Computer Hiccups

Specs: Windows 7, I5 2400 3.1 Ghz * Gb Ram

Just built my own computer and everything runs great, but the computer will occasionally hiccup for a quick second, not on a regular time, but sometimes when running higher load games (Crysis, Starcraft II, etc). I was wondering if it could be the PSU, motherboard shorts, or temperature (although the GPU and CPU tests I was running seemed fine). Specs as follows:
-MSI P67A-GD65 (B3) LGA 1155 Intel P67 SATA 6Gb/s USB 3.0 ATX Intel Motherboard
-EVGA 01G-P3-1561-AR GeForce GTX 560 Ti FPB (Fermi) 1GB 256-bit GDDR5
-Antec NEO ECO 620C 620W Continuous Power ATX12V v2.3 / EPS12V 80 PLUS Certified Active PFC Power Supply
-Intel Core i5-2400 Sandy Bridge 3.1GHz (3.4GHz Turbo Boost) LGA 1155 95W Quad-Core Desktop Processor BX80623I52400
-G.Skills RipJaw 8 Gb DDR3 1333 RAM
- Thermaltake Frio Overclocking-Ready Intel Core i7 (six-core ready) & i5 Compatible Five 8mm Heatpipes Dual 120mm Fans Intel & AMD Universal CPU Cooler CLP0564
-G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Desktop Memory Model F3-10666CL9D-8GBRL

I really have no clue as to what is causing this, first noticed the problem while playing left 4 dead 2 with Vent open, caused severe lag (>9000 ping) and I noticed that it was the whole computer that froze up after the first time it happened.

I just noticed that whenever these "hiccups" occur, the one of my case lights flashes at the same time, could this mean it is a power surge or PSU problem?

You got an overclocker's heat sink but you also got the i5-2400 which is not overclockable??? If you wanted to overclock you needed the i5-2500K; If you were not then you did not need a massive heat sink (unless tropical temperatures without A/C).

You did not mention your hard drive make and model. The typical front panel LED that periodically flashes is your HD indicator meaning a program is accessing your hard drive. If you purchased a slower hard drive or one with a lower cache then that is possibly your bottleneck and is causing your problem. Your board has the ability to use SATAIII at 6BG/s so if you have only a SATAII 3GB/s drive, especially if it has less than 32MB cache you could be causing the slow down right there.

Do not overlook heat problems, especially if you have not built many computers. Too much thermal compound is nearly as bad as too little since it limits the heat transfer. The more complex heat sink hold downs that come with the heavier heat sinks must be torqued down evenly as well as firmly, too much pressure on one side and you get poor heat transfer over most of the CPU's surface. Install SpeedFan or similar program to monitor your internal temperatures while running programs to give you some clues as to where the problem is. If you are running even a little bit hot with that set up, look for the problem, but I would completely redo the heatsink mounting with fresh thermal compound on freshly cleaned surfaces.

You have to be a little bit crazy to keep you from going insane.

I got the overclocking fan as a means of combating living without air conditioning for two months in the middle of summer, I have my 3 GB/s drive with a 32 MB cache hooked up the SATA II so I know that's not the problem, and I downloaded speedfan, and all temperatures appear normal. This is the first computer I have ever built, but I had watched my older brother build them plenty of times while he was interning. Western Digital Caviar Black WD1001FALS 1TB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive is t hard drive I have, but I honestly don't know what could be causing the problem.

Good HD. Post back your idle and loaded (gaming) temps. Check your BIOS for disabling on-chip graphics in case this is causing the problem. See if lowering the game's settings will eliminate the problem.

I figured it out, my BIOS wasn't configured how I had originally set it up and the on-board chipset was causing the graphics to be all screwy, everything works great now. thanks!

Thanks for letting us know.
