My computer keeps turning off and I want to know how to fix it.
I think it could be the weather because when the temperature in my house is cool (below 60) my computer turns off more frequently. (I don't have central heating...)
It turns off when, I'm guessing, when it gets to a certain temperature.
It especially turns off when I'm playing a game.
My anti-virus, Avira AntiVir Personal Edition, keeps saying that I have a virus called "TR.Agent"...scanned in safe mode but still can't get rid of it.
How do I fix this problem?
It also happened before I upgraded.

Specs:
(1)Before upgrade
(2)After upgrade

Motherboard: Asus PN5SLI
RAM: (1)512 MB (2)2.5 GB
Video Card: (1)Nvdia GeForce 4000 MX (2)EVGA E-GeForce 8800 GTS 640 MB
Power Supply: (1)300 watt (2)Antec Basiq 500 watt (1 fan)
Hard Drives: 235 GB, 38 GB, (External USB) 80 GB
OS: Windows XP SP2 Home Edition
CPU: Intel Core2 6300 1.86GHz
Drives: DVD+RW, CD+RW

I would take a close look at the memory and how it's set up in bios? A cooler room should actually help, the only problem is getting booted up when it's cold. That power supply is minimal for that vid card tho?

It would probably be a good idea to start a seperate thread for the virus issue and solve that first.

Hello,

Just to add, when you start up the system, enter the bios and look at the temperatures, keep a close eye on them, it could be that the processor heatsink is not attached properly.

hope this helps
Regards,

Alan.

So which power supply do you have? You listed 2. No matter what the ambient room temperature is you can overheat if your Heatsink is plugged with lint and dust or the CPU fan isn't turning
OK I see you currently have a 500watt. DaChew probably didn't see that either

I think you're right about the antec being overpowered... I will try to get a better one (I was stretching my budget a little). And I think it could also be my metal case it was the least expensive one I could buy.

This is normal?

Field Value:
Sensor Properties
Sensor Type ITE IT8712F
Sensor Access ISA 290h

Temperatures:
Motherboard 62 C (144 F)
CPU 82 C (180 F)
Aux 90 C (194 F)
Maxtor 2F040J0 43 C (109 F)
WDC WD2500KS-00MJB0 41 C (106 F)

Cooling Fans:
CPU 2778 RPM

Voltage Values:
CPU Core 1.34 V
+2.5 V 3.22 V
+5 V 4.92 V
+12 V 11.97 V
+5 V Standby 4.97 V
VBAT Battery 3.02 V

I'll try to clean the lint off of the inside but the case has poor ventilation that might be the problem. It was meant to be temporary but I guess it has overstayed its welcome.
It's warmer in the room and it hasn't turned off. I'll run some "tests"(play FEAR and BIOSHOCK) to verify. Thank you all for your helpful responses.

your cpu should go no higher than 70C under load, and that's too high

I try to keep 10-20C below that

I agree, I believe the PSU is either dying or too low of a wattage to run the system.

Should I get a new power supply? Which do you recommend?
Thanks again.

CoreTemp keeps saying: "CPU is overheating!" and then tells me to shut down. I did as it said. But it seems to say that EVERY time even when I berely turn on my computer. What should I do?

get a new PSU before you damage the rest of the parts. do you have a price range you're willing to spend?

let's verify the heat or power issue

shut down the computer and remove the side of the case

point a small room fan towards the open side, boot the computer and monitor the temperatures

also inspect all your fans to make sure they are plugged in and running properly

Geez, look at those CPU and AUX temps. . . . 82C and 90C that is the trouble. That Antec can probably run that equipment ok. Is your heatsink on right?

Temperatures with the Room Fan (on high) by the open case.
Are these temperatures acceptable?

Motherboard 44 C (111 F)
CPU 71 C (160 F)
Aux 79 C (174 F)
Maxtor 2F040J0 37 C (99 F)
WDC WD2500KS-00MJB0 40 C (104 F)

Cooling Fans
CPU 2700 RPM

Voltage Values
CPU Core 1.36 V
+2.5 V 3.22 V
+5 V 4.92 V
+12 V 12.03 V
+5 V Standby 4.97 V
VBAT Battery 3.02 V

Does it affect the temperature when the Computer is on the carpet? Must it be on a desk or something?
Does Cable clutter also affect the temperature? Can files be erased by overheating?
Sorry for all the questions....it's that it's just a big investment...
