PC too slow, CMOS failure
Hi Experts,
I have a PC that takes forever to boot and shut down. There are no viruses, I defragmented the drive, Removed unnecessary startup files, Deleted the cookies etc... but nothing helped. I ran PC Check , first time it showed Core CPU failure. I blew the dust off of the cpu fans and again ran PC Check, now the CPU error disappeared and it shows CMOS Ram errors, intermittently. The CMOS settings are also lost. The HD tests passed. Does failing CMOS battery give booting problems? Or what else could it be? There are other problems also like not being able to write to CD and Outlook problems.
Please help.
Thanks
Priya

A CMOS battery that was providing bad voltages could cause boot problems, though I don't think it would cause shutdown problems. They are fairly cheap to test (3v) and replace.

Now the PC check says Motherboard CMOS Ram chip failed! Is the MOBO failing altogether? I replaced the power supply to eliminate Power problems too. Still giving intermittent errors.

It seems you have to replace the CMOS battery. Most motherboards have CR2032 batteries that cost no more than a dollar or two and are relatively easy to replace.
You can see an example of replacemnt CMOS Batteries at the following link:
http://shopping.microbattery.com/s.nl/sc.2/category.763/.f?gclid=CMv_8uiAlogCFRtNEgodoFROHQ
if your CMOS chip itself failed (which I doubt), then you will probably have to attend to your mother vendor for a replacement chip
(if it is not soldered to the motherboard)
hope that helps,

if possible, i suggest testing ram and disk :
ram : use memtest86+ from www.memtestorg
disk : http://www.disk-utility.com/hard-disk-low-level-format.html
but, from your description, you may have a burnt cpu, or a bad motherboard too.

You may have to reset the CMOS as well as replace the battery. Unless you leave the machine powerless and "battrey-less" for several minutes while changing the CMOS battery, you need to find the jumpers on the mobo to do this.

Hi again,
I replaced the CMOS battery but still gives the same errors, "Core processor failed", "CMOS Ram failed". It still takes a looooong time to boot and I've never seen it shut down automatically. I have to manually power it off. Is it only the processor or the whole MOBO itself? Any clues?
Thanks

yep, it should work fine when everything is replaced !
can you boot up at all or not? if not, i suggest first disconnecting all devices, and boot with mobo + cpu + 1 ram stick and video card.

Hi ,
I replaced the mobo and everything is fine. No CPU error messages. Thank You all very much for all the support.

BTW, I had to reinstall windows for the shutdown and restart problems.
