newer PC problem...

[jmc]

Might be rambling on, sorry in advanced.

So last night, upgraded to a new motherboard....new processor (Intel Quad 2.6 ghz) and a new video card (GForce 6800 GTS 512 MB). Hooked everything up no problems, installed windows xp...drivers the usual stuff. I then noticed, that my case was getting kind of hot (internally) so I rechecked my fans, and turns out I forgot to plug power into the graphics card (grr.... but even with power not plugged in the video looked fine).

Once that was plugged in, my computer would turn on for a bit and just shut itself off. Since my PSU was 450w, I figured it was just not enough power for this equipment. I grabbed a 600w PSU while picking everything up, so I install it with no problems.... and go to turn on the computer, and it powers on with no video at all (graphic card fan is going normally, just no video) so I start fooling around with it, with no results. I then think my graphics card got fried somehow, and decide to try my old card (PCI-E ATI x700) and I have the same results.

Did I manage to fry my motherboard, or maybe im missing something here?I bought the stuff last night, so I can easily return it..... would I be better off returning the Mobo only, the graphics card only...or both?



*Cliff notes* New Mobo, New Graphics Card, New Processor....worked fine, until I installed new PSU and now no video to display. Also, the HDD indicator light stays on full time now.

I believe it's the PSU. I had this problem myself a while back. Never really understood it. When I rebuilt my PC I also installed a newer 600 watt PSU, since my old one was only like a 300. PC turned on, black screen, won't post, just sits there with the HDD access light on. The PSU was a 600 watt thermaltake on an MSI mobo. They didn't seem to like eachother too much. So I picked up a cheaper 450 watt Enlite PSU and it worked perfectly.

I dunno if it's a compatablilty issue or what with the 600 watt PSU. I'd try a different PSU, maybe a 500 watt of a different brand.

Ok, ended up being a bad PSU.... so upgraded to a 650w PSU thats "designed" for SLI cards, and Quad Core processors.....

So I installed it, and turn it on.... boots up normally, but after 3 minutes it shuts off completely (kills power)

Any ideas?

You probably fried your processor and motherboard by using the old PSU.

Best Bet: replace *everything* that you had plugged into the old PSU, and the new PSU (possibly messed up by the fried components)

[Avanarius]

do you have all your supplementary power plugged in, and all that jazz?

I don't really know what to recommend except trying other components.

Also, how did a quad core end up with a 6800? Wouldn't that be just a wee bit of a bottleneck

Not for FFXI though >_>

Err... thats the 2nd time ive put a 6800, its really a 8600 GT.

Problem is all set anyways, I guess it was just 2 bad PSU's. Went out the other night, and bought a good 700w PSU and everything works just fine.

How is that 8600GT working out for you? Can you play FFxi on max settings? I ask because I bought an 8600GT about 2 weeks ago and have yet to install it(I'm soo lazy ).

Pretty much everything can be played on max settings...... however I guess I can barely play crisis lol

but havent really done any "hardcore gaming" with it yet... just been playing ffxi, and Half Life 2. Both those games can be played on max settings, with no framerate issues that ive noticed.

[jmc]

Downloaded the Crysis beta... playing it in medium settings, and works very very well with the 8600 GT.

Double check the heatsink on the CPU.
