Welcome to TechIMO.

What size PSU do you have? It sounds like that could be a possiblility

[Omardeth]

ya sounds like everytime your video card starts pulling it overloads the power supply maybe . are all your drivers up to date ? meaing the chipset and video drivers .

[blood]

What is a PSU (sorry, could you be more specific?)
And I have the latest drivers, Catalist 3.14....
I really don't know what to do, please HHEEELLLPPPP!

PSU = power supply unit. Might even be a rating on the back so you can see it. Should read 300W or something. What is the rating?

Cheers
Mick

Are you overclocking anything?

[blood]

I have all upgrades, DirectX9, everything is supported.....
Come on, is there any1 who can help?

Could be a memory related problem or something to do with the swap file on the hard drive. Check the event logs and see if any errors are being recorded. If so, post the Event ID here.

it sounds to me like you power supply is at its limit . if it is a 250 w supply . look on the side of the power supply and it will have a list that will look something like this
+3.3v 30A
+5v 50A
+12V 25A

post that . to me it sounds like you just are running it at its limit with all the things you have in there .
