|A few years ago I built a PC with a fast, water-cooled CPU, lots of ram, and a big hard drive. Basically, I made the best desktop/development computer you could for around $1200 at the time. Some things happened since then, and it's not been used or even turned on in a couple years. Now I want to use it again & when I hooked it up & pushed the power button, it came on for a second, then turned off. It just won't power up anymore.|
I haven't been inside a computer since I built this one, but I'm no stranger to them. I'm 37 now & built my first one when I was 13. Anyway, so I've done everything I can think of to troubleshoot this problem: blew out dust, reconnected power cables, disconnected all peripherals (even hard drives, CD, etc.), reseated RAM, removed RAM completely, removed CMOS battery, nothing has worked so far. Obviously, searching online hasn't provided any suggestions that have fixed my problem either.
At one point I was able to get it to boot up & it got to the BIOS & started reading the hard drive & Windows said it had detected a failed startup and it was going to try to fix the problem. It said it might restart itself multiple times during the process. I left it for some time while it claimed to be fixing it. I left the room & when I came back, it was off. I powered it back on & the same thing happened, Windows detected startup problem & was going to fix it. I left the room again, for just a few seconds this time & when I returned, it was off again. I tried again, but from this point forward it won't power on at all.
The hardware is a few years old, but it's all still in very like-new condition. It only had only been used for a few months before being put in storage. I would be extremely surprised if any of the hardware components (PSU, CPU, RAM, Fans, etc.) have failed causing this problem. I don't have any extra components (spare CPU's, PSU's, etc.) to swap out to test, but as I said, they are quite new and it is very unlikely that they have failed already.
What should I do to get this thing running again?
