Hey every body,I have a really ,really old system I'm trying to keep together with some coat hangers and duct tape till I can save enough for my next build(no job right now it sucks)Any way I have an old Asus P5AD2-E premium board with a pentium 3.4 ghz prescott,sound blaster live,old Geforce 7950gt with 2 gbs of corsair xms2 5402v5.2vt ram on 1 gb single sticks.I was getting all kinds of thermal issues,slow downs and occasional B.S.D.s My hard drive is a seagate 500 gb brand new and it's working fine.swapped my antec 600 watt power supply for a tester I keep nearby and it's not that (i since put the antec back)could be the CPU but that seems a bit odd.The only thing I was left with was mmemory.I don't have memtest but my bios showed one stick reading funny.I didn't want to spend a ton of money on ram so I bought some cheap corsai value select DDR25300 the model # is VS1GB667D2...problem is not much value.I put the 4 sticks in and my sys posts and then freezes and I'm stuck watching a giant Asus logo..tried rebootin and got a no hard drive detected...I put the old ram back everything works ..ok...the new ram has really slow cas lat...5-5-5-15...could it be i need to adjust that in my bios before booting or am I dealing with something more...sorry for such a long post...can't believe all 4 sticks could be bad...maybe asus doesnt like my ram?...help my machine is slowly dying a slow and terrible death help me save it awhile longer.Thanks...raykat
