The other day I bought Battle Field 2 and installed. When I tryed to reboot nothing would happen, it wouldnt even post. I dont think it was Battle Field 2 though, because I was getting warning that my video card wasnt getting enough power. I take an old 400w generic psu I had and put it in, with only my video card, my mobo and harddrive plugged in. It will post (most of the time) I even got into windows once, but it still dosnt work most of the time. Either it freezes at the windows loading screen or it wont post at all. I thought it might be the weak amps on it, so I try my dads Antec 350w, with 21 amps on the 12v rail. Still didnt work, frooze on windows screen. I tryed to plug in my cd drive to run a repair off the windows disk, but it wouldnt boot with it plugged in. It seems like a power supply issue to me, but it may be something else. I even tryed combinding 3 psus together to run it, one for my mobo and video card (the generic one, rails are pretty good on it when not under load) one for my harddrive (250w from an old emachine) and one for all other crap, fans, cd drive (my old one, still has enough juice to power little things) and it wouldnt boot. Would this have to do with something other than my psu?

PS: I got BF2 just sittin there and I cant play it, making me so mad! .

well..if you tried a few different PSU's with the same result, I would think it isn't a PSU issue...

just from the little bit of info... it maybe a mobo issue.... bad voltage regulator? something like that.....

Thanks for the fast reply, what more info do you need? And also how would I know it was a motherboard issue? I was planning to upgrade, but not so soon! I need ot save up.

its a guess... did anything else change....

you tried 3 PSU's if I understand with the same result for all... that would eliminate the PSU...

it is booting and then stopping.... it could be some drivers...Windows tries to load a bad driver and then quits

Hmm... system quit with the CD rom drive... would it boot at all with the CD??

something may be unplugged..
does your board have a seperate 12v (4 wire) plug and if so..is it plugged in....

It wouldnt boot with the Cd drive plugged in, I can try again though. Like I said I did get into windows twice, both times I got a "video card not getting enough power" message, so I went to reboot and tryed a different plug, then it wouldnt boot again. My board does have the 4 wire plug, but it is plugged in. I installed BF2 before it quit working, so maybe it installed some bad drivers? I will try to get my cd drive working and run a windows repair.

BF2 wouldn't do that....

Hmmm... so the vid card has worked perfectly in the past?

Yes, but I think my psu couldnt handle it anylonger. It was kinda weak, it was a soyo raptor. I did have to rma the video card once for a loose capacitor, but besides that its been good. It works in my dads computer I think. I took multimeter readings of it while it was running, the 12v and 5v rails seem fine during boot and when it freezes at the windows startup its still steady. Does this mean its a motherboard problem. Half of the time it dosnt post at all, then if it posts it freezes at windows startup. If it meraculusly gets past windows start up it gets into windows. Its gotten into windows only twice in the hundreds of times ive tryed.

EDIT: I plugged the psu, my graphics card and my harddrive into my dads computer and it seems to be running alright. So that means its mobo problem right? I was thinking it might be the ram. Would bad ram do that?
