Hey guys, My computer has suddenly stopped booting for some reason. The specs are in my sig below. Heres the funny thing. .. i havent installed any drivers or programs or anything for that matter in a few weeks. nothing has changed at all, and suddenly no boot. the only thing i can think of is we've had a spell of bad weather in the last day or so with some power flickerings, but no direct lightning. i have it on a UPS, but i suspect it is shot. (it doesnt keep the PC running during an outage like it used to) heres what happens when i power up...
the computer POST's, goes thru the normal tests, but goes to load the OS and all i get is a black screen frozen in time. never seen this happen before. no errors, no special beep codes, no nothing! Im thinking its time to reinstall the OS, but if i can avoid it i will. any idears?

so i did some poking around, and teres an exact same issue on microsoft's site with my symptoms. it all points to the master boot record. i have to repair it (somehow) any ideas on how to do this?

I think you can do that if you use the repair console in Win XP. By dropping the XP CD into the CD ROM. Not 100% sure though.

well, i got it figured out guys. it was my boot sector got corrupt. and for some strange reason, i couldnt repair it. anyone got any ideas on how this happens? i basically had to do a full format/install. 
while im here, i also created an additional partition on my c drive for programs, but in disk management, it just shows the other part of the drive as "unallocated space". i try to right click it and format, but there are no other options other than properties and help. i can post a screenie if ya'll need it. how do i format this section of my C drive? i have 2 hdds right now, c is windows and d is storage. any idea on how to "enable" the other part of the C drive?

NF7-S Bios revision 14 mentions a setting (BIOS > Intergrated Peripherals > EXT-P2P's Discard Time). Not sure what the setting actually does but they recommend that you change it from 30us to 1ms if you suffer from SATA RAID-0 disc corruption.
I guess it's a delay between two conflicting yet vital operations during boot.
N.b. Pretty much got the same spec. machine as yourself (I.e. XP3200+, nf7-s v2, Sonata Case) What your temperatures like? (Mine varies between 35C > 60C).

Ok, to save time for mbr and fat table corruption.
If you boot from the windows NT cd and choose console for repair operations, a you can use the several commands to repair basic functionality. The one you were looking for is fixmbr
http://www.microsoft.com/resources/...ons_fixmbr.mspx
also available is fixboot for the boot sector.
As to the partition, is it a primary or an extended partition. If it is an extended partition then you must create a logical drive within that extended partition. You can then format the logical drive.
For the record book, a hd under IA32 can have up to 3 primary partitions (bootable). In order to have more drives you must employ the nonbootable extended partition. I think under IA64 (the Itanium) one can have more
