also if I attempt to pull out and replace psu should I be removing chip and applying some thermal paste to it at same time ? I have some artic silver here.
You shouldn't have to remove the CPU or heatsink if you're removing the power supply. Simply unplug all the connectors, remove the screws that latch it from the back of your case, and you're all set.
The only time you should really need to replace that thermal compound is if you have removed the heatsink and a reapplication is necessary or if your temperatures are strangely high (due to improper application/seating of the thermal compound or heatsink).
Aside from that, even with some craptastic brand PSU, you should be able to at least boot up in stock settings. I'd make sure that you can do that at bare minimum.
Edit: If you're not using it, download "Real Temp 3.6" and let us know the temperatures you are getting while running Prime95. Curious if you're system is shutting down to overheating as running Prime95 by itself usually gives a warning before anything weird happens.
Also, use a program like CPUID to monitor what your CPU settings are indicating (clock speed and multiplier, etc).Edited by jivenjune - 5/27/11 at 4:01pm
