Hi all Ive recently upgraded my pc i'm currently having trouble since upgrading with computer reboots etc Ive wiped it clean once and installed xp fresh and im still having problems. Is my psu able to cope as its blowing out warm air & seems to be nosier since upgrading from a 4200+ Athlon & 7300Gt gpu my temps are as follows


My system is
Amd Athlon 6000+ Cpu
Radeon 4850 Gpu
3gb Ram
160 Gig Hdd
asus M2v motherboard
Corsair vs450w psu
Coolermaster cavalier 3 case

Any help would be much appreciated
 
How did you seat the Heatsink, did you use arctic silver or just the stuff that came on it from the store?

Download and install Speedfan (see sig) and tell us what sort of temps you are seeing.

That PSU may be a little under powered for that setup also, got any spares you can test it on?
 
Can you provide more details? When is it rebooting and how often? Blue screens, or is it just restarting by itself? List your temps while idle and under load as well.
 
Hi sorry for the late reply pc seems to be ok temps at mo are
Temp 1 32oC
Temp 2 34oC
Temp 3 -128oC
HD0 44oC
Core 33oC

i was worried the psu might be struggling its a corsair vx 450w

I seated the psu with ShinEtsu Microsi thermal paste put a rice size on then put Zalman fan ontop of it am i supposed to spread the thermal paste?
 
Yes it has to be spread very finely (till you can almost see through it)

Although you seem to have gotten away with it, yeah i'd say its the PSU probably too small then
 
My thoughts on power supplies...Related to the negative effects of heat on the computer.

Manufacturers test their PSU's at a set temperature...from this their rating is determined... for most this No. is 25 degrees Celsius...which falls short of the temperature that most computers are capable of achieving.

Given that a PSU will actually lose 2-5 watts per one degree of heat above the 25 Degree Celsius testing temperature...coupled with the fact that computers tend to run at 10 degrees higher than room temperature... In the summer time when the room temperature can easily reach 80 degrees F... your computer will be running at 33 Degrees C. or 90 Degrees F.

So the...math can make...your 500 watt power supply into a 460 watt unit.

In addition to this...what needs to be taken into account is that each degree that your computer components are operating at...under powered...adds more heat to the equation.

The above has not taken into account...the issue of high quality vs poor quality units...Power supplies convert voltages from wall outlets to lower levels used by the PC. During this conversion, some power is lost as heat. The efficiency level of the PSU determines how much extra power must be put into the power supply to run the PC. A high quality PSU can help reduce the noise and heat generated within a computer system. The higher the efficiency rating the less heat the PSU has to deal with.

Therefore heat is the computers enemy...The hotter the temperature your PSU is forced to run at...the poorer the supply of power the rest of the components will receive...which has been known to lead to such things as crashes, freezing, rebooting, BSOD’s, and video distortion, as well as partial and complete failure of other components.

The fact is very few PSU’s are capable of producing the wattage that the companies advertise.

PCI-E requires 26 amps at 12 volts. That's a 650W...Quality...PSU.
 
Yep, there's a good chance the power supply is the issue, especially with the new video card since it requires more resources. Check the video card temps, and run memtest86+, just to rule out some other possibilities.
