[Joman_X]

I have a core 2 quad q6600 @2.4
6gb DDR2 ram
120gb SSD
1TB HDD
Blu-Ray drive
can i run a gtx 570 EVGA HD 2.5gb on this psu? (CIT pentium p4 500u)

Geforce recommends at least 550w PSU so 500w should be okay as long as it's a reliable brand like Seasonic, Corsair or Antec.

GTX 570 requires a 550W PSU with 35 Amps (420W) on the 12v rail & 2 x 6 pin-PCIE power connectors

CIT aren't a brand i'm familiar with. And given the age of the system that this generic PSU shipped with, i assume, it likely wont be good enough to meet the requirements TBH.

Would it work as a 2 to 3 month temporary psu or is it unpredictable? (The power supply has had about 100 hours of overall use max)

I'd be surprised if it powered it TBH, it's not a great brand & the 12v rails look weak with dual rail 13A + 14A (Note: you can't add them together to get the total amperage). You might get away with a modern, low powered card like a GTX 750, one of the models that doesn't require any additional PCI-E power connectors.

Bottom line, i wouldn't recommend using that PSU with a GTX 570.
