repair or all new?

[dwsindy]

Current system is a
Asus p4p800-e MB
Intel p4 2,8ghz
2 80 GB WD IDE drives
ati radeon 9800 aiw pro 128mb
corsair twinx cmx256a-3200LL

Yesterday when I went to use the computer the monitor was blank. I rebooted and the pc booted up but the display on the monitor was very hard to read. I rebooted again and this time it would not boot up. I changed graphics cards and still would not boot. I have checked the hard drives in other pc's and all is ok. Any thoughts on what could be the problem? . I know this system is getting long in the tooth . Should I just rebuild a new system. I use the pc mostly for office work and photoshop. Any thoughts on a new build? Thanks

Might be a PSU issue. Or maybe the video card.

With the advent of multi-core systems, a new system would vastly speed up your Photoshop work.

i'd say all new, but you could start with the new power supply and see if that fixes it. either way you need a power supply, so nothing lost.
you can of course reuse you case, keyboard and the like.
I'd get a new HDD, sip the oldies, and confirm your current vid card is good, then craigs list it. good AGP cards seam to be worth a bit
