Hi, sorry for writing this in English! My computer has been shutting down during boot up. It starts fine in Safe Mode, tho. Once I do manage to boot up (it took me 6 tries this time) the computer stays up .. so it's just a start up issue. All the fans are working ok and no problems with Ram or over heat issues. After a series of eleminations, I've concluded that it's a power supply issue. I need to buy a new one! My problem is I don't know very much about what power supply would be compatible with my rig. My current one is: FSP400-60HLN (24 pin). My processor: AMD Phoenix 9500 Quad-core processor, 2200 Mhz and I am running Windows 7, professional. I don't do any gaming, so I need something basic and inexpensive I thought I'd play it safe and just buy exactly the same one, but I couldn't find the same model anywhere! Is there anything similar to what I had that you would recommend? It would be great if someone would take a quick look at huuto.net and let me know if ther's any thing there that would be compatible .. this would really be highly appreciated. Any help or suggestions would really be great. Thanks in advance.
