Try reinstalling windows, your system might be corrupted
Is it Vista or XP?
Also how much disk space do you have?

[digit i am thinking]

i have installed a fresh copy of xp.
is it a ram problem? how to test it?

[himtuna]

had it been a ram problem
you would have recieved a BOD with message
"begining the dump of physical memory"


fresh copy of xp
was it modified.....?


check for you registry..
or get the dll files replaced ( the ones which are creating problems...find tehm on net)

Can heating up of RAM display the message Physical Dump Of Memory BSOD ?

[digit i am thinking]

i got BSOD saying that
bad_pool_header.
so i again install new copy of xp and try to install drivers.Now mobo cd says that this is not a intel mobo so driver can't be install.
cd can't able to recognise mobo?
so i installed drivers from device manager & updating drivers.while installing video driver pc didnt accept it and rebooted.after some hassle it get installed.
Now condn is like this,
fresh copy of xp with all drivers installed.
still prob. is same .
NO big games(2gb)/prog. able to run.it always gives errors like some files missing or this problem needs to close.

i installed cod4 demo from dvd,it installed without any problem but when run the game it doesn't run giving an error some dll file missing.this dll file is missing from not from windows.I hav played this game before on same machine without any problem.
this is just one example.
my pc gives error to any game or any big software i try to install.

Is your HDD full?

[dheeraj_kumar]

You say you did a fresh install, you mean you did a clean install? wherein you formatted the entire windows partition and installed it?

even then if it did not work, then it might be a RAM problem. I dont think HDD has anything to do with it. Maybe your ram is faulty so data gets corrupted in ram and errors occur in windows. Run Memtest five times to get the average results.

i think prob. is with ram.
but the motherboard cd is not identifying motherboard says mobo is not intel motherboard so drives can't be installed.
is there also problem with motherboard?
