Hey guys, first time on this forum. Trying to find some advice to fix my new PC. Just bought and assembled new PC (specs in signature). My system will frequently 'lock' up or 'freeze'. I've noted that the HDD light on the front of the case is on constantly when this occurs. I've gone into the Performance Monitor and the 'Avg Disk Que Length' spikes to 100% when the 'locking' up happens. I've switched video cards and HDD's with the same exact result. I am using XP Pro SP2. I'm kind of at a loss of what to do. I've set msconfig to only start necessary items so I don't believe it is a process slowing me down. After putting in the new HDD and new vid card it worked fine for hours. Ran SuperPi with no problems. Temps are no higher than 52C at peak load. I have not changed anything in the bios other than the boot order(HDD first). If anyone has any insight it will greatly be appreciated!!
