I am writing this account in chronological order so it may appear to ramble on. thanks for bearing with
me and reading this post.
The pc is an HP Pavilion a1742n, AMD Athlon 64x2 dual core 3800+, 1024 megs memory it has nvidia Geforce
6150 LE graphics (onboard) original PSU is 250 watts, OS= windows vista home premium sp2
The PC worked for a week or so, playing call of duty 1 with poor video performance. so i decided to upgrade
the memory and the video card, i researched and found the proper 4 gig ram, installed it and ran the PC a
few days with no problems. (vista 32 bit only recognises 3.5 g of the memory however.)
then I installed the msi radeon 4670-2D1G/D3 graphics card.
The pc ran fine for a week playing call of duty 4, with no problems. I then noticed the games start
page would scramble and pixelate badly if left too long, sort of a screen saver corruption, i think.
I came back into the room to find the on button flashing and no display signal and couldnt get it to run. I
found a tutorial and followed it removing & reconnecting the terminations of the PSU and the PC started for me.
I shut the PC down and brought home a new PSU to try, a thermaltake TR2 430 watt. I installed it but now can not
get the PC to boot up. The power button lights up, the fans all run,the hard drive seems to spin up, but i still
get the no signal msg from the monitor.
I am at wit's end here. thanks for any insight, carp3nt3r.
