Okay now I'm kinda a real noob when it comes to computers and how they work. But so far for the 6-7 months I've had my computer (nothing fancy, just cheap at bestbuy :D) I've had 0 problems, none. Now I just bought this video card... it's called GeForce 8400 GS (I know still nothing super good but better than the current.) So yesterday I installed it and set up everything according to the disk it gave me. I was playing WoW and everything normally. When I woke up this morning I wiggled the mouse to bring my comp away from sleep mode, but nothing happened. It showed the pc was currently on, but wouldn't respond. When I pulled the plug (wouldn't shut off otherwise) and tried to rebooting it, all that it does now is start up for about 5 seconds, nothing shows up on the screen, and then it shuts off again. It'll continue doing this forever basically without me even needing to touch anything after the first try. If any of you know how I can get my computer working again so my parents don't rip my head off, that'd be very helpful :D. Oh btw, my system currently runs 250w, and the card says it needs 300w minimum, could that be it?

Maybe ... if you don't have enough power supplied to your computer, it simply will not boot up.
-
alright well now even when I take the new graphics card out, it still does the same exact thing. :(
-
Probably new card disabled on-board video in BIOS. Enter BIOS, and check.
-
How do I do that in about 4 seconds of the computer being on? =/ Nothing shows up on my screen so I can't really enter anything that I know of.
-
If you're able to, look at the bottom of the screen for something like:
Press some key to enter setup
Pressing "some key" will get you to BIOS.
-
Unable to, the thing isn't really that the video card is messed up, it's the actual pc that doesn't stay on long enough to get to that part.
-
Did you triple check, you didn't messed up some cables inside while installing/removing video card.
Try to re-seat RAM.
-
Okay I'll try that right now, I'm reaalll sure that I didn't mess up cables though because like I said yesterday it worked fine with the new graphic card, just today my pc is bein a jerk.
-
new PSU. sounds like you might have pushed your old PSU a little too far...
-
Good point...
-
Sorry, may I ask what a PSU is? Does that stand basically for power supply?
-
yes, power supply. most are designed to give out a bit more then their rating... but not for long.
-
Make sure to check your +12V rails, 19A would be a safe bet, as that's what I have and I used to use a 8500GT now using a 9500gT which worked fine with that type power supply which was a Hipro at 300 watts.
-
How do I check those? I bought a 450w power supply and it still does the same thing lol =(!.
-
To be honest it almost seems like there's something.. blocking the power to reaching the whole machine, if you understand what I mean by that at least. When I turn it on with the side case off, I see all 3 fans (including the one to the graphics card), I hear otherthings start too, even now with the new PSU it seems the monitor turned on, but then said it's entering sleep mode. Still, if anyone has an idea for me to try that'd be great!
-
Can you log into safe mode and disable powersaving features?
Power saving doesn't really work well on most desktop computers.
-
I would try, but my comp doesn't boot up far enough for anything to happen. Currently stops maybe right before anything would start showing on the monitor.
-
Which output do you have your monitor attached to?
-
Hands up who thinks that he/she should unplug everything possible and start working up from scratch. I.e. Plug just motherboard & RAM in and see what happens (assuming original graphics card was internal or internal is present)
