What I got (that I think matters to my situation, anyways) – Motherboard - ASUS P4S800 Videocard – ATI Radeon 9550 256mb So. I just bought a new Codegen Briza-63-CA case and a Zalman CNPS7700-ALCU 92mm 2 Ball heatsink. I switched everything I had into my new case, and attached the new heatsink during the process. After I got everything connected and ready, everything powered up, except for the monitor. It says ‘no signal’. I was pissed. I still am. To troubleshoot the problem, I took everything out of my case and tried to start everything while it was laying bare on a big piece of cardboard. No luck, so I don’t think this is a grounding issue. I also know my monitor works, as I tried it on my roommate’s computer. I don’t think it’s the videocard either, since I tried using his videocard in my motherboard as well, once again with no luck. I also reset the BIOS (or I think it’s the BIOS, anyways) by removing the battery from the motherboard and switching those jumpers around for a couple of seconds, then replacing everything. THE ONLY changes that I made to my motherboard while I switched it into a new case was that I noticed that the jumper on my harddrive was sideways, so I just straight up removed it. My dad installed it way back when. I don’t think this would matter anyways. ALSO, I removed two jumpers that were on my front audio connection, as this new case I got had front audio connectors, and those jumpers were in the way. Once again, my dad put this together like 3 years ago, and has no idea if he put those there or if it came like that. Anyways, I don’t really think this would make any difference as well. I suppose the new heatsink is also something that I added, but I tried booting up the comp without it attached as well (is that a really dumb thing to do?), with no luck. My AGP slot could be broken, but I like to think that is not the case. It doesn’t look like there has been any damage to my motherboard, either. It still almost looks brand new. I’m running out of ideas here, guys. I could bring it to a local store where they say they would run a ‘diagnostic’ on it to see if anything was wrong with it for $30, but I don’t even know what that really is or what the procedure for that is, and I would rather try and talk to you guys first before I go out spending money. Any help is greatly appreciated. Thanks.
