I have three machines with the exact same hardware and the exact same problem. After I push the power button, the CPU fan runs continuously at a high speed rather than spinning down to a low speed. The IBM BIOS screen never comes up; in fact, nothing gets displayed on the screen. It appears that the CPU and RAM are not heating up but the video card is.
I've replaced the CMOS battery, but that had no effect. Running only one RAM module didn't help either. What is the problem and how can I fix it?
Specs:
Intel P4 1.8 GHz
2 x 256MB PC133 SDRAM
IBM 40GB IDE
NVIDIA Vanta LT AGP
1Have you tried testing with a different video card? Do the systems give POST beeps if you pull Video and/or RAM? Did the machines EVER work in this configuration? – Ƭᴇcʜιᴇ007 – 2011-08-31T19:42:25.143
I have 27 other machines in the same configuration that ran without a problem. There's no on-board video and I've tried all RAM configurations without any POSTing. I don't have another video card to test with, though I could just swap a video card from a working machine. I did have another machine that never restarted properly (similar symptoms). However, it worked after pulling out the power cable for 10-15 seconds, then starting it back up again. – Wesley – 2011-08-31T20:56:18.880
If you pull ALL the RAM and Video out, does it give you POST beeps? If not, then the motherboard is probably shot. If it does (it should give you 'no RAM' beeps), then stick the RAM back in, but no video. At this point it should give you 'no video' beeps, if it does, then you know the video card is shot. – Ƭᴇcʜιᴇ007 – 2011-08-31T21:03:55.790
I am getting a 1-3-3-1 beep code without RAM or video, meaning the motherboard is still working and detects the absence of RAM. With just video, I still get the beep codes. With the RAM in and no video, I am back with the same symptoms as mentioned before. Does this mean that the RAM is faulty? How could I check if I can't POST? – Wesley – 2011-08-31T23:39:14.650
Sounds like bad RAM. Can you try it with just one stick at a time? Perhaps pull RAM from one of the working 27 machines? – Ƭᴇcʜιᴇ007 – 2011-09-01T00:10:04.550
Followed your advice, and turns out it is bad RAM. Thanks! (Now, how will I select an answer for this??) – Wesley – 2011-09-03T15:46:13.113
I'll put one in. :) – Ƭᴇcʜιᴇ007 – 2011-09-03T17:31:30.250
