System will not Power Up

[Rezident]

System was working fine the other day, today it will not power up. I tried a different power cord, plug etc. is there anything else simple that it could be before I go ripping out the PSU?

Could it just be the front panel power switch? Is it safe to use a screwdriver to connect the two PWR headers like you can to clear CMOS?

Any other suggestions gratefully accepted. Cheers.

Paperclip trick will come in handy, hadn't heard of that before, thanks I'll try that as I've never had an issue with the PSU and think it is the least likely source of problem. Thanks.
