I recently purchased a rig from Dell, and I did that planning to insert my old GPU into it and save some bucks. This has and is working pretty well atm, although I had to also put my old PSU into it cus the one I got with the computer lacked the GPU-powerslot.
Anyway, most of the time the rig is working perfectly fine. But at about 3 occassions there's been the annoying event that my computer just shuts down. No kind of bluescreen or error msgs, it just dies. Every time has been during a point when I was playing a game. Starting it up works perfectly again afterwards (thank god).
I have 2 things I personally am suspecting could be the problem.
1: My PSU is at ocassions incapable of supplying enough power, most likely due to my GPU which is an ATI Radeon HD 4850 and a powerhungry beast and its cooling fan spins up like nuts when I play a game.
2: The rig gets too hot, like I said I have the ATI Radeon HD4850 and it's currently using the stock cooling, which is poor indeed and it does indeed run pretty hot when gaming.
So basically I was wondering about your opinions, does either of these 2 suggestions sound like they could be the cause of the computer just dying all of a sudden? Which of these 2 would most likely be the reason for my problems?

the chances that one or both of those are the source of your problem are pretty good, the chances of it being something else are pretty good too.
please give us some more information about what you working with.
also helpful to know if you noticed anything just before or around the time it happens.
any smell, unusual noise, sound, blinking, etc
try to repeat what you did when that happens and see if it happens again
are you sure that the psu is compatible with your system?
dell often uses proprietory parts and regular atx standard psu's won't fit as well as power connectors can be different.
did you install any new drivers, software or updates recently?
did you install any other hardware or peripheral devices recently?
hopefully you did this before installing your psu and gpu.... in that you de-install the drivers of the original onboard or add-in Dell's graphics. Also, if it was an onboard gpu, disable it within bios (if it lets you)...
Now you say that so far it only happens while you are gaming.... yes this could be heat related... one thing to try is to take of the side panel.... and maybe have a table top fan blowing over the components, but for sure take off the panel... see if this helps. If the system stays up and you have no issue while gaming. then over heating is your issue. In this case, you need to look at your case setup and figure out what and how to modify your case to get more air into, through, and out of that case. Larger the fans if possible. Larger fans can move alot of air at lower rpm and be quieter than small fans that has to spin much higher to get the same cfm but at the cost of being noisier.
Only thing I've really noticed is that the fan of my GPU starts running faster, which is to be expected while it's set to auto-speed and I turn on a game. Other than that, the rig just shuts down completely.
Not sure how you mean that my PSU would be incompatible, everything from harddrives to motherboard and GPU uses standard connectors, I've never seen any other type but they fit perfectly.
Not really installed anything new recently either, and tbh this issue happened the first time like a month ago. Then nothing, and yesterday I tried a new more graphics-heavy game and it happened instantly.
Good idea about the on-board gpu drivers, don't think I ever bothered to install them though but I'm gonna look it up, and if possible even shut it down via the BIOS as it is, indeed, an onboard gpu.
Yes, I was thinking of trying that with the sidepanel, I did it before on my old computer and ended up with a ton of dust in the rig cus I kept it off, but I could do it just shortly to try it out.
However, is there any of these 2 suggestions I've given that you feel is the more likely issue to cause a complete shutdown like this? Is it more likely to be overheating than low-wattage? I believe I have a 420W psu, and it's a pretty good brand if I'm not mistaking, but the fact is my GPU is suggested to require a minimum of a 450W psu, which is why I was inclined to think this was the problem. But you guys sound as if it may quite possibly be overheating causing this issue, atleast as likely as if the PSU is too weak?
If indeed this issue of total-shutdown is "known" to be a possible problem caused by overheating, then I feel sure this is the issue. Simply because of the really poor cooling on my GPU and the amount of heat it generates.
Unfortunately I have no such options atm, and I feel inclined to believe it's a heat-problem too, although ofcourse I could be wrong.
The issue occured today again, when I was testing a new game. The thing is when I push my GPU, its heat rises to some sick 110degrees celsius. And this was with the side of my computer-box open. And it seems to be it's whenever I push the gpu that the system crashes, so I am thinking the GPU is just getting overheated and therefor causes the problem.
I guess I gotta go buy some secondary cooling and replace the stock-cooling, something I've never done before btw. Also, the cooling I'm probably gonna buy is gonna be the arctic cooling twin turbo (not pro), in case you have any opinions about that.
Well, don't really see any other option atm, if this problem persists after a (hopefully) successful replacement of the cooling system, I guess it has got to be low power, or could it be the GPU is "fried" somehow so it can't take workloads at full performance anymore?
