Hey all.. k heres my problem.. I am doing a few upgrades and buliding few new systems. I took basically everything out of my (working) system and put it into new case with only a case, psu, video card change. Now everytime I try install XP i get the blue screen IRZL_NOT_LESS_OR_EQUAL. I have tried everything. Switched all components with working etc. The only way i can get it to stop crashing is to disable CPU Internal Cache in the bios. Why is this? i dont know much about cache. But Im pretty sure buy disabling this it will affect performance. And it was all working with the internal cache enabled before hand!!! Is it possible (although I was pretty bloody careful) that the CPU got damaged maybe? Wouldn't that kill the processer though? I am completely stumped. Any help would be awesome! Incase you want to know heres what its running... MSI K7T Turbo2 Motherboard Athlon 1.4Ghz (Not XP) 512MB PC-133 Seagate 7,200RPM 40Gb HDD NVIDIA GeForce 2 MX 32MB Liek i said I had all of these components working together in my system before I swapped them! ???
