The power supply is definately big enough, however if it is malfunctioning & not putting enough power into the components then it can cause system lockups or BSODs. There could be the theory that it isn't putting enough through the rails but with those components I'd say it more than likely is. Still as said it could be malfunctioning & supplying less power...
How old is the PSU? The comp sounds aging aswell, the capacitors wear down during use as does the efficiency of the PSU, it would be worth trying another PSU just to see how things go.

2-3 yrs not extremely old i can get the one originally designed for this system and give it a try and hope that will work um also what do you mean by rails and capacitors are you talking about on the mobo or are you talking about the powersupply
just wanting things cleared up also the other powersupply is only 480 watts
also if burn marks are on the connectors of the powersupply is that a bad sign as well
True, not as old as it could be, although the spec makes it sound a little more so in my opinion. :)
Well the total wattage of the PSU isn't always the most important part, the 480W (& the 500W) that you have by looks of it can handle the system as a whole, atleast when new, the other part is the amount of amperage the PSU supplies through each of the rails, simply put, if it isn't enough it can cause alot of problems. The Capacitors on both the motherboard wear & the PSU also wears over time which result in less power being supplied, obviously this can cause problems, although usually the only problems occur when there were never sufficient amps in the 1st place. (this likely won't have happened with your comp) however the effects are the same if any other malfunction/defect within the PSU causes less voltage to components.
If there are burn marks about, I would probably deem it unsafe myself, but I don't really know if it really is dangerous, one would assume so. (Logically atleast) As said try another PSU, atleast it'd tell us whether it's the PSU that is the problem or something else.
The other obvious answer for your problem I'd assume you'd have checked internally & externally would be the memory, since memory problems are often the cause of alot of problems. By internally & externally, just to clarify, I mean internally as a memory check with software made to detect defect/bad memory & externally, just to reseat it (take it out, then put it back in)

ok so everyone who hasnt replied has no idea on this issue of mine ........ guess ill trash the system then :( cause aint nothing else to do about it obviously .... guess it was worth the try but there is nothing anyone can do about it :(
you are going to trash the system because no one here has an answer!
i have one ,take it to a computer repair shop!
it hard to figure out computer problems sometime when
we/us /others, don't have the machine in front of us to actually see/hear what the thing is doing . .i will reread you first post and put on my thinking cap and get back to you with my opinion

that is a very bad sign,passably left after a power surge, that also caused damage to you motherboard .
you are using what is considered a cheap mother! and its my experience that cheap is not good ,and they don't hold up well !
examine motherboard carefully with your trained eye,looking for burn marks and swollen capacitors !swollen caps will have opening in the top with the cooling chemical oozing from within!even the slightest amount on 3 to 5 of them will cause this to happen to a motherboard
using a new or known really good PSU,plug it in to only the motherboard ,and the hard drive ,nothing else ,boot to the bios and set it to default setting save and reboot computer and tell me/us what happens .

Just to add, are you 100% sure it is the hardware? While Software can't actually cause hardware defects or similar it can produce lockups & the OS/Comp to lock up instead.
caperjacks suggestion is also a good one to try. I agree you shouldn't trash the system, as sometimes it's difficult to find out the cause of a problem especially when there is no PC in front of you to actually see what is happening as it happens. (This is in reference to us not being able to actually see ourselves what is happening with your comp)
