I recently got a refurbished HP Pavilion 550 a209 Desktop. I've been using it for about 3 days with no problems, but tonight it suddenly shut down with no warning, giving me the message that it encountered a problem and had to shut down. Okay. I've seen that before on other computers, so I wasn't freaked out - until I attempted to start the computer again and got a message that no boot disk was found. I thought I'd try again. No luck. Same message.
Anyone have an idea of what happened or what I can do to fix this problem? It's pretty annoying on a computer I've been using for just a few days.
For background, I transferred files and programs from my old computer using a program called Laplink PC Mover (laplink.com). I've used this program three times in the past with no problems, so I really don't think that's the issue. Before transferring everything, I scanned for viruses, etc., to make sure the old computer was clean. Laplink will not transfer programs that are not compatible with the new computer. I have used it to move programs from a computer using XP to one using Windows 7 with no problems at all.
The computer is running Windows 10, which was already on the hard drive when I bought the computer. I did create a repair disk and a Windows 10 ISO disk before doing anything with the computer. It has BIOS version 126.96.36.199. I don't have other information about the computer at the moment.
I am currently running hardware diagnostics, but it has a way to go yet. I already did a memory test and the computer passed.
I could try to fix Windows 10 with the repair disk, but I don't see how that would affect the computer not finding a boot disk. There is an external DVD drive hooked up to the computer and turned on, but that wasn't a problem before.
Any help will be greatly appreciated. I have another hour or so left on the thorough hardware diagnostic testing. It passed the smart check.
