PC randomly reboots … or not. For the past 2 weeks, my computer simply reboots on its own or just freezes, whether I’m in an app, just surfing or during the reboot. When it comes to a dead stop before rebooting, I hear a click (probably the Viewsonic monitor). Sometimes it just comes to a dead halt without rebooting then I have to hit the power button off then power on to reboot.
 
Also, once in awhile I get a checkerboard screen of multiple colors moving up and down then I have to re-boot. In the past, I’ve religiously done my virus and malware checks. Now I can’t even complete one malware scan before it re-boots or stops.
 
Once I got the following message:
0251: System CMOS checksum bad – default configuration used
 
Any ideas of what the problem could be?
 
The config:
eMachines T1440
1.4 GHz
256 mb RAM
XP Pro
XP Pro Office
PhoenixBIOS 4.0 Release 6.0 vs. 1.05e
 
 
I’ve checked all connections – all is OK.
 
Just in case, where do I get a PSU and/or CMOS battery? It’s been difficult finding a CMOS battery for the T1440 or is it juts a standard?
 
Thanks,
Nickster
