Pc not booting

[razor1979]

i built a new pc about 8 months ago and has been working fine then 2 weeks ago i noticed that core 1 of my processor was maxing out and i decided that it was a good time to rebult the OS

after formating and installing a fresh copy of vista ultimate sp1 it was working great until yesterday

when ever you reboot the pc or turn it on it seems to get stuck at the checking memory post check or checking the ide drives

the keyboard is still active as you can turn the num lock/caps lock on and off but you cant del into the bios

after about 15 resets it finally booted up and was working great until i switched off and i got the same problem,

any help would be great

Have you checked your ram ?. Like take them all out but one and test them one by one, all so try different memory slots too. Could try resiting your video card too. You have your case speaker connected so you can hear beep codes if any ?.

Going by your specs it dob't look like you you use raid, reason i say is i turned on caching though device manager and it screwed one of my drives until i pluged in the sata drive just after were it locks up on post. Booted in XP and problem was there EVERYY time i rebooted. Funny though as when i pluged the sata drive in just after it locks up and went into vista it worked fine ever since.


Maybe it does it will some single drives too ?.. Could not tell ya but it's for sure Vista to blame for my raid going wrong and going back right LOL..

EDIT: Forgot to say that were mine did it was just after the memory check. I'm not sure if i can recommend unpluging the sata drive and pluging it in after were the error happens but i will say is it worked for me..., Why i cannot reconmend is becouse i do not know if you need any thing for hot plug. And i left the power plug in it and just plug the SATA drive data cable.

Try other things before this but it sounds really like the same problem but at the same time it could be others like ram.

Try dropping down to 2 or 3 gigs of ram (dont realy need four anyways). CHeck Vdimm settings in BIOS. Load AMD Dual Core Optimizer.
