hmmmm....pretty weird indeed. see if its a hardware problem. test your ram out and try booting into windows and running the programs that you usually run with one ram at a time. see if the problem narrows down to your ram.
have you installed any softwares recently? im thinking also that its a software conflict but i dont see how could that be. hmmm... try testing out the ram and see what goes on. also if you have a anti-virus program, update to the latest virus definition and then run your anti-virus program. if you dont have one i recommend AVG from www.grisoft.com
i use it and it works well. good luck
I would also recommend downloading Ad-Aware (www.lavasoft.de
), updating it, and scanning with. Scan with smart scan first then select the drives u want to scan. 2 different scans. Then scan with housecall at housecall.trendmicro.com.
It could be bad RAM so go online and find a RAM or system diagonistic application. They ususally ask you to create a boot disk. It could also be a bad or damaged CPU. It is not uncommon that they come bad out of the factory or get damaged during shipping. Probably about 5-10% of all processors get to the store bad.
