Hi All,

My computer has randomly started turning off by itself, it does not go to a blue screen, just shuts off if someone were to pull the power cord out. Over the holidays this started happening, I have made some recent changes to my computer. Hardware wise I installed a faster processor but the power consumption is the same. I went from a 4400 AMD AM2 Dual Core processor to a 5600 AMD AM2 Dual Core processor (2.2ghz to 2.9ghz same 65W). I figured it was my power supply so I bought a new one a 500watts rosewill, not an upgrade but a better brand name from my old apevia 500watts power supply.

Is it time to buy a new motherboard or what?

Any feedback and ideas will be helpful.

Thanks

*EDIT* I forgot to mention, I can get my computer to stay on for quite a while if I go into bios and let it idle for about 10-20 mins

And you had no problems before this upgrade?
Did you apply a proper layer of TIM?

Yeah, no problems before it and none after until around 4 days of use

I applied artic silver on it

Arctic Silver is good stuff, if applied correctly. If not, it is counterproductive.

I suspect your PSU is fine, since this problem happened with both supplies, but sorry to report that Rosewill is not considered a better brand. For future purchases, I recommend buy from the Good side of this list - What Power Supply should I get? How many Watts? Who made it? Guide Inside. - PCMech Forums

Other causes of sudden shutdowns include bad RAM, failing motherboard, leaky capacitors on the motherboard. I would start by inspecting the board for leaky caps. Here's my canned text on that.

Inspect the motherboard for bulging or leaking electrolytic capacitors. These failed or failing capacitors are a common cause of sudden, but seemingly random system lock ups and reboots. The capacitors look like tall soda cans, many of which surround the CPU socket.

All older motherboards, and many of today's less expensive motherboards use electrolytic capacitors containing a liquid electrolyte. Failing (including flawed and/or abused/over-heated) capacitors literally bulge at the seams due to excessive internal pressures. Extreme (and very rare) cases result in a firecracker type explosion that can really stink up a room. Typically, electrolyte just oozes from the pressure relief point, which appears as a symbol or letter stamped in the top of the capacitor casing. The electrolyte can be caustic to motherboards and flesh. Look for white to dark-brown, dried liquid or foam on the tops or bottoms of the capacitors. Bulging capacitors are a sign leakage is about to occur.

A motherboard with bulging or leaky capacitors can be repaired, but often it is more cost effective in the long run to replace the motherboard.

Be sure to first power down, unplug the computer, and keep yourself discharged by touching the bare metal of the case before reaching in.

I just ordered a new motherboard



thanks for the help
