to repair again I'll be a month without computer and they probably send me the this the same way! I've tried a search, and tried some of the stuff you said but again no changes...

I had it happen about two years ago and it can be frustrating. Mine was a screwed up file in IE5.5 I never got a message that said it was corrupted or missing, and someone on this great site just happened to figure it out. So I assume you also checked on drivers for mouse and keyboard? No problems with sound card or Windows sounds?

What wattage power supply are you using?

Bruno, I had the same type problem. It ended up being the power supply. I built the computer in June this year. worked fine for three months. Then started freezing. ever so often, then only after a few minutes. I replaced all the hardware, Intel replaced the motherboard and cpu (no charge) It still froze. I even tried booting with only the video card and the power supply connected to the motherboard.(recommended by Intel)It still froze. The only thing left was the power supply so I tried a new power supply and it solved the problem. The case was a SkyHawk and so far I haven't been able to get them to even answer me much less replace the bad power supply. So I purchased an Inwin 300watt. Alls fine and working great. Good Luck

JonhT is not a driver problem...hell it even crashed on Xp installation and disk format! Apart from this I updated all the drivers anyway. ben rogers, chopk: thanks I guess it's the only thing that I haven't tried out. What I've got to loose? I'm going to buy a new one. Thanks for the advice.

When your computer frezes does the clock stop?I am having the same problem with mine.It freezes up whebever it wants to.Sometimes on the web or just with the screen saver.

I just bought a new power supply (350w) and it didn't solve the problem...I thought it had solved but no. it run fine for 2 or 3 days but then the freezing came back. Daryl: the clock stop? erm..I guess so..it freezes the whole computer, nothing moves. If it freezes when an mp3 is playing then the sound loops over and over.
