my comp restarts 4-5 times during boot [running windows 7] and gives the following error IRQL LESS THAN OR EQUAL.
ubuntu gives me a kernel panic and tells some errors with 'CPU word' being used a lot such as CPU0 idle clock.. etc
i have tested my ram and hdd and they are working fine.
the following sequence takes place:
if i am booting for the first time in the day:
restart 4-5 time throwing errors
works fine here on after
if i shutdown and restart immediately
if i shutdown and restart after 1 hour or so
error cycle repeats again

I had the same problem. I did a RESTORE and even went so far as to reformat my HardDrive and reinstall WINDOWS (XP SP2) but without success.
I did a full scan with PCtools antivirus and it persisted. Then I tried Antimalware and found some trojans etc. This did the trick but once in a while I still get it i.e twice in the past two months. The Antimalware version I use is not the full program (almost a try and buy version without a time limit) Maybe there is still some undetected trojan or malware somewhere on the system. The one trojan was a Windows file !
