|Okay, I made a post and then it erased it all when I hit preview, so here is a short version.|
My computer will power up, all fans runnign full speed and all components seem to be operational. However, my computer does not POST or give any beep/messages (with speakers on full blast). Before this, I was getting a ton of BSOD so I upgraded all my drivers, however this obviously didnt help because its a hardware problem as it wont POST.
Things I have tried:
-switching out ram
-test ram with memtest (before the computer stopped posting)
-removed all ram (got no beep/message)
-removed CPU (got no beep/message)
-removed all video cards (got no beep/message)
I don't think its the PSU because the everything in the computer lights up, fans go at normal speed, and everything seems to have power. However, the PSU fan stopped - but it stopped working months before the problems started. Also, the PSU doesn't get real hot, even after a few hours of play. You see, when I first got the computer I was worried about overheating, because of sli cards, so I added additional fans and paid for "professional wiring" for optimal air flow (hell, it works). No, I havn't tried switching this out is because my older PSU was to old. (didnt have all the proper connectors for even the basic MOBO connection)
My question is:
-is it possible for a PSU to look like it all comes on, but still not have enough power for a MOBO to start POSTing?
Im almost 99% sure its not the ram. I tried using my brothers ram, didnt do anything. Before the POSTing problem happened I tested my ram with memtest for about 12+ hour - got no errors. Also, I have tried all my ram (4 sticks) individually, in different slots, and nothing happened.
I think it "could" be this because before the POSTing problem I did test this and with a 12+ hour test I got 1 error. However, I did take this out completely and my MOBO didnt give me any error. Then problem with this is I can't test my CPU because I don't know anyone with a MOBO compatible with intel.
This is what I ultimatly think it is because I cant get ANY beeps/messages no matter what I tried. I tried reseting CMOS, did nothing. Also, no it is not shorting out in the back (this was made professionally for me and I checked.)
Question about MOBO:
1. Is it possible for it to look like power if flowing through the computer, all parts running normal, and the MOBO still be fried?
2. Someone on another website mentioned that a MOBO test is to see if num/scroll/caps lights work if you press them. Is that a viable way of testing it? (if so, my lights on keyboard wont turn on if pressed)
Anyways, here are some BSOD errors before the POSTing problem:
