I've been battling this problem for a very long time and any help will be greatly appreciated.
I have a spare PC that I've been slowly bringing back so I can give it to my father whose computer died a couple weeks ago. My problem is this: When I boot up, I see the POST messages, it gets to the RAM check, finds all the RAM and Says its 'OK' and then it freezes before displaying the IDE check (where it lists all the IDE drives I have installed). I see the message on the bottom telling mt I can press 'DEL' to enter Setup, however the keyboard is unresponsive. I have seen a few posts with similar issues and unfortunately none of them had a solution. Here are my system Specs:
MB: SY-KT333 SOYO Dragon Lite
CPU: AMD Athlon XP 2400 (listed either as a 1800+ --or-- 'Unknown CPU 1500' during POST)
RAM: (1) 1GB PC2700 333Mhz
HDD: (1) Maxtor 80GB
Optical: (1) DVD drive
(1) DVD-RW drive
PSU: 350W 80+ "green"
Video Card: ATI Radeon XT6400 (not certain about the 6400 part... but it is a Radeon)
OS: Windows XP Home SP3
Now, the weird thing is that when this happens, all I have to do is hit the soft reset button on the case and then it starts up fine, however, when I start using a CPU intensive application (in this instance I started a Norton Virus scan which jumps the CPU usage up to mid 90's) the computer restarts itself and then back to freezing up during POST, I soft reset, all is well, then it restarts...etc, tis a vicious cycle. And FYI I did uncheck the 'Automatically Restart' option in the System menu, which should let me see a BSoD if one is being generated, however I never see a BSoD, it just restarts.
I have disconnected everything from the MB except for the video card, RAM, HDD and PSU. All the optical drives, and other PCI cards (Ethernet, extra USB card) are disconnected.
I have replaced the RAM stick, put it in all three DIMM slots, replaced the PSU, replaced the HDD and cleared the CMOS via the MB jumper (multiple times in fact). The only things I have not replaced are the MB and CPU (because if I have to spend the money to replace these than I might as well rebuild an entire new one).
ANY help will be greatly appreciated!
Thank you for your time
