Hi, I was fixing my Dell PC a month ago (Dimension 4600). It lasted me sooo long! I was changing the graphics card for the third time when my little brother spilled a thick, yet 95% solid substance made of plasticine and water, while it was on. It spilled on the SB, and after that, I let it dry for two days, then put it on. Oh wait! It only comes on when I plug it in, no diagnostic lights and the power button is orange. No POST. If I press the power button it comes off. If I press it again nothing happens unless I re-plug it. Maybe my board spoiled. OK, I have an extra one. BUT DELL parts are proprietary! So to change the board, I have to change PSU, Case, Fan, and who knows, maybe the CPU too. Don't forget heatsink! So the sad Dell is sitting there doing nothing while I took out the drives. Luckily for me I had a spare malfunctioning computer that could do the job. Buying new parts is out of the question (my country has lots of Dell stores - but they are expensive. Why can't you be like HP? The computer was purchased in 2004, so no warranty again. I can safely say one thing: Whether or not something is fixed, I'll never buy a Dell again, simply because of your silly proprietary parts. So here is the question: Can someone help me? I do know Vista - and I have another PC. But computers are not your everyday grocery item where I live. I did remove the stuff.
