I'm having a huge problem that is driving me crazy. My neigbor asked me to look over his computer that was giving problems.
HP Pavilion 7850
Intel Pentium III socket 370 933MHz CPU
Asus CUW-AM Motherboard
3dFX N2544 PCI video card
384MB PC100 RAM (256MB + 128MB)
Fujitsu MPG3409AT 40GB UATA/100 hard drive
The problem is that the pc will not go past the HP logo screen. When the pc is turned on, the HP logo comes up and stays on the screen, it doesnt go past this.
I noticed that the hard drive activity light in front of the pc stays solid. This is a little confusing because to my understanding, this light should be blinking as the hard drive is active. I dont want to think that it is the hard drive the problem because, the pc was able to boot into windows xp once since my friend gave it to me to fix. And I removed the hard drive and connected it to my gateway pc in slave mode, and I was able to run a couple of tests on it, which it passed.
Another thing is that the pc makes beeping sounds when started, but not all the time, just some times it is started. I researched it and the beeping sounds are codes. From what I hear when the PC is turned on, is the beeping sounds are 3-1-4-3. I tried researching this and there is not BIOS beep codes in this range of beeps. But I'm 100% sure that those are the beeps and the order in which they beep.
I tried booting up with only the keyboard, mouse, and monitor connected and still nothing, not boot up past the HP logo screen. I disconnected both optical drives, and all PCI cards (video, network, and modem), to see if that made a diferrence, but still nothing.
I dont know if its the power supply because I see the power supply unit fan spinning, and cpu fan spinning. I heard that you can tell for sure if either one of theses were not spinning.
I even removed the CMOS battery from the motherboard for about 5 minutes to see if that helped in any way, but still nothing.
This is all the info I can provide. I have not left any details out.
Could it be the motherboard? As I said before, I was able to boot into xp once, then never again after that, only thing that happens is the HP logo comes up on the screen and stays there for ever.
