Bios Checksum Error

post #1 of 2
Thread Starter 
Recently, I have been experiencing seemingly random crashes and system instability. The symptoms are something like firefox crashing every time I open it or game graphics become screwy, to other pieces of software not loading at all. I have had my system overclocked anywhere from 2.6 to 3.2Ghz in the last year, and this has only been happening recently. Basically the computer locks up or BSOD's and reboots to give me a BIOS boot lock manager with a bios checksum error and a string of fast beeps. If I turn the power off for a few seconds and then back on the problem seems to vanish temporarily, however all of my bios settings have been reset to the defaults. I also can then proceed to re-overclock my system to upwards of 3.1-3.2 GHz and game or browse the web all evening without so much as a hiccup. I really can't pinpoint the problem, but I suspect it might have something to do with heat, yet the system isn't overly hot, hovering around 39-41c idle. It has been warmer ambiently lately, ALOT warmer than the past 6 months and I suspect this might be the problem. I guess though my concern is the BIOS boot lock manager and BIOS CHECKSUM error I am getting. Is this a symptom of a failing system or something? I am experiencing this more than I would like to be, almost every day. It usually happens when I leave the system IDLE for awhile, or when the ambient temps change so, this definitely could be the problem. So what do you think is going on?

Another thing, I have ran high voltages, but nothing extreme, and not amount of voltage makes the system completely stable. Mind you I have had problems even running at this CPU's stock speed of 1.8GHZ, but rarely and it seems to clear up shortly after downclocking.

1)check out u r CMOS battery it might have drained

2) reflash u r bios with same of better bios from u r manufacturer

hope this will fix the issue , and while flashing remember to clear cmos
