PC shutdown but Is still on?

[Lone_wolf_S117]

I was playing Battlefield 2 and all of a sudden my screen goes dark. at first i thought the power had gone out again (livening in CA,USA, or power grid is not really good) But my screen power button was still green and stayed green, its suppost to go orange when the pc shuts off. Then i realized the power in my room was still on and my G15 keyboard on laser mouse was still lite up. the only thing that look off was my tower. no fans were running, and the front 2 LED lights were off. then about 2 min later the tower hums back to life (lights and all) and my screen goes right back to Battlefield 2. and about 10 secs later, the game crashes and vista tells me my hardware maybe over heating. Now, this PC is almost brand new. only 6 months old. this is the first and only time this has happened. Can anybody tell me what happened, its in the shop right now being looked at but the guy at the shop said he never heared of a pc doing this?

Its DX 9 (tho vista supports DX10) and i cleaned out my pc about a month before this. shoot it will the air hose and shotvac. I know it didn't over heat, my temp showed it was running at 90F when it happened. And i just got i back today, guy at the shop said nothing looked wrong but since my pc got a warrenty, i got a new motherboard for about 5 buck (USA money)

 

PSU: 450 watt

ok cool.

is the issue still there.

i take it your card supports direct x 10, try updating to that,,,the newer vista games reqiure this now....

and 450 watt is ok,if it is running a lot more hardware.

no, it hasn't happen again and the guy at the shop think it may of been the mobo (motherboard) or cpu, so he gave me a a new mobo and cpu (same make as the last cpu and mobo) since i have a year of full coverage on this. Its hasn't done it again, but if it does, what should i do?

[danzil]

take it back to the shop,and explain this to them,,

saves your money,

ok, well, i hope it was jus tje last mobo.

[danzil]

yeah well you have your warrenty on the replacement board as standard,so if it happens again they wil have to repair it.....not sure of there terms but usually 30 days on labour and 1 year on parts.
