Having problems with your PC Desktops ?

Asus Pc power supply

\015 Hi there. I have an ASus desktop (which runs my cctv network).\015\012\015\012This died about 2 weeks ago and it seemed that the power supply unit was the problem. It was a standard n Asus 4s-435 which is a 350w unit i believe.\015\012\015\012As it was a 'hurry job' I purchased a stanard 650w power unit the same size and installed it assuming 650w was plenty spare and would not cause any problems.\015\012\015\012However the PC now boots up for about a minute , showing the screen and then shuts down again continually.\015\012\015\012Am i being stupid? is this because of the oversized power unit 650 vs 350w, or something else?\015\012\015\012any help appreciated.\015\012\015\012toby\015

Sounds like heating problems. what i'd recommend is to go buy some thermal paste, remove your heatsink/cpu fan. wipe the bottom of the heatsink clean with a cloth, and do the sam with the top of the cpu. now apply the thermal paste (about 3mm cubic or whatever the packaging says) to the centre of the cpu, and secure the heatsink/fan onto the cpu. make sure your heatsink is on your cpu SECURELY. In my experience a pc that boots up, works a while then reboots out of it's own is having heat problems. especially if the pc wont boot/reboots quickly after the initial reboot.
