First person to lead to the solution to solve my problem gets 5k credits, how about that? So... a few weeks back I was going about business as usual, woke up, got on my computer (on my day off) and logged into Guild Wars to do some farming... about 5 minutes into gameplay my PSU went *spark spark* (an Antec Trupower Trio 550w) and died. I thought, 'no biggy, I have been running my computer 24/7 for nearly 3 years, I will just go get a new PSU'. So I got a new PSU (BFG 650w) and plug it in, all the fans are working, all the LEDs are working, I am like, 'awesome' and then I realize I am getting no video on my monitor, at all, not even a hint that it recognizes there is an input. I think about it a little bit, figure that if the PSU sparked, it could have taken the mobo, graphics card or video card with it, all would give off the same issue. So I run down to the computer store the next day and get a new mobo (Gigabye p45 board, too lazy to find the box) and some upgraded ram (OCZ Reapers 4gb ddr2 1066 - it was on sale, bite me). I come home, plug it all in using my old video card (x1950xtx) and fans start up, etc. like normal, still no video. Now I am stuck with the decision of going to buy a new processor and video card. Today I ran out and got a new processor (e8800 up from e6600) and video card (evga 8800 gts) and plug them in today. I see no video, again. I decided to come back on my old computer (just swapped the monitor cables over) and about 5 minutes later, the fans stop moving and the PSU is unresponsive (and smells like it went *spark spark* as well). I manage to get the fans moving again when ONLY the 24 pin connector is plugged in (and the processor fan plugged into the board). I can't plug the 4-pin into the mobo for the processor, the pci-e 6-pin into the video card, or even the sata cable or the fans no longer work and there is no power. The reason why is obvious: for whatever reason, the PSU blew out. So, no credits for that answer =P. My primary question is what *could* this be, why isn't my video working (and I haven't heard any sound out of my speakers indicating XP starting up when I tried booting up, so no clue if the processor or mobo is even working, both are silent upon startup, no beeps) and how can I fix it? Keep in mind I have fully replaced the PSU, RAM, Mobo, Processor and Video Card with 100% brand new factory packed parts and the problem continues. Also, why did my new PSU blow out? It is well above the requirements of the most intense part in my system (the 8800gts).
Holy crap. When i was reading the top half of the post it sounded like a power spike, or the like. If it was a spike it would affect other things in your flat/house tho. The chances of 2 PSU's failing oon one system is pretty remote, and all the parts are factory new then coudl it not be somethign outside fo the system? Liek a power spike, or shorting out somewhere. Prob didnt help at all, but check other appliencers in your place. Like microwave clock resettign or w/e. Prob miles off but GL
To my knowledge nothing else in the house has been experiencing any difficulties whatsoever. When I was building the computer I put it on a different socket (the socket I normally use is occupied with the computer I am using at the moment). I tried two different surge protectors as well.
not sure how good BFG PSU's are maybe just bad luck that it died like that. I wonder if the PSU took out your hard drive? You could try taking everything out of the case and running the computer that way maybe something is grounding out.
Check to make sure you don't have any incorrectly placed motherboard standoffs shorting out the motherboard, check to make sure you have all the GFX card PSU connecters plugged in (should be two of them in the 8800GTS if i recall correctly), but other than that I can't think of anything off the top of my head that would do this.
It *could* be hard drive, but would taking out my hard drive cause a short in the system? The only thing I have plugging into the mobo from inside the computer is the power switch cord so that I can run the system after it is all hooked up, otherwise everything is sitting outside of the case. There is 1, and its solid in place.
have you switched monitors? Im guessing at this point could try disconnecting the hard drive and see what happens
I have not switched monitors, and would the monitor display anything without the hard drive plugged in (would it just display the mobo BIOS)?
Alright, I went and replaced the motherboard today (got a 790i sli ftw) and exchanged the PSU for a new one and I believe I know why the old PSU blew out. The Amps on the old PSU were about half of what was needed to run the 8800 I bought (should have tried using the x1950xtx first, I know). Long story short, the video is now working and the motherboard is posting, however I ran into another issue. Since I had a prior config on my system and the CPU has changed its requesting a CMOS change, but I can't change the CMOS as when I hit 'F1' for continue or 'Del' for setup the system thinks for a second and then shuts off. Any clue what I am doing wrong?
try resetting the bios shut the power off to the computer and remove the motherboard battery for 30 seconds, it should be ok then
Already did that, I am in the IRC with Logic's companies tech support and builders. I think I may just have a bad board. I tried each memory stick I have one by one, removed the battery and waited for 2-3 mintues and replaced it, booted it up, same thing. Now I can get into the setup menu, but about 5 seconds into the setup menu the board just shuts off...
the only other thing I would even bother to try is update to the newest bios but doubt it would work. Dem you got some bad luck I thought that cyberpower computer you bought was a pain to deal with it
Yeah, I know my luck with computers blows (this is the Cyberpower machine btw, but all the parts have been replaced since then ... more than once lol). I can't even update to the latest BIOS, I can't get out of the BIOS to windows to download anything or change BIOS settings or anything, as soon as I enter setup it takes about 5 seconds and the computer shuts down.
