Hi guys,
I'm having a similar problem. I've changed RAM and Video Card, and the same problem occurs. It's usually when I start playing games (The Movies most recently but it's happened on all games I've tried). Sometimes artifacts will appear on screen, sometimes my HD LED will turn on and stay on. Most often it freezes, but sometimes it just reboots.
Specs
Gigabyte 845PE-667 Mobo
P4 2.4b
512meg DDR333 (V-Data) RAM (also tried 512 and 1024 V-Data & A-Data DDR400)
Seagate 80gig HD
Radeon 9800 Pro 256meg, also Bioware GeForce 6200 128meg
Eagle 350w PSU
I've tried all different combinations of RAM and Video Card, and the same problem occurs. At first I thought it was overheating but after a few days of both the GPU and CPU having Arctic Silver applied, the same problem occurs.
I've forked out a fair bit to buy new parts (RAM and Video Card) thinking that it'll resolve the problem but no luck. The PSU is around 3-4 years old, could it just not be up to the task anymore?
There's nothing in PCI Slot 1, and niceboy, I'm not sure what SMPs are...?
Thanks for any help.
