Hi everyone Comp specs: HP Compaq Presario CQ60 Notebook PC AMD Athalon Dual Core QL-62 2.00 GHz 2 GB RAM 32 bit operating system Windows Vista Service pack 2 The computer shop is not able to help me with my computer so I'm on my own. My fan went out so I took it in for a replacement fan. When I got it back I tried to play a game and it crashed after 10 minutes. Black screen and computer just shuts off. I've seen a BSOD a couple of times on startup. It's gotten progressively worse as flash games crash it, now megavideo will crash it. I tried checking the RAM with memtest86+ and it crashed. Someone suggested underclocking and when I tried to get into the BIOS, crash. I've done all virus checks and defrag. I updated my NVIDIA drivers. Speedfan is not helping me as its reading lava hot temps when my comp is cool to the touch and the new fan is running fine. When it crashes it seems slightly warm but I can't understand why it ran fine with the dinky fan it came with and but now that I have a new one it would overheat. I do not think it's the PSU because this all still happens on battery. I was going to use 3D mark to test my VID card but at this point I just know it will crash too. I was really hoping it was RAM but now I think it might be fried caps on the mobo. I'm getting ready to take my comp apart and look. I can only really afford to fix the problem the first try on this, a new comp is not an option right now. I am not a computer genius but I'm not an dummy either. Any advice is greatly appreciated, I am at my wits end with this.
