1st my spec
intel E4500 2.2 GHz
intel 946 gzis mobo
1 GB transcend 667 ddr2 (single channel)
160 GB samsung sata
1 asus dvd rw
mercury KM84 casing with it's psu(395 W written)
and that's all, no external graphics card
normally there is no problem with this while i'm browsing, office work etc.

But while i'm gaming (please do not laugh) like-age of empire-2, Warcraft-3,robin hood, fifa2007 or fifa 2008 etc with low-mediam setings @1024*768 ther is also no problem, the games run smooth(at least smooth to me),but after 10-15 minutes (some times 4-5 minutes,and some times 1-2 hours) the pc get restart. And there is a sound like (pichek or breek) while restarting. And some times i play all night there is no restarting.
I reistall the XP, upgrade the bios, upgrade the driver(graphics, mobo) but still the problem is not solved. i googled about it but find no answer.
I know my spec and problem is very laughable to you, but still can you guys give me any suggestion where my problem is?

Sounds like the PSU is iffy. Go to the PSU sticky and get a tier 2 or 3 replacement PSU.

You need a graphics card to run games well.
I think that is your problem.
How many amps do you have on the 12v rails? You could be overtaxing that power supply. Look at the label.

Sounds like a heat issue to me; have you had a look inside your case to see if the vents and grills are clogged in dust?

Hi, thanks for the replying.
for heat problem- I've checked the heat issue, never crosses above 40'c, i never overclock my cpu.
And i know for game i need graphics card, but this game i mentioned run properly, even sometimes i can play 4-5 hours nonstop, and somtimes 2-3 minutes!

My psu is mercury, model AP-2400
On 12v rail it has 14 amps (wrriten in the psu)

Lets see.. you could:

1.) Set XP to stop on the blue screen to see what details or error numbers that it comes up with. Which is done by bring up system properties, then advance tab, then click on settings for startup and recovery, uncheck automatically restart.

2.) Check the event viewer, I'd look at the system events for hardware problems, or application for any software problems. You can also click on the hyperlink for additional info from MS to see if it can help you out, when your viewing the event.

3.) Double check on the memory spec's. Sometimes the bios will automatically set things up on the memory timings and voltage. If the timings are too tight, or not enough voltages, those things could cause instabilities.

how long have you had this problem?
No, your specs seem ok to me, its not laughable.
In my personal experience I have found several reasons for "restarts at games":
-Memory is incompatible or its mixed or is misconfig.
-BAD PSU or low PSU.
-SATA Hard Drive cable is somewhat loose or its just broken.
-Loose PCI cards (sound, etc).
-Overheating (fan failure, fan is slow or the "remove before install" sticker was not removed from the heatsink. etc)

i've this problem since i bought it.

You know it is a intel mobo, if i change anything about ram(fsb,timing) in bios the PC do not start untill i reset it back to default with the jumper.

I can watch movie, or run highend sowftware like Autocad 2008 or ETABS 9 with out any problem.

it really sounds as chipset overheats after a while of 3D use, or the Pc itself needs more power when doing 3D and that causes a crash due to Power supply instability.

I would do a 3Dmark 2003 or 2005 looping and checking temps. If you don't have a temp monitoring use your hand over the chipset heatsink, normally it could be hot, but it shouldn't be superhot.

Another thing you could try is to borrow a 3D video card, lets say an Nvidia 6200, and try that out.

good luck, Hope you get back with good news, if not then we will try to think in something else.

You should replace that power supply with one that has 16-18 amps on the 12v rails. Your power supply is barely making it.

OK guys, thanks for replying.
Right now I can't afford a good PSU or Graphics card. But after 1-2 months I can go for the PSU, than Graphics card. Cause graphics card need good PSU.
In my country Thermaltake(500W) are available as a brand PSU. Is that good?

Thermaltake less than 600 Watt is not a good brand (Tier 3 or 4), but better than what you have now.
Make sure you look at the 12v rails when buying. That is the most essential rail. Some 400 W power supplies have 14 amps on the 12v rail, some have 18 amps.

well, depending on pricing, the thermaltake could make a better job than your actual PSU. Still, I have antecs and sharkoons and they do a nice job. But if you want to deepen your reasearch theres a PSU stress test available somewhere in toms hardware testing galore.

After doing this, I got the following message in blue screen, And I don't understand anything about it. I don't think it is for bad PSU, or is it?

Interestingly, I had the same type of blue screen problem with my 1st computer, it had Intel 865PERL mobo, but when i changed the mobo to Gigabyte 865 then the problem was solved. Does this blue screen error only happen with Intel mobo?
