I have an older intel core 2 duo desktop, its a custom build and its acting up a bit. I just recently started using it again for work from home with amazon. This board was in a micro atx case with a 350 watt bestec psu but has now been transplanted into an older case that has a powmax 400 watt psu. When I turn the pc on if its cold (as in shut off for some time) it will come on for a second, then power off, i have to flip the switch on the psu, flip it back and repeat this 20 or more times, at some point it will stay on, boot and run fine with no issues at all. Now for the weird part, if i remove the pci-e x16 video card, it boots and runs fine from first press with no issues. I have an old radeon hd2600xt 512mb card in there and thought maybe the card was bad so i stole one from another pc, a geforce 8600gt and it does the same thing. My next logical conclusion was its gotta be the psu and I have not tested this yet with another one, how ever without the separate video card and using the onboard intel 945 (yuck, cant even watch netflix with this) it will run perfectly fine with no issues. Also had this psu hooked up to a msi microatx board with amd e350 apu with radeon 6310 graphics onboard, runs flawlessly with no issues. im concerned its the pcie slot on the board. Anyone out there have any suggestions, dont mind to replace the psu if it needs it, but im not sure thats the case. If the pcie slot is going bad would it cause this behavior? Below is the complete specs of the pc

Intel 945GCNL Mainboard
Intel core 2 duo e6600 cpu
2gb (2x1 gb) Mosel (generic) ddr2 667
320gb wd blue sata hdd
Radeon hd2600xt pcie x16
MSI Geforce 8600gt (test card)
One 80mm case fan
4 pin 92mm cpu cooler thermal take
usb wifi and wireless mouse adapter
No dvd or card readers

start with a new cmos battery. if the battery is weak or dead it can cause no post issue. if it not the battery is may be a bad cap in the power supply or on the mb. use a volt meter to look at the atx voltage. (the power good line).

Actually now that you mentioned it, when I first built or rebuilt this system, I did get an error about the cmos battery. I made all the necessary changes, saved and rebooted and all was fine but it may be something to do with that. Ill change the battery out when I get off work, I have a spare 2032 that is new at home. Ill post back on any changes. Thank you very much

It's likely the power supply. A big clue there is that it takes so long to get it powered up but it runs fine without an add-on video card which is a drain on the unit.

You are probalby running right at the edge of the power it can supply to the system with a video card. Every so often you get lucky and it can send enough power to the computer to turn on. If you can run the system if a very cold room it will likely start a bit more often.

It's not the battery because the system works fine without an add-on video card. If the CMOS battery was bad, it would not work at any time.

Just tested it with an Ultra 500 Watt and it works fine. Guess its time to order a new psu. Thought about replacing board too, found a MSI E350DM-E33 Motherboard and AMD E-350 1.6GHz Dual Core Combo with Radeon HD6310 dont know a lot about those processors but it would be used for working from home as a tech support/CSR agent and some light gaming, aion online and neverwinter, would probably drop in the 8600gt instead of the onboard gpu. any thoughts on how this cpu/gpu performs

That is a weak CPU, it's likely no faster than your E6600. If you want a cheap gaming system, get an AMD A8 or A10 CPU, the onboard video on those are better than the 8600gt by a lot.

You can improve your system by upgrading to 4 gig of RAM along with a faster video card. If you move to a newer motherboard and CPU you will also need to get new RAM along with it. But you will have a better overall system.
