Microsoft released Service Pack 3 for Windows XP on 5/6/2008. I decided to install it on my 7 and a half year old Dell GX110 desktop PC and it literally killed my PC. Or did it? After completing the installation, shutting down, and forcing a restart, my PC would not boot or even start the POST process. No output on the monitor, I could not access the BIOS. The power light was solid amber, pointing to a hardware, not software problem. The fan on the power supply was running and I even swapped out a spare power supply, but no success. The problem is either the motherboard or the processor. I bought this PC refurbished from Dell to use a my backup PC, and my primary PC is working great. I know it is a hardware issue, but it seems too coincidental that my PC croaked after installing XP SP3. There are tons of articles out there documenting problems with HP PC's that have AMD processors. I had a working Dell with an Intel processor, so it really does not explain my situation.
I have been procrastinating about building a new PC for myself. I have most of the less expensive parts already - case, power supply, video card, and SATA hard drive. It looks like I will be using part of my Economic Stimulus Payment for the more expensive parts - processor, motherboard, and RAM. Thank You Bill Gates!
