My pc is a HP s3700y slimline. 320 Gb hard drive, 4Gb 667Mb RAM, 2.6 Mhz Athlon xp x 2 5000+ cpu. 2 months old, and my pc keeps locking up. Have windows vista 32bit home premium. I have done everything HP tech has told me and i STILL have this issue. I never had this problem with Windows xp professional on my other pc. Go figure!
