is it my psu?

a few days ago, i started having problems booting. pressing the power button turns on psu, cpu, and gpu fans, plus my hdd and optical. but the computer does not post.

i've taken the entire machine apart, cleaned it, and re-assembled. i've tried booting on different ram in different slots. i've tried a bare minimum boot with just 1 stick ram, monitor connected to integrated graphics, and a keyboard - still no post.

here's the weird bit - if i power on, then hit reset enough times, it will eventually boot. and once it boots, everything runs fine - i can play intensive games and watch hd movies... it will run all day.

here are the machine's specs:

micro-star ms-7529 mobo
core 2 duo e7200, 2.53 ghz
2x ddr2 pc5300 1gb, 667 mhz
geforce 9500gt, 512mb
mercury MKP-4400, 400 Watts
one SATA hard drive
one SATA optical drive

it's a noname prebuilt, i've had it about 9 months.

i don't have access to another psu to test. so i'm down to going out and buying one. is there anything else i can do before i drop $75 that i might not have to spend?
 
like you said in your previous post keeping hittin reset button until it posts, go into bios and set it to boot from cd. download the flash ultility and the bios and create a bootable cd. keep hittin the reset button again to get it to post and it will boot from cd into DOS. and then type in dos the flash utility and bios and it will restart and update.
btw: post make and model of your board and i will check to see if it can be flashed from within windows.
 
sorry i should have mentioned - for the last few days, it has not been booting at all. i can hit reset 50 times and nothing works.

i even replaced the psu, but no luck.

i think at this point i'll just take it in...
 
It will be the motherboard, bios chip. no pont trying to replace anythin else but the bios chip or the motherboard. But if you can keep trying to get it to post and flash the bios, it might fix it.
