Hi everyone, i'm new here so please forgive me for any inconsistencies or lack of conduit in my posts. This is what I have: psu: Thermaltake TR2-420W mboard: Gigabyte GA 7NF-RZ (nForce 2) BIOS Rev4 (Most Recent) Northbridge at 47 Celsius in full load cpu: AMD Sempron 2300+ FSB-OC (166 to 200) to 2600+ (1.89) at 53 Celsius in full load ram: 2x256 Infineon PC2700, 1x512 Infineon PC2700 Dual Channel at 166 agp freq: 66 pci freq: 33 ATA hdd: Seagate ST360015A 7200 rpm, hardware ECC SCSI ctrl: AHA-2940UW (Most recent firmware) SCSI hdd: IBM DDRS-39140W video: Galaxy GeForce 6200A 256 MB GPU at 80 Celsius in full load tv card: Terratec TerraTV+ sound: onboard nic: onboard optical: LG GSA-4160B mag: standard floppy, Iomega Zip 100 OS: Win XP SP2 (with 2 software striped partitons) The system above freezes randomly and it's causing me a lot of brain damage. By freeze i mean: the system becomes totally unresponsive, video freezes, sound plays in endless loop from buffer. Somedays it's ok, others it freezes 15 times per day regardless of how I use it. What I have tried: tested the memory (it passed docmem easy) tryed another psu (same result) underclocked the cpu, mem, agp and pci (no change, still freezes) removed scsi ctrl and hdd (still no change) tryed another video card (no result) reflashed the BIOS (no result) updated scsi Firmware (of course, no result) and everything else that I cannot remember I have also tested the scsi hdd with the built in utility in the adaptec ctrl (passed) I do not know of any method to test an ATA hdd properly I have no idea how to test if a cpu or a mboard are ok Please help, and feel free to speculate. I'm ready to try anything in the realm of reason.

"I do not know of any method to test an ATA hdd properly" The website of the HDD will have a test utility that you can download.

Win XP is often set to reboot when it encounters an unrecoverable error. To have XP possibly display an error message instead of rebooting: 1. Click Start, and then right-click My Computer. 2. Click Properties. 3. Click the Advanced tab, and then click Settings under Startup and Recovery. 4. Under System failure, click to clear the Automatically restart check box. 5. Click OK, and then click OK. If you get an error message, look it up on the web using the exact message, or look up the file that is causing the problem. ..... Check your hard drive. See the latter part of response 1 in this: http://www.computing.net/windows95/... If you don't have a floppy drive, you can get a CD image diagnostic utility from most hard drive manufacturer's web sites, but obviously you would need to make a burned CD, preferably a CD-R for best compatibilty, on another computer if nesessary. In your case go to www.seagate.com and get SeaTools for Dos.

Thank you for your support. I've tested all my components again and everything passed except for my hdd wich was not recognized by seatools (everything is properly connected and the bios settings are ok). Is this a sign of my drive failing? Or is this a mboard problem ?

If you have a good IDE cable and you see this, try the drive on another computer. If it isn't seen there, it is a bad drive.

Check the data cable near the connectors - it is easy to accidently rip the cable at the edges when removing a data cable, severing the wires.

Hi, I had the same problem before and I do check every thing and even format my PC as my computer manufacter told me to do but no result, I want you to start you computer on Safe Mode, it it's work properly without freezing that mean you had my same problem, you have a virous in your computer use a good spyware romoval and your problem will solve, BogBog Saif Alnazari
