Weird mobo defect after replacing psu.

[threedee]

I have here the Gigabyte GA-DS3R mobo, running fine, except if say power cuts out for whatever reason i cant boot it up until it cools off completely (about 45-60 minutes). So on my old psu i used the trick, where i would momentarily switch it off/on from the back (0.25 seconds) and mobo would POST. (learned it by accident in a fit of rage when my old machine refused to boot for some weird reason, while all components were tested working fine separately, go figure, one of those things...meh)

Now, i have replaced PSU because somehow ALL recent games decided to reboot my machine whenever, which indicates power shortage. So i got 1kw OCZ psu and now i cant use this trick, because a) new psu with protection against surges/brownouts and b) it's a new psu i dont want to screw up...

So, anyone ever had this sort of thing happen ? When "not booting" i get psu power on, hard disks spin up, hdd activity light stays lit constantly although there is no disk activity and no POST comes up no matter how long you wait. Only cure for this in my situation was to sit and wait for 45-60 minutes, watching telly, making lunch, jogging or whatever you do when you have to kill an hour...

Any ideas ?

Just curious, i'm about to replace the system anyway, but it would be interesting to see if anyone else experienced something like this. I'm typing on this machine now, need to reboot it for sound drivers, but wont until i go to sleep because reboot will take an hour...

had this issue before with an Abit board, same as you i think it was the PSU at first and swapped it out, but it still had the problem.

i think the first PSU caused the problem with not enough wattage, that in turn just made the board OVP/OCP very sensitive, to the point that when it had any issue, even a slight overclock witht he new PSU it would just shut down.

and stay that way for 20 mins, sadly it never recovered, i ended up getting an ASUS board, and all was well.

i suspect this is your issue, put it down to experiancen and make sure you got the wattage in future

Oh wattage was just fine, its an old OCZ GameXstream 650w, so it was enough to feed even my 480gtx on top of quadcore (q6600, OC wothout 480gtx, or stock with graphics), 4gb of ram and X-Fi Fatality fps sound card. Also 4 case fans (Antec900 case) Except when i play high end games it chokes on not enough power and dies...... The machine (bought in parts, assembled myself) was weird from the start since i bought it. Didnt send it for rma because i couldnt point a finger at particular problem at the time, only couple of years later it started acting all pants-on-head retarded, thats where i learned the "trick".
