hey guys, i was wondering if any of u might be able to help me out with a little problem i'm having.

in my aluminium case i had a 300 watt psu that was crap, my dvd writer kept stopping and spinning when the computer tried to boot so i returned it and got a 500 watt instead. now i live in south africa and around here people dont usually fuss about brand name psu's and the one i got was a procase 500 watt. being 500 watt i thought it was of good quality.

anyway, my system (sig) started acting funny recently when i overclocked my cpu. but before i even oc'ed my cpu my 9800 pro started artifacting at stock speed so i had to underclock it. now sometimes i can oc the cpu to 3.12ghz and have my radeon at stock speed and still be able to play farcry for hours with no artifacts. next day artifacts appear immediately.

also a new problem that has crept up is random lock ups of the pc. just like freeze frame, no num lock, mouse cursor is cemented etc. when i reboot sometimes it just doesn't boot and other times it gets to the windows log on screen and freezes there as well. it does this at stock speed as well as overclocked.

here are the specs for my psu -

+5V - - 45A

+3.3V - - 28A

+12V - - 25A

-12V - - 0.8A

-5V - - 0.5A

i have tried upping the vcore to 1.6, the ddr to 2.6 and the agp is always at 1.6. i put my mem on 333 and then up the fsb to about 240 when overclocking.

any ideas?

Your sig didn't show up - at least for me. ?

As for artifacting - this is going to be from your video ram being overclocked too high.
For locking up, this is your Video core being oc'ed too high (or your cpu, but I'm pretty sure its your v card.).

A lot of this may be just a video card problem - are you 100% sure you have the card you think you have (not what was claimed to be sold, but what you actually have)?

I'm not sure how you could test if the PSU is causing this or not, perhaps removing 12 volt components or downclocking the cpu while keeping the GPU at a setting that gives artifacting, and see if it does/doesn't go away.
Also, dont use farcry to test the artifacting - use 3dmark03, or theres some other rendering prog i'll find later and link that you can use (just dont have time atm to link).
 
pretty sure my card is a Sapphire 9800 pro. it says so when i install the drivers and all that and it ran fine for about 4 months before it started going funny.

i also suspect some kind of heat problem with my videocard ram. ah well. i saw some guys in other posts saying that a bad psu could lead to all kinds of problems and i was just wondering if mine was alright or not.

Honestly, if you have a little extra money, i'd replace that psu as soon as possible. You may have already crossed the threshhold of when a psu begins to fry hardware. You're getting classic symptoms in my book.
I may be a bit of an alarmist but i value my hardware and i wouldn't turn that pc on again until it had a different (better) psu.
