Restart problems

Lately i have been experiencing some problems with my computer, every time when i open programs (random, not one in particular) that recquire a lot of your computer, he somethimes just restarts.
I went into my control panel, then system, advanced, restartthingies and i unchecked the "Restart computer auto" under systemerrors. Next time i had the problem, i got the blue screen saying that there was a problem and that windows had to be shut down to prevent damage... AT the bottem of the page i got the error:
***STOP: 0x000000 (0xc0000047,0x804F7E2A,0xF78B2BD4,0x00000000)
Mostly i get this when playing games (especially when i was playing WoW Beta, it did happen 3times in 15houirs of guildwars), or when opening lot's of programs.

I searched in some forums and started checking some things. First i checked the temperature of my computer in my bios (when starting it up first time) and got 39° C, dunno if that's much or not . Next thing i did was ran a Memtest (for about 5 houirs, then someone of my family needed the comp..., got 11pass and got no errors)... I suppose that was a good thing, next i was searching along the forums here and found some cpuz program to analyse the comp or whatever... Here it is :

So the question is simple, any ideas, sollutions, comments, feedback or whatever. SHould i run the memtest longer or annything? I am very bad with computers, i hate them and they hate me, so can you say things as simple as possible plz. Thank you and sry for the bad grammar

Hmmm, sounds exactly like what i had when my power unit wasn't good enough, sometime later it exploded or rather, short circuited, so i guess you'll be needing a better one if that is really the problem, i can't tell you anything more, not a pro (yet )

Could be a reasonable explanation, don't like the exploding part tho. SO replacing the power unit with a more adequate one could be the sollution to my problem?

I don't know for sure, but it may work, you should try to be sure this will help, of course, maybe one of those (what to call 'em, let's see) experts, can help you out, i'm not a real pro in this sort of stuff.
And don't worry about the "exploding" it won't happen until you've used it way too much

it doesn't sound like anything to do with your PSU. How old and what brand is your Hard Disk? Windows Blue Screen of Deaths are usually caused by hardware errors, I used to seem them quite often on my dad's laptop before the HDD gave out and died.

It could also be a hardware conflict aswell. When did you start getting these errors and did you install or remove any new hardware beforehand?

Well i bought this computer let's say a few months ago, but at first i did not experience it one time, mostly because most of my tasks didn't recquire a lot of performance (just some typing in word the first few moths), if that has anything to do with it. It was only when i took up gaming again that the problems rly started. I only added my ethernet card for my internet acces, but nothing else regarding hardware components and such. The only thing i installed was my old printer and scanner(from my last comp) + the new mouse and keyboard i bought (Logitech MX 900).

I am leaning towards PSU. If you start to run demanding programs your computer requires more power and if it does not get them it says no and reboots.

look on your PSU and there should be some number
+3v
+5v
+12v

next to these there will be a number can i have those number, most imortnalty teh +12

Forgive me if i'm wrong, but wasn't it supposed to be mainly about watts?
I now have a 250w, it used to be less, and my bro also said when i ordered my new parts(of which my cpu was ripped off )i should get a 300w PSU.

Watts is the amount of power
amps is the current

both are imporant. However sometimes you can have 600W power supply but it can not deliver it fast enough (not enough current)

Sry but i'm a complete fool at these things, is this located inside the comp or on the outside, have seen some sticker saying 230V if that helps ya out...
Oh yes i have something to add, i just started the computer and it happent again, was just clicking the MSN button and bang restart...

Ok ok i finally found it, there was a sticker... luckelnot all chinese oh yea and there was some weird symbol i didn't know what is was, it was something like this: ___ (three little lines under a big one, in the text below i wrote is as (*) ) ---
HIPRO(i think that is the brand)
Model: HP-D2537F3P
AC INPUT (47-63 Hz): 100-127V/6A
200-240V/4A
DC OUTPUT: +5V(*)/25A, +12V(*)/14A
+3.3V(*)/18A, -12V(*)/0,8A
+5VSB(*)/2A
+5V & + 3.3V SHALL NOT EXCEED 165W
+5V & + 12V SHALL NOT EXCEED 218W
MAX OUTPUT POWER: 250W

I say 250 is quite low. If you were to add a graphics card you'd probably fry your PSU with the extra heat from the amperage. (the transformer windings most likely have the thin coating of plastic, and if you blast the amperage too high, that stuff melts fast). A better PSU might help.

You need to get a better psu to run that system and nowadays they are cheap. Make sure u get something around 400w. But I would try updating your video card drivers first. I had a similar problem and I updated my drivers and so far so good.

If you had a 600W PSU, with little current, I'd be afraid to put it in the computer. That's way too many volts for a circuit board to handle.

drivers wont cause restart not if you get a blue screen than error and have to reset thatn i doubt it

i think you need to get a better PSU which should solve the problem but what video car do you have.....i need to find you a link about a PSU guide i will get it up later on tonight

I have nVidia Geforce FX 5200 128Mb, ow yea and regarding the new PSU, should there be any details that i should take in regard. WHat are the best brands of PSU, can the wrong choice of PSU cause conflicts with your motherboard or something like that?

http://www.hardforum.com/showthread.php?t=792566


here is the guide

if you want what i would do is download mother board monitor 5 and see what happens to your volts if deviates from +or-.5 than i would replace the psu

either way if is not the problem i would still upgrade just because PSU are imporantant and often overlooked

edit=
in repsonse to your question yes there is- if you look on your mobo manual it shoudl say if you need a 20 or 24 pin PSU connector

Very weird what happenend now, i decided to install the latest drivers of the vid card... It asked to restart, i clicked yes, the computer restarts... But everytime i get the blue screen and it restarts again, never reaching my starter page.... I got it fixed tho by restoring the system. Anyone can explain this?

if you are running an asus motherboard, and running 2 sticks of ram make sure they are in slots 1 & 3 and not 1 & 2, this is a common mistake made by people running asus boards when building their system. Having them in slots 1 & 2 will cause yoru system to crash and reboot.

Yes i checked the Bios they are in 1&3, hmm going further on the temperature thing, are there any programs that measure the computer's temperature? And how do i check the max temperature that my comp will allow before restarting?

i have this very same problem and i have just updated my drivers to see if it will work. somehow i think its to do with the operating system becuase it says check for any windows updates you might need.

now my problem is solved. i downloaded a nvidia update for my geforce2 gts gfx card and now it is a geforce2 pro. it doesn't close down at the loading screens but my internet connection closes down every 1 and a half hours so i have to keep reconnecting it but that isn't too much of a problem.

Sry to bother you guys again, but i would like to know where to find the max temp allowed by your computer, i tried searching in the BIOS but didnt find it, i have XP home btw.
