I just had upgraded my pc from:

Video Card: 9400gt 512mb -----> GTX 460 768mb
Motherboard: ECS G31T-M7 -----> (No Change)
PSU: Generic -----> HuntKey Max700w
CPU: Intel Pentium E2200 -----> (No Change)
Ram: 1 (1gb) and (1) 2gb -----> (No Change)

My PC was perfectly FINE before i upgraded. Could someone tell me what's wrong??? I've been reformatting three times already but no luck....

You need to tell us when it is freezing, i.e. randomly or when you are doing specific things.

Randomly it always happen during boot and startup and sometimes when i leave my pc on for the whole night downloading.

1. What is the make of your harddrive?

2. What security software do you have installed?

3. Did your PSU come with your case?

4. Did you update your video card drivers?

How do i post when my problem is solved?
I Just warrantied my videocard and everything was okay now and i also got a Q8400

Just let us know if it is solved. The nods will do the rest.

Yep its solved

Good for you! So the video card was bad afterall. Interesting because those 460 cards are nice

Thanks much for letting us know.
