hi. really old topic but my pc keep freezing. i don't know if i can fully explain it, but here's some info: i had a previous problem with my pc going into boot loops, and had it checked by a tech, and it turned out one of the SDRAMs (i had two 512mb SDRAMs installed) got busted, so the tech removed it. currently, my pc has only the one 512mb sdram on it. also, the tech reformatted the pc it after removing the busted SDRAM. a couple weeks after the above, i started experiencing this problem with the pc freezing. i noticed this usually happened if i try to open some folders is not yet fully loaded (e.g. the windows security alert hasnt popped up yet), but it isnt limited to that. recently it froze while i was converting a video using WinAvi. but it isnt limited to those events, since it happens randomly. restarting the pc using the restart button on the cpu doesnt work, since it freezes again when it reaches the windows startup logo. i had to power the pc on and off for it to work. sometimes, i had to do this a number of times before the pc opens, because it freezes during booting up of the motherboard, and as i mentioned, during when it reaches the windows logo. its quite frustrating! here are my system specs: Windows XP Pro SP3 Pentium 4 2.26GHz 512mb DDR SDRAM Asus P4VP-MX motherboard. nVIDIA GeForce FX5500 two 40GB seagate hard drives is my existing SDRAM going, too?? help please! my pc is quite old, probably around 5 years old. it's not the most high-tech equipment around, but i'd like to keep it running until i finish saving up for a new, better one. also, i was wondering if i need to reset the cmos battery, or change it. i think i read somewhere that this may help but i'm not sure, so i'm not touching any of the internals as of yet. thanks!
