Have you checked that all of your power connections, expansion cards, graphics card and RAM are properly seated in their respective connectors?

If you have spare power connection cables available, try swapping them (one at a time) with the ones that you are currently using.
I've had dodgy cables from my PSU cause problems in the past.

Remember to turn the power off, BEFORE messing around with the connections and other parts.

Observation

I just noticed that the screen clips from Everest listed your bios as "0701". When in fact Asus says the current bios is 2701.

ASUS - Motherboards- ASUS M3A78-EM

Just something to ponder.

I replaced the PSU about a week ago, it was a no name 370w that I had in there, and I replaced it with a 650w PSU, and it's still the same problem. I will check all my other components though. Thanks

Ok, thanks, I'll look into that. I've never updated BIOS before, so I'm sure I'll learn something there, thanks

This will show up any cooling issues.
Here's a screenshot of my temps while running Prime95 after 10 minutes, they stayed at this until I turned it off.

Please post back a screenshot of your maximized Disk Management drive map and listings:

1. Type Disk Management in Start Search box.
2. Open Disk Mgmt. window and maximize it.
3. Type Snipping Tool in Start Search box.
4. Open Snipping Tool, choose Rectangular Snip, click New, draw a box around full drive map and all listings.
5, Save Snip, attach using paper clip in Reply Box.

Tell us what is on each partition.

I'm not entirely sure why there's 4gb and 9 mb unallocated on disk 1, but it's been that way since I've had it (I got it off a friend of mine ages back, it's never bothered me)

Obviously disk 0 is operating system. the other 2 are just stuff (movies, music, pictures and one or two games)

based on that site I need a 372watt power supply. I had a 370watt, now I have a 650w...

Ask back if you have any questions before updating the BIOS since it's a critical operation which you must get right, without power loss.

The temps need to be addressed. Have you cleaned all the dust out of your PC, including the heatsink?



If you need to pull off the heatsink to do this thoroughly then you'll also need to repaste your CPU with thermal paste. This should be done every year or two anyway since the paste dries out. To learn how to do it google for videos like this to watch enough of them you understand it fully:



Remember not to do this on carpet, and guard against static charge to mobo by constantly touching the case before reaching inside, avoid touching electronics as much as possible and do the cleaning and paste operations away from mobo.

Ok, thanks for the help, I'll get onto this tonight.

Ask back if you're unsure because these operations can be unforgiving.

The issues of shutting down are IMHO being caused by your cooling is inadequate. Either replace the fan and heat sink or at least replace the heat sink compound. The maximum core temperatures for that CPU are :Product Specification: Processor AMD Athlon™ 64 X2 Dual-Core Model 6000+ Mfg P/N ADX6000CZBOX / ADA6000CZBOX Operating Mode 32/64 Stepping F3 Frequency 3000Mhz HT Speed 2000 Voltage 1.35-1.40V Max Temp 55-63C Thermal Power 125W L1 Cache 128KB x2 L2 Cache 1MB x2 CMOS Technology 90nm SOI Socket Socket AM2 Warranty 3 Year Manufacturer
