System resets, hangs up, BSODs... HELP !!!

[phinix]

Looking for help !!!!

Suddenly my sytem started to reset itself. At the beginning there was no BSODs. Just resets and then hags up during loading the system (XP startup screen with loading strip).
Then it restes again, and again.... never comes back to fully loaded system. Then after a while I got BSOD, but not every time I tried to restart it.
Did clear cmos, bought new mobo, changed ram (memtest gave me no errors on ram), stated with mobo, cpu, ram only, changed hdd, no gpu, onboard only.Only thing I didn't change was CPU.
Can this be a CPU? or am I missing something here?

Please HELP !!!!

Please HELP !!!!

Yah, you're missing the BSOD error code. Did you not look it up before replacing hardware? Did you test any hardware parts before replacing them? Did you try a repair installation? Did you try safe mode? First and foremost, since you're still having issues, you obviously need to lookup the error code in the BSOD. The link to look those error codes up can be found in the GenHard FAQ:

I had it only few times. Now dont have any BSODs. Just resets all the time right after POST table when system supposted to start loading...

So you can't get into windows at all? not even safe mode? If not, then do a repair installation. If the repair fails, you have a hardware problem. You didn't answer any of the other questions I asked.

It must be ahardware problem - repair didnt work, no safe mode, nothing...

Use memtest.org to test your RAM, its also part of the ultimate boot cd.
Visit your drive manufacturer's site to get some HDD Diagnostic tools, they're also part of the ultimate boot cd.
Once in windows, use Prime95/Orthos SmallFFTs torture test for the cpu.
Loop 3DMark to test your GPU.

What PSU do you have ??

After running running Memtest to check the ram, it the next hardware part I would check.
What are your voltages ??
Will it sit in a bios screen for a hour without it resetting itself ??
How warm is the air coming out of the PSU ??

Enermax 500W, dont know what are the voltages.. it stays in bios, no resets. Its warm, but its same as usual, not too hot.
memtest showed no errors....

Run memtest for several passes if you can, typically 4hrs or more.
