Guild Wars 2 Shuts down my PC

[jvzqz13]

I've been reading a lot forums and sadly a lot of people have this issue.... but with laptops. So I don't really know the cause of this. I think it's an overheating problem from my CPU but I'm not sure if it could be from my motherboard like I've read.
I have a desktop, but I didn't build it. It's a stock HP.

Operating System:Windows 7 Home Premium 64 bit
RAM (Memory) : 4GB
CPU: AMD Athlon (tm) II X2 250 Processor 3GHz
GPU: EVGA GeForce GTS 250 512Mb

Besides the GPU, everything else is stock. I just cleaned my desktop from dust, well not thoroughly, but enough to be clean. About 2 hours ago I changed the thermal compound on the CPU and I used Artic Silver 5, to see if it would work. It kinda worked, it expanded my play time from 2 minutes to 5minutes I don't know what could be the problem:/ GPU stays around 50-65c and before I changed the thermal compound, my CPU went up to 40c before it completely shut down on me. :/ I tried to do as much research as I could before actually making an account and asking myself but I can't find anything that has worked.. Can anyone help??? :/

Perhaps your PSU is running faulty. Does it shut down or reboot?

[jvzqz13]

It completely shuts down on me, like someone just unplugged it from the outlet

[Toffie]

Do you know the model of your powersupply?

[jvzqz13]

Yeah it's
Bestec
Model: ATX-250-12Z
REV: D7R

[Toffie]

You need to replace the PSU, your powersupply have gotten worse by time and 250 is very low for the GTS 250.
Perhaps you got some money to spare then I can look for a cheap powersupply for you ?

Or if the warranty of the desktop is still running, then i suggest calling HP.

If you help me look for one that'll be awesome, man. I don't have a warranty on it this desktop.
I'm still a newby with computers, I got the basics down, PSU is where I get confused with most of the time lol

Is that within your budget mate?

[jvzqz13]

Yeah man, that's great! Really appreciate it!

Also, I have a few questions if you don't mind lol

[Toffie]

Great! Sure go ahead

Sweet
Ok so, I downloaded CPUID Hardware Monitor to keep track of my CPU temps and I noticed that Pegatron Corporation 2A99 is on there, I think that's my motherboard, but they both jump to around 40C when playing GW2. Is that healthy? or do I need to reduce the temps on them?

[Toffie]

That looks pretty normal, although could be lower if it werent for those awful HP cases.

[jvzqz13]

Sweet, thanks! cant thank you enough
but haha yeahhh, I only bought this PC for school, never really intended to use it for gaming... till I saw GW2.. lol
Hopefully I can afford to build my own PC soon.
but thanks again.
