hi everyone my first post here ok my prob is after loadin windows and system workin after a few shut downs an power ons the hdd gets corrupted an wont boot windows will either get a blue screen or the system will just keep restartin as soon as the windows logo starts to load. *cannot get into safe mode *cannot use recovery console ( system bluescreens) also the first few blue screens i got was with the NTFS.sys but i now notice the last time i tried it i just got the black screen with a file is corrupted an to repair it. i recreated the error about 10 times or so tryin to trouble shoot an brought it down to 3 possible faulty parts. the mobo (biostar NF4U AM2G), the CPU (athlon 64 4000+ dual core) or ram (TITAN 1gig ddr2 800). however ram did pass memtest ran for about 6hrs reason why i feel is either of these parts is cause i swaped all that i could swap (harddrives, video cards, psus, ) i do not have accesss to replacement AM2 board and cpu nor any ddr2 . so can anyone help me from here as in maybe a software that could test the cpu an mobo... oh an i ran Hot CPU Tester Pro 4.2.3 for 6 hrs an no problems detected. but if i use the system with just restarts an no shutdowns it seems to work good an prob happens when i shutdown and leave for a while ( sometimes i just boot back an get error also) so i am kinda stuck right now in solvin the prob. this is a new system an cant really afford to buy replacement parts . unless i know for sure which one is faultin. thanks if anyone can advise me anything that i can also try. much thanks in advanced also i forgot to mention the mobo battery did came dead and i replaced it. also i am not in the US an cannot just send back each part where i am the stores will check it an if it boots up an thing they will say that the part is good an say they cannot replace it. ALSO i had tried both SATA and PATA harddrives. ALSO Updated the bios to the latest version from biostar site.
