Hello, I recently have upgaded my computer. all around...and lately I have experienced some wierd occurances with it. For awhile my computer used to restart a lot, and other times the video would freeze on it. Last night it frozed while playing Everquest 2, and I had to do a complete surge protector shut down because the power button wouldn't even work. When I booted it back up, it would not show a picture...BUT..i have taken the video card out and it works perfect in other computers...So its NOT the video card. Everything seems to be running, and I have been wondering if its the PSU. Here are my Specs

AMD64 3000+
Jetway S77MAX Motherboard
512 DDR 2700 ram
Radeon 9800 Pro 128 mb
300 W power supply

the 300 w supply makes me wonder if it is a power problem? but why all of a sudden would it not work now when before it did?...tell me your suggestions please, it would be most appreciated. thanks

Using XP?...anything in the system logs about the shut downs?
Disabled all non-essentials whilst gaming? AV& firewall etc (if offline)
Failing that...I would guess at a system memory prob here....
512 DDR RAM in one stick or two x 256?
If the former try another known to be good stick. If the latter remove a stick/swap 'em about until you find the dead/dying one.

Edit=typo :knock:
