Specs: Windows Vista
Ive been having this problem for a while now. I have recently built a new PC from scratch and am having major problems with crashes which are becoming unnaceptable now I'm coming to do some important work on my PC.

It all began when I installed OSX on my PC, it has since been uninstalled but has left a very bitter taste. I consider myself an advanced PC user but this problem has me almost totally stumped, im infact not sure if its even solvable swapping out each individual part of my machine until it stops.

Anyway, the first time this happened I was watching TV on Media Center, the PC just froze, no message, no nothing just completely locked up. Upon restart the PC first off reported S.M.A.R.T. status bad on IDE channel 2. I dont have a IDE channel 2, I have a Sata hard disk and an IDE CD drive, so this is the first confusing bit. On pressing f1 to continue the computer stats it is missing NTDLR and i must reset. Upon the second reset I get a Boot disk failue.

The incredibly odd thing is that if the PC is turned off for a few seconds (hard drive losing its capacitor power?) it will then boot, but it will not lose is S.M.A.R.T. staus bad.

I have installed a fesh copy of vista but the problem resides. It presents itself often in Media Center, watching it for more than 30mins usually kicks in the crash, but it is totally intermittent. It can also be caused by full screen flash video and most recently a full screen mp4 in quicktime.

My first assumption is that it is a hard-disk problem, due to the smart status of the disk, but this makes little sence to me as the problem is so intermittent and occurs when i am not using my HDD (plying video off external HDD, flash online content (although this may dump its temp files on the HDD))

What are peoples thoughts, can a hard disk cause these kinds of crashes? Can I do a more accurate diag on the HDD to find out WHY the smart status is bad???

I'm usually the type of person to figure these things out myself but my Director is not best pleased with the news of my PC crashes... Any help is greatly appriciated, thanks.

Three things come to mind...bad RAM, crappy power supply, overheating.

Just finished a 3 odd hour check on the HDD, samsung HDD utility is also reporting an error on a full read of the surface and suggests i use the utility to wipe the HDD, onto which i have just re-installed windows.

Every time I install windows I seem to end up doing it 3 times!!!

I'm pretty sure I can rule out overheating, the CPU is never at full load and has a high end heatsink attached to it, and somehow I just can't imagine it being a graphic card overheat.

Ram and PSU are both possibilities, I think im guna have go through the elimination process :(
