Bsod at 10% overclock

Well I started trying to overclock a 1.7 p4 I had only to find out they were poor at OC'ing. Unfortuantely for me I am a determined person. So I got a p4 2.26 for cheap and tried to oc that. Same problem, would not be stable at 10% and anything after it wouldn't boot. Well I looked into it more and found out my board did not have an agp lock and that was important. So I got a new board, in the mean time I got a SL7923 for very cheap. Well I now have a EPox 4PDA3i-3 the 3.4 and 1 gig of corsair VS3200. So I figure I am ok. No. Now I can make it to 10% stable, at 220 fsb I get a bsod. I run at 47c full load and 30c idle. I have the agp locked and the timings fully relaxed. All of this has no effect and I had the ram at a 5:4 divider. I have literally built a completely new computer, the only thing left is the case. So obviously the problem lies between the chair and the keyboard. Is there some sort of fundamental step I am missing.

That actually may be the stumbling block, namely the PSU that's in the case.
 
Well I changed it recently to a guardian 550w. Don't really know if it is a good brand or not, being that it was only 20 I figure it is a not.
 
Power supply

Here it is, I know it is cheap, but I figure I would only be dealing with it not working at all not affecting an OC. The only thing that is wierd is the 5v is actually at 5.25 other than that the others stay within .1 of what they chould be. I mean the vcore changes a little from 1.55-1.60 but that could be the board as much as the PSU right. Thanks for the help

Generic PSU's can most definatly limit your OC. Mainly, generic PSU's tend to have weak 12v rails. The CPU, video card, and hard drives/cd drives all use the 12v rail, so a PSU can very easily limit an OC. When you are overclocking did you try to increase the vcore at all? A lot of times, stock voltage is not enough for any stable OC. I don't know about your motherboard specificly, but does it have PCI/AGP/SATA locks? If it doesn't it will be almost impossible to get a stable OC. Another thing..3.4ghz Northwoods don't have much headroom for overclocking anyway. While there are some exceptions, I wouldn't count on much more than 3.5 to 3.6ghz in most cases, because 3.4 was the end of the line for northwood. The 1.7ghz P4 would have been a williamette, so that explains why it was a poor overclocker, and they were pretty much utter crap anyway. The 2.26 should have been able to get a fairly decent OC.
 
Always failing on a 10% overclock suggests it could well be a PCI/AGP lock issue. Make sure that they are set to 33/66MHz.
The 3.4 was only really a good overclocker when partnered with a Vapochill. That was more for the multiplier than anything else.
 
Yeah I have the agp locked. I rally think it is coming down to the cpu. It is pretty stable at 210 FSB. After that it gets kind of unstable. I guess I will settle for a 200 mhz oc.
