BIOS - XP OS ? CPU Spike causing intermittent hang - continuous
Posted on 2005-04-30
Hardware: HP Pavilion ZE4258 [laptop]
Processor: AMD Athlon XP 1.05 GHz [2200+]
OS: MS Windows XP Pro 5.1.2600 SP2
BIOS Version: KA.M1.34 [17.12.2002] SMBIOS 2.3
Other software installed: None [clean XP Pro install]
Whilst typing in wordpad for example, every 3 seconds or so, the system freezes, then continues. So if you're typing, every few words will have missing letters.
If you move the mouse around, again every 3 seconds or so, it freezes, then continues.
Task manager shows a periodic CPU spike every few seconds, going from approx. 2% to 19-23%. I had a look at processes running but could not detect anything unusual placing demands on CPU.
The machine belongs to a friend and came with XP home installed. In an effort to remedy, I did a clean install of Windows XP Pro, full NTFS format etc, replaced memory [new memory I know to be good] and tested. Problem is still there.
I can't find any resource conflicts I/O, IRQ or memory.
The only thing I can think of is a BIOS issue?? If anyone can help, I would be most grateful.
