My "new" notebook has some really wierd lags during work, youtube video etc etc... Sometimes it has bluescreen during booting, sometimes after reboot. All my drivers are updated and SSD firmware too.

This is my notebook parameters:

Sandy Bridge 32nm Technology
8,00 GB Dual-Channel DDR3 @ 665MHz (9-9-9-24)
LENOVO 12985VG (CPU): 58 °C
SyncMaster (1680x1050@60Hz)
AMD Radeon HD 6630M Series (Lenovo)
Hard Drives
125 GB Crucial M4-CT128M4SSD1 ATA Device (SATA-SSD)

  • What's the blue screen you're getting? When it lags what does the CPU and disk activity look like? – Ƭᴇcʜιᴇ007 Jun 9 '12 at 17:31
  • Bluescreen is displayed for 0,1 second... So I really dont know what it is about... And the lags are really random and I can not watch all day my CPU and HDD activity.. – Marek Javůrek Jun 9 '12 at 18:47
  • Marek, you can find bluescreen information in the event log (look for bugcheck). – Joey Jun 10 '12 at 16:18

Have you run chdsk? If you are blue screening, it sounds like a disk error.

  • result: "Windows has checked the file system and found no problems." – Marek Javůrek Jun 9 '12 at 16:33

The blue screens could be due to faulty hardware, it may be worth sending it back.

Having a fast CPU and disk won't eliminate all lags. Some programs will hang whilst trying to make a network connection (IE and unavailable proxies are guilty of this) which will really slow down your experience no matter how fast everything else is.

  • Ok, I will try to close some network programs. – Marek Javůrek Jun 9 '12 at 18:48

When starting Windows press F8 (or repeatedly hit it until the boot menu appears) and start the memory diagnostic from there (should be under »Repair my computer« or something). I recently had random file corruption on the hard drive as well as five blue screens in two days (which is about five times as much as I expect for the lifetime of the system itself). It was caused by a faulty RAM module.
