Problem - Graphics Issue?

[liamljr]

Hi All,

I’m stuck with this issue.

About 3 months back my Tagan PSU blew up.
As I needed a PSU ASAP I went over to a local rip off shop and got a 680W PSU (2x 19A Rails).

Thought this would be enough to power my rig:

E6300 @ 2.8
2GB RAM
2x 500GB internal Drives
Floppy
DVD-RW
ATi 2900XT

Anyways, the systems has been fine until two days ago.
I decided to update my ATi drivers to 9.4 Same old, uninstall drivers, restart, install new, restart done.

Was bored so I decided to have a blast on team fortress 2.
Playing fine for 30-40 minutes then I get some signal loss… o0
Check all cables on back seem ok so i restart the machine.

POST = fine, Boot = fine, welcome screen = loss of signal. Hard reboot = get into system get into team fortress 2 play for another 2 hours…

Stop playing the game decide to defrag the system, scans, and such… leave it on over night.
Wake up fine, still on.
Turn it off go to work. Come back, turn on, no life… ARRRGHHHH!

Ok, Graphics card out, Take it apart clean it up and put some new thermal grease on…

Now, I get signal for about 10-30 seconds image is fine, but then just goes blank.

What do you guys think is causing this? Sometimes it’ll only display in POST, Sometimes it’ll get to the welcome screen in XP.

Heat issue? Power issue? Card issue? Something else? (Motherboard, CPU)…

I was going to buy a cheapo card like a X800… But the thing is they’re not that power hungry so wont stress the PSU.

Thanks,

Liam

Is there a possibility of testing parts in another machine, including the psu.
Not sure what else to suggest

As mentioned above by RJC testing the card and psu in another machine and vice versa would be the simplest and most obvious starting point.

The only other option available is to dismantle your machine to it's bare minimum and and see if the machine will boot up normally. If by some chance it does boot up on a skeleton setup you can at least rule out the gfx card as the culprit (maybe) - but saddly not the psu as it could still be a juice issue. However, you would get the oppurtunity to troubleshoot other components for a possible cause....

Good luck with it.
