Computer Shuts Down For No Reason

Hey guys, good to be back :/. Im having a strange problem. While im doing things on my computer, playing games, typing, surfing the web, (ANYTING). My screen goes black, and it says "PC NOW ENTERING POWER SAVING MODE", then it just restarts. I log back in, and after bout the same amount of time, it does the exact same thing again. ANy help?

Thanks

Any day now.....

Ok it still does it, but i think it only does it when i play games?

Swap in a known good power supply and see if that stops the reboots......

Ill try that, but i never had problems with it until a few days ago.

Any way to reproduce the problem on demand? Is it a specific amount of time each time it does it or does it vary?

Does it after about 20minutes. Well i think so, lets say the game im playing is exteel. Im doing a capture the flag, and i can do the whole game (10mins). then i start another game. and it shuts down with like 2mins left (Outta 10mins). but sometimes i can do 2 complete CTF (10min each). and it wont shutdown/restart until i start the 3rd 1.
sooo yeah....

Weird. I'd suggest an overheating problem with the graphics card (I had a similar issue just last week) except you say it's entering power save mode? Do you mean the computer goes into sleep mode, or is it just the monitor going into power save mode? If the whole computer is cutting off and rebooting, it's more than likely a power supply or overheating problem.

Whole computer does it, but i know its not overheating, the graphics card has a fan on it > and its very weak...
and ive had it in a different computer, playing same games, and it never reset.

Most likely overheating (CPU or Graphics)... maybe power supply, Download a Temp. monitor program (HWmonitor)

Link here: http://www.cpuid.com/download/HWMonitor_113.zip

If CPU temp registers > 70c than system will shutdown; typical settings (38- 55 @ idle) running games and multi apps boosts this temp. Graphic GPU's run around (50 - 90c).

Clean CPU fan with brush and compressed air with system unplugged... this will bring down the temp.

If temp is in range than PS is likely to be the culprit.

You are I guess aware that Spybot is not an antivirus program

Can you please tell us what your installed antivirus program is ?

You have Zone Alarm Firewall? Do you also have Spybots Tea -Timer enabled?

Actually i got rid of ZoneAlarm firewall, to speed my computer up. I have an updated version of WIndows Firewall. Pretty good if you ask me. And, i got rid of SpyBot, (I know its not a ANtiVirus). But when i had it i have them completely update, and TeaTimer was on every time.

Ill try the overheat thing. MY CPU is round 97 degressF. I checked in the Bios Settings..


ANy help??

Thanks

Can we know what your antivirus program is ? Also, when , as suggested, did you last clean the dust from within the computer cover?

Another thought, is the computer tower itself in a well-ventilated area? ( and not parked next to a heated radiator!!)

I dont have an antivirus > There is no dust within computer cover. Its on the floor, (Where its been past couple months).

I really dont know what the problem is?

I would love to play games again :/
