First timer here. I opened the case of my computer (Compaq Presario SR1135CL) to blow out the dust and now it won't even power up. The power supply flashes "GREEN" on the back, so I went to Compaq's website [https://h10025.www1.hp.com/ewfrf/wc/f...name=bph06788] to troubleshoot. I got down to the end, where they diagnosed the Motherboard (A7V8Z-LA) or the CPU (AMD Athlon(B) XP 3000+ 2.10 GHz), as the likely culprits. Both are kinda pricey, especially if I don't know which one is likely to be bad. I called the local PC repair shop and was quoted a price of $69 to troubleshoot. It's a fair price, but they said it would be a few days before they could get to it. Any suggestions on how to narrow down the possibilities? And where I could locate inexpensive (i.e. CHEAP!) replacements? Thanks!!

What did you use to blow out the dust? Its likely you blew something into somewhere. Like under the cpu, ram, video card... or just knocked something lose. I would get me some thermal paste, remove the cpu, ram and all cards re blow it out paying close attention to the above mentioned areas making sure to really get em blown out. Then some new paste on the cpu (2 small drops spread around even over the top). Dont forget to blow out the inside of the psu. If you did it before this is a good area for dust bunnies to get stuck. So give em another try. Good luck

I have a rather small P/S of 250 watts. The CPU is AMD Athlon(B) XP 3000+ 2.10 GHz and the m/b is the A7V8Z-LA. It has 512 MB RAM and on-board video. I press the "ON" button and nothing happens. I reseated everything, but still no action. I'm replacing the P/S (cheapest component) with something bigger, hoping it will solve the problem. I can't check the bios, cuz it won't boot....
